Working technical tool
IPE / HEA / HEB Series Comparator
Enter the designation as it appears on your drawing. The comparator resolves the series and the nominal size, flags a designation that cannot be resolved to one section, and keeps the material grade in a separate layer. It identifies and cross-checks — it does not design.
Section inputs
Resolution is derived from what you enter. Nothing is looked up.
Comparator output
Nothing entered yet. Start with the designation including its series prefix — IPE, HEA and HEB all contain sections at the same nominal depth, so the prefix is what identifies the section.
Send this line item for technical review
The line item built above is attached exactly as you entered it — designation, resolved series, size, grade, quantity, destination and required documents. Unresolved items travel with it as open questions rather than being resolved on your behalf.
Enter section inputs above and they will be attached automatically.
Method, formula and data conditions
How the reference works, and what it deliberately will not do
This page identifies and compares section designations. It does not tabulate dimensions or masses of its own, because those values belong to the governing standard and change with its edition. What follows is the method, the unit system, and the boundary of what the output means.
Resolution method
- 1Parse the designation into series and sizeThe series prefix (IPE, HEA, HEB) and the numeric size are extracted separately. Both are required — neither alone identifies a section.
- 2Reconcile against a separately stated seriesIf a series is also selected in the form, it is cross-checked against the prefix you typed. A disagreement is reported as a conflict, not resolved silently in favour of one.
- 3Reject a generic shape nameA designation such as 'I beam' or 'H beam' matches several standardized series. The comparator blocks rather than returning the nearest match.
- 4Keep geometry and material as separate layersThe designation fixes geometry only. The material grade and its standard are captured as independent fields and never inferred from the section.
- 5Report what remains unresolvedMissing grade, document level or destination are listed as open items. They travel into the RFQ as questions rather than being filled in.
Formula and unit conditions
No mass calculation is performed here. Where an order mass is needed, it is derived from the unit mass tabulated in the governing dimensional standard for that exact designation, multiplied by the ordered length and item count. The comparator does not carry unit-mass values, so it cannot return a total mass — and a figure assembled from an unversioned table would not survive verification at goods-in.
- Unit system: metric throughout, unless a project states another basis explicitly. SI and inch-pound values are never mixed inside one comparison.
- Every numeric field requires its unit to be written in. The comparator does not assume one and does not convert silently.
- Nominal dimensions and masses are properties of the standard's edition, not of the series name. Two editions can differ.
Source hierarchy and applicability
- 1. Project documents governThe drawing, the section schedule and the governing code decide which designation applies. This page never overrides them.
- 2. The dimensional standard defines the valuesNominal dimensions and masses for hot-rolled I and H sections are tabulated in the dimensional standard. Its edition is what makes a figure verifiable.
- 3. The material standard defines the gradeComposition and properties sit under a separate material standard. The section designation says nothing about them.
- 4. This page identifies and cross-checksIt resolves a designation to a series and size, flags ambiguity, and assembles the RFQ line item. That is the whole of its authority.
Limitations
- The comparator returns no dimension, mass, mechanical value, stock status, price, lead time, origin or certificate.
- A definitive result is blocked when the series or the designation is ambiguous — the nearest match is never substituted.
- Nothing here is a structural check. Adequacy for the design is determined by your engineer against the governing code.
- The cited standard establishes scope and method. It does not establish availability, origin or project approval for any order.
Procurement-grade worked examples
What the comparator returns, and what changes downstream
Each example below shows the input, the method applied, the result, how to read it, and the decision it changes. None uses a real client, project or order — the entries are illustrative designations of the kind that appear on drawings.
- Input
- IPE 300 · grade S355 · EN 10204 3.1 · 18 t · Jebel Ali
- Method applied
- Series prefix IPE parsed; size 300 extracted; no series mismatch; grade, document level and destination all stated separately.
- Result
- Section identified — IPE series, nominal size 300.
- Interpretation
- The designation resolves to one section, and the material layer is stated rather than inferred. This is the shape an RFQ line item should arrive in.
