Hollow Section Dimensions Chart
Use this hollow section dimensions chart as a verified reference to build an RFQ line, not as proof of stock or final design compliance. Filter by shape and standard, disclose units/method, and separate theoretical/reference values from supplier-certified shipment data.
- Shape & standard
- Unit / dimension method
- Wall & tolerance basis
- Theoretical vs certified
- Verify before RFQ

Working technical tool
Hollow Section Dimension Filter
A reference filter that turns a hollow-section shape, standard family, unit system and dimension into a verified reference row and a copyable RFQ line. It never invents a complete size table: it validates the inputs, echoes only verified fields, and puts a publication blocker on any value that cannot be sourced to the governing standard, project specification or mill certificate.
Result
Shape and governing standard required
A hollow-section dimension is only meaningful with a stated shape and a stated standard family and edition — for example EN 10219 (cold formed), EN 10210 (hot finished), or the ASTM A500/A1085 route. Select both so the chart identifies the reference the value answers to. Dimensional values alone do not establish wall, grade, material, finish or final design compliance.
Governing standard & edition
Every dimension is a reference value under a stated standard family and edition — EN 10219 (cold formed), EN 10210 (hot finished), or the ASTM A500/A1085 route. The chart names its source; it never invents a value.
Unit system coherence
Outside dimensions, wall and length are kept under one unit system — metric (mm) or imperial (in) — converted consistently so no false precision is created between shape, wall and length.
Theoretical vs certified
Reference values are separated from actual stock, price, lead time and certified shipment data. Unit weight implied by a cross-section is theoretical until confirmed against the MTC and shipping records.
Publication blocker
A specific numeric section-property value is published only when the current standard, the project specification or a verified mill/MTC value supports it. Otherwise the cell is blocked, never filled with an estimate.
Method, formula & data conditions
How the reference values are derived, and where they stop
This chart is a reference that states its method, unit system, source hierarchy, edition/date, assumptions, applicability and limitations. It separates theoretical/reference results from supplier-certified values and blocks the publication of any value without a source.
Method
- Reference dimensions keyed to a stated standard family and edition — never an anonymous chart.
- One coherent unit system (metric mm or imperial in) across outside dimension, wall and length.
- Unit weight implied by a cross-section is theoretical until confirmed against the MTC and shipping records.
Source hierarchy & limitations
- Governing current licensed standard and edition first; project specification second; verified mill/MTC value third.
- EN 10219 and EN 10210 are not interchangeable; source square/rectangular sectional properties are not equivalent.
- Reference dimension is not stock, grade, finish, wall-standard table or final design compliance.
Data conditions
A reference row is published only when the shape, standard and unit system are stated. A numeric wall thickness, radius, corner detail, unit weight or section-property figure is blocked unless the current standard, the project specification or a verified mill/MTC value supports it. This boundary is what keeps the chart a decision aid rather than a source of invented values.
Procurement-grade worked examples
From a dimension to an RFQ line, without inventing a figure
Each example is a clearly labelled hypothetical input that shows how to turn a hollow-section dimension into a complete RFQ line. None of these reflect stock or a company project; each teaches the input-to-RFQ method.
Hypothetical example
SHS 100 × 100 × 4 mm
Input: Rectangular/square support member; outside 100 × 100 mm, wall 4 mm, length 6000 mm, metric.
RFQ line: Hollow section, SHS 100 × 100 × 4 mm × 6000 mm, EN 10219 (edition to be confirmed), unit metric; tolerance per the standard edition — wall-standard table, grade, finish and stock verified before RFQ.
Shows the exact shape, outside dimensions × wall × length, standard and unit in one RFQ line so no inferred diameter or wall slips in.
Hypothetical example
RHS 200 × 100 × 8 mm
Input: Rectangular beam with directional stiffness; 200 × 100 mm, wall 8 mm, length 8000 mm, metric.
RFQ line: Hollow section, RHS 200 × 100 × 8 mm × 8000 mm, per governing project specification (edition to be confirmed), unit metric; section-property field (e.g. Iy) verified against a current source before use.
Shows how an axial (Iy) vs transverse section-property distinction must be verified before a value is read off a reference.
Hypothetical example
CHS round tube
Input: Round hollow section for a support post; outside diameter to be confirmed against standard, wall to be confirmed, imperial.
RFQ line: Hollow section, round (CHS), ASTM A1085 series (edition to be confirmed), outside and wall to be confirmed in imperial; dimensions only — grade, mechanical basis, finish and stock verified separately.
Shows the case where the dimension is not yet fixed: the RFQ carries the standard and the “to be confirmed” fields rather than an invented diameter.
Standards & size context
A decision-grade specification on the reference, with its evidence warning
The governing standard family/edition and the project specification fix the scope, tolerances, dimensions, sectional properties and ordering requirements for the hollow section. Every row carries an explicit evidence warning — the publication of unsourced numeric values is blocked.
| Reference field | Method / unit | Source | Condition / evidence warning | RFQ action |
|---|---|---|---|---|
| Shape & outside dimension | Stated shape (SHS / RHS / CHS) and outside (side) dimension under one unit system | Reference chart keyed to standard family/edition | A reference value, not stock, grade, finish or design compliance | State shape, outside dimension, wall, length, unit and standard |
| Wall / thickness | Wall per the standard's wall table (blocked unless sourced