- Decision impact
- Proceed: transfer the line item into the enquiry, and cite the governing dimensional standard's edition on the schedule.
- Verification step
- Confirm against the project's section schedule that IPE 300 is the specified series — not HEA or HEB at the same nominal depth.
- Input
- HE 200 · grade not stated · quantity stated
- Method applied
- The 'HE nnn' form without a series letter cannot be resolved — it matches HEA and HEB at the same nominal depth, and those are different sections.
- Result
- Verify first — series unresolved, grade missing.
- Interpretation
- The comparator returns the ambiguity rather than guessing. HE 200 A and HE 200 B differ in flange and web thickness and therefore in mass.
- Decision impact
- Hold the enquiry until the drawing author states the series letter. Quoting a guess narrows the field to the wrong section.
- Verification step
- Check the section schedule for the series letter, or ask the engineer to confirm which of the two was intended.
- Input
- "I beam" · size not stated
- Method applied
- A generic shape name matches several standardized series. There is no numeric size and no prefix to reconcile against.
- Result
- Blocked — no section can be identified.
- Interpretation
- This is the most expensive input to receive, because any section chosen from it would be a substitution made by the supplier rather than a specification from the buyer.
- Decision impact
- Return to the drawing. The series prefix and the size are both required before a line item can be assembled.
- Verification step
- Obtain the full designation from the drawing or schedule before re-entering.
| Example | Buyer implication | Applicability / limitation | Resulting RFQ action |
|---|---|---|---|
| IPE 300 fully specified | The line item is comparable across quotations because the same fields are stated for each. | Applies to the IPE series only. The same nominal depth exists in HEA and HEB as a different section. | Transfer designation, grade, quantity, destination and document level unchanged. |
| HE 200 without a series letter | Quoting now would price whichever section the supplier assumed — a substitution the buyer did not make. | Ambiguity is inherent to the 'HE nnn' form; it is not a data gap this page can close. | Hold. Return to the drawing for the series letter, then re-enter. |
| Generic shape name | Any output would be a supplier-chosen substitution rather than a buyer specification. | The name matches several standardized series with different geometry and mass. | Blocked. Obtain the full designation before assembling the line item. |
Standards and tolerance context
How standard, grade and tolerance change what the chart means
A dimension read from a reference is only half the specification. The dimensional standard fixes geometry; the material standard fixes the grade; the tolerance clause fixes what deviation is acceptable at goods-in. Each is a separate layer, and each has its own verification.
| Layer | What it fixes | Source and condition | Buyer implication → RFQ field |
|---|---|---|---|
| Section designation and nominal dimensions | Which geometric section the name refers to, and its nominal depth, width and thicknesses. | The current edition of the dimensional standard for hot-rolled I and H sections. Values are nominal, stated in metric units. | Cite the edition on the schedule — a value from an unversioned table is unverifiable. → Designation + reference edition fields |
| Unit mass | The mass basis used for estimating, freight and quotation comparison. | Tabulated in the same dimensional standard, per designation. Theoretical and actual mass differ. | State which mass basis the quotation uses. → Quantity / mass basis field |
| Dimensional tolerances | The permitted deviation on each dimension, which is what the connection detail actually relies on. | The tolerance clauses of the governing dimensional standard, or a project-specified class. | Tolerance is never implied by the designation. → Tolerance class field |
| Material grade and standard | Composition, strength and toughness — the material the section is made from. | A separate material standard, together with the project's supplementary requirements. | The chart says nothing about grade. → Grade + material standard fields |
| Manufacturing route and delivery condition | How the material was produced and in what condition it is supplied, which constrains weldability and fabrication. | Defined by the material standard and the purchaser's selected options. | Raise it if the fabrication route depends on it. → Supplementary requirements field |
| Coating or finish | Surface protection where the service environment requires it. | A coating or paint specification, separate from both dimensional and material standards. | Sits outside the section reference entirely. → Coating system field |
| Inspection and test documents | What evidence the delivery must carry and who validates it. | The EN 10204 level named by the project, not implied by the grade or section. | Name the level in the enquiry. → Documents field |
Evidence note. This page tabulates no dimension, mass or property value for any designation. Those values belong to the governing standard at a stated edition and are verified against it and against the certificate for the material supplied. Where a figure matters to your estimate or your design, read it from the standard edition your project cites.
Applicability boundary: each route above is a decision aid for the layer it covers — the dimensional theme, the section standard, or the material grade. None substitutes for your project's governing edition, and none implies availability for a specific designation or quantity.
Verification and misuse controls
Where this reference gets misused, and how it is caught
A dimensional chart is one of the most frequently misapplied documents in procurement, because it is easy to read and easy to read wrongly. These are the errors we see, what each one costs, and the control that catches it.
| Requested evidence | What it verifies | Who supplies / verifies | When required | Quotation / project dependency |
|---|---|---|---|---|
| Full section designation | That the item ordered matches the series and size on the drawing, not a similar section at the same depth. | Buyer, from the drawing or section schedule. | Before the enquiry is issued. | The supplier cannot supply the series letter — only the buyer's documents can. |
| Cited reference edition | That the nominal values being used come from a known edition and can be checked. | Buyer / project specification. | At the point values are transferred to the RFQ. | Omitting the edition makes a dimension or mass figure unverifiable at goods-in. |
| Tolerance requirement | What deviation is acceptable on each dimension and on mass. | The governing dimensional standard, or the project's specified class. | Stated in the enquiry. | Not implied by the designation. Left open, it becomes a dispute at goods-in. |
| Inspection certificate (EN 10204 level) | That the delivered material meets the project's evidence requirement, at the level the contract names. | Manufacturer, or an independent body for the higher levels. | At the project's inspection hold point. | The level is set by the contract — this page cannot supply or imply a certificate. |
| Material identification marks | That the delivered section matches the grade and product form ordered. | Supplier, against the governing material and dimensional standards. | At goods-in, before the section enters fabrication. | Depends entirely on the designation being unambiguous in the order. |
| Dimensional verification on receipt | That the delivered section matches the designated geometry within tolerance. | Buyer's goods-in inspection, using the project's method. | On receipt, before fabrication. | The method and sampling are the buyer's; this page sets no inspection regime. |
Common input errors and their controls
- 1Nominal size entered without the series prefixA bare number matches several series. Control: the comparator blocks and asks for the prefix rather than returning the nearest match.
- 2Generic shape name used as a designation'I beam' or 'H beam' cannot identify a section. Control: rejected outright, because any output would be a supplier substitution.
- 3Mass taken from an unversioned tableValues are properties of a standard's edition. Control: the line item requires a cited reference edition before it is transferable.
- 4Grade inferred from the sectionGeometry says nothing about material. Control: grade is a separate field and its absence is reported as an open item.
- 5Chart output treated as design approvalA dimensional reference is not a structural check. Control: the checklist states the boundary at every result.
Engineering review is required whenever the output is used for anything beyond identification and comparison — member sizing, connection design, fatigue or seismic assessment, or any check against the governing code.
Product decision handoff
Where the result goes next
A resolved designation is not the end of the decision. Depending on what is still open — the section family, the material grade, or the application that sets the service conditions — one of these related pages carries the next step.
The section family is still open
When the member role or the connection geometry is undecided, compare the section family before the designation is fixed. A resolved size without a resolved series is not yet a specification.

Where slender members, bolted connections and sustained wind loading govern, the application changes the toughness and straightness requirements — not the section geometry.

What each destination route requires you to state
- Delivery locationPort of discharge, project site or free-zone address changes the delivery leg, the documents at each hand-over and who bears the cost between them.
- Documentation setCustoms entry requires documents that vary by destination and commercial term. Certificates, packing lists and marking requirements are agreed in the enquiry.
- Delivery termThe Incoterm decides where responsibility transfers and which charges sit inside the quoted price.
- Mass basisState whether the quotation is built on theoretical or actual mass, so quotations can be compared line for line.
These routes describe destination planning inputs. They do not assert that any market is served by a local branch, that stock is held anywhere, or that any destination is currently reachable — availability is confirmed at quotation.
Expert insight
How a reference chart becomes an unverified specification
A dimensions chart is useful precisely because it is easy to read. That is also how it becomes a purchase specification nobody verified: a value is copied from a table, the series prefix is dropped because it looked redundant, and the supplier is left to choose a section.
Verify-first checklist
Work through these six items before a value from any chart reaches an enquiry. Each is something the reference cannot answer for you.
- 1Confirm the series, not just the sizeIPE, HEA and HEB all contain sections at the same nominal depth. The prefix is part of the designation — without it, the size does not identify a section.
- 2Cite the standard edition you read the value fromNominal dimensions and masses are properties of an edition. A figure without its edition cannot be checked at goods-in.
- 3Separate geometry from the material gradeThe chart fixes geometry only. Composition, strength and toughness sit under a separate material standard and a separate RFQ field.
- 4State the mass basis explicitlyTheoretical and actual mass differ. Say which the quotation is built on, or two quotations for the same section cannot be compared.
- 5Confirm the tolerance basisPermitted deviation comes from the dimensional standard's tolerance clauses or a project class. It is never implied by the designation.
- 6Keep design approval where it belongsA dimensional reference is not a structural check. Adequacy is determined by your engineer against the governing code.
Buyer implication. Treat chart output as a verified designation aid, not structural design approval. The RFQ must retain the governing material standard and the project-specific tolerances, or the designation arrives without the requirement it was meant to serve.

Evidence-led buyer advantages
What we do about the ways a chart gets misread
Each item starts from a real concern that follows from using a dimensional reference, states the practice that addresses it, and ends at the outcome it produces. None rests on a claim about scale, stock or price that this page cannot substantiate.
- Buyer concern
- The designation arrives without its series
- What we do
- We return the ambiguity instead of choosing a section — the resolver blocks where the prefix is missing or the entry is a generic shape name.
- Procurement outcome
- The section quoted is the one your drawing specifies, not the one we found nearest to it.
- Buyer concern
- Geometry gets confused with material
- What we do
- We keep the section designation and the material grade in separate fields, and report a missing grade as an open item rather than inferring it.
- Procurement outcome
- The enquiry carries both layers, so the quotation is built on the material you specified.
- Buyer concern
- A value is used without its reference edition
- What we do
- We require the reference edition to be stated before a value is treated as transferable, and we hold no dimension or mass values of our own.
- Procurement outcome
- Every figure on the enquiry can be checked against the edition it came from.
- Buyer concern
- A reference is treated as a design check
- What we do
- The boundary is stated at every result: the comparator identifies and compares; it does not size members or verify adequacy.
- Procurement outcome
- Design responsibility stays where your project placed it, and the RFQ does not imply an approval we cannot give.
- Buyer concern
- Requirements get lost between chart and order
- What we do
- The line item carries every field you entered, in your own wording, with unresolved items flagged as questions.
- Procurement outcome
- What you specified is what is quoted and what is ordered. Nothing is normalised silently.
- Buyer concern
- Commercial terms are assumed
- What we do
- We build the quotation on the stated destination, Incoterm and mass basis, and name the inputs still missing rather than filling them in.
- Procurement outcome
- The delivered cost reflects the delivery you actually asked for, on the mass basis you chose.
Advantages describe procurement practice. They make no claim about plant capacity, stocking position, delivered tonnage, pricing position or certification status.
From enquiry to delivery
Who owns what, at every stage
A section designation moves through defined stages on its way to an order. Each stage below names the concern it resolves, who owns it, what has to be supplied, what comes out of it, and the risk if it is skipped.
| Stage | Buyer concern | Owner | Required input | Evidence / output | Risk if skipped | Next action |
|---|---|---|---|---|---|---|
| Designation resolution | A size without a series does not identify a section. | Estimator / engineer | Drawing or section schedule with the full designation. | Resolved series and nominal size. | A different section is quoted and ordered. | Run the Series Comparator. |
| Reference verification | A value without its edition cannot be checked. | Estimator | The dimensional standard edition the project cites. | Dimensions and mass with a citable source. | A value is disputed at goods-in. | Cite the edition on the schedule. |
| Material layer | Geometry says nothing about the grade. | Engineer / project | Governing material standard and grade. | Grade and standard stated separately. | The supplier infers a grade. | Add the grade to the enquiry. |
| Enquiry issued | Quotations cannot be compared. | Buyer / procurement | Designation, grade, quantity, mass basis, destination, documents. | A complete line item. | Suppliers quote on different assumptions. | Send the line item. |
| Technical review | Project acceptance is not the supplier's to give. | Noor Deira Steel — commercial department | The enquiry and any project specification. | Open items identified and returned to you. | Unresolved items become assumptions. | Close the open items. |
| Order and production | The section must match the approved designation. | Supplier / mill | Confirmed order and delivery schedule. | Production against the stated route. | A requirement discovered too late to change. | Confirm documents before release. |
| Goods-in verification | The delivered section must match the designation. | Buyer / QA | The designation, tolerance basis and inspection plan. | Dimensional and identification check. | A similar section accepted as the designated one. | Verify against the governing standard. |
Buyer FAQ
Questions that come up after the chart is read
These are the questions estimators, engineers and buyers raise once a designation has been taken from a chart — not what these series are, but what still has to be pinned down before the section can be ordered.
Our schedule says 'HE 200'. Which series is that?
It is not one series. A designation written as HE 200 without the letter suffix is ambiguous — at the same nominal depth the wide-flange series differ in flange and web thickness, so HE 200 A and HE 200 B are different sections with different masses. Ask the drawing author to state the series letter, or confirm it against the project's section schedule before the value is transferred into the RFQ.
Can I order from this chart using just the nominal size?
No. The numeric size alone does not identify a section. IPE, HEA and HEB all contain sections at the same nominal depth, and the series prefix is part of the designation. Give us the full designation — series prefix plus size — and we can identify one section rather than guessing the nearest match.
The chart gives a mass. Can I use it for the purchase order quantity?
Use it for estimating, not as the ordered quantity. Mass tabulated in a reference is nominal or theoretical; purchase quantity and shipping mass must be reconciled against the exact section standard, the ordered lengths, permitted tolerances and any fabrication additions. The RFQ should state which mass basis the quotation is built on so quotations can be compared.
Which edition of the dimensional standard should the schedule cite?
The edition your project's governing documents reference. Nominal dimensions and masses for hot-rolled I and H sections are tabulated in the current edition of the dimensional standard, and values can change between editions. Citing the edition on the schedule is what makes the figure verifiable — a value from an unversioned table cannot be checked at goods-in.
Does the section designation tell you what material I need?
No, and this is the most common conflation. A designation such as IPE 300 or HEB 200 fixes geometry only. The material grade and its standard are a separate layer, and the inspection document level is a third. All three belong in the enquiry, because the supplier cannot infer the grade from a section name.
Can this chart confirm my section is adequate for the design?
No. This is a dimensional reference and a designation aid — it is not a structural check and not project approval. Structural adequacy is determined by your engineer against the governing code and the actual load cases. Our role is to make sure the section the quotation is built on is the section your drawing specifies.

Formula and method
What is computed here, and what is deliberately not
The comparator performs identification logic, not arithmetic. It returns no mass, no section property and no capacity figure — because each of those depends on a value that belongs to a standard edition this page does not carry.
| Computation | Method and unit condition | Why it is not performed here | Buyer action → RFQ field |
|---|---|---|---|
| Series and size resolution | Deterministic string parse of the designation into series prefix and numeric size, cross-checked against any separately stated series. | Performed here — this is identification, not measurement. | Enter the full designation. → Designation field |
| Unit mass | Unit mass for a designation is tabulated in the dimensional standard; order mass = unit mass × ordered length × item count. | The comparator carries no unit-mass values, because they are properties of a standard edition that changes. | Read the value from your cited edition. → Quantity / mass basis field |
| Section properties | Second moment of area, section modulus and radius of gyration are tabulated per designation in the standard. | Not returned here — and not a substitute for a structural check even when read correctly. | Take them from the standard, and have the design verified. → Design responsibility field |
| Member capacity | Requires load cases, effective lengths, buckling and the governing code, none of which this page holds. | Outside the scope of a dimensional reference entirely. | Belongs to your engineer, not to the supplier. → Not an RFQ field |
| Unit conversion | Metric throughout. Any SI to inch-pound conversion requires an explicit stated step and is never applied silently. | Silent conversion is how the wrong section gets ordered. | State the units of every value you enter. → Units stated in each field |
Why the distinction matters
- Identification is safe to automateParsing a designation and cross-checking a series is deterministic. The same input always yields the same answer, and the answer is verifiable.
- Tabulated values are notA dimension or mass is a property of a standard edition. Reproducing it without its edition produces a figure that looks authoritative and cannot be checked.
- Arithmetic hides assumptionsA derived mass or capacity figure carries the assumptions used to produce it. Presenting the result without them is what turns a reference into a wrong specification.
- The boundary is stated, not impliedEvery result on this page says what it does and does not establish, so the output cannot be mistaken for an approval.
Worked examples
Estimator-grade examples with the arithmetic shown
These examples take a resolved designation through to the estimate, showing where each figure comes from. The unit masses used below are illustrative placeholders for the method — not values — and must be replaced with the figure from your cited edition.
Order mass from a resolved designation
- InputIPE 300 · grade S355 · 12 m ordered length · 40 pieces · EN 10204 3.1
- Step 1 — resolve the designationSeries prefix IPE parsed, size 300 extracted. No mismatch against a separately stated series.
- Step 2 — read unit massTake the unit mass for IPE 300 from the dimensional standard edition your project cites. The value is not held on this page and is not supplied here.
- Step 3 — compute order massOrder mass = unit mass × 12 m × 40 pieces. Substitute your edition's unit mass, and state the unit (kg/m) you substituted.
- Step 4 — interpretationThe figure is a nominal or theoretical mass. It is suitable for estimating and freight planning; it is not the invoiced quantity.
Confirm the series is IPE and not HEA or HEB at nominal depth 300, and cite the edition the unit mass came from.
Comparing two quotations for the same section
- InputHEB 200 · grade noted as S355 · 9 t stated on both enquiries
- Step 1 — check the mass basisAsk both suppliers whether 9 t is theoretical or actual mass. If the bases differ, the quantities are not the same tonnage.
- Step 2 — check the section resolvesHEB 200 resolves cleanly. Confirm the drawing does not specify HEA 200, which is a different section at the same nominal depth.
- Step 3 — check the material layerConfirm the grade and its material standard are stated, not inferred from the section designation.
- Step 4 — interpretationTwo quotations built on different mass bases or different grades cannot be compared line for line, regardless of the prices.
Reconcile the mass basis and the governing material standard before any price comparison is made.

A downloadable spreadsheet would reproduce dimension and mass values without their standard edition, and would be copied into estimates long after the edition changed. Instead, the comparator produces a copyable line item — carried in your own wording, with every unresolved item visible — and the values themselves are read from the edition your project actually cites.
- Copy the line item into your estimate or enquiry document.
- Substitute dimension and mass values from your cited edition, recording units.
- Keep the reference edition on the schedule so the figure can be checked at goods-in.
- Re-check the line item whenever the cited edition is superseded.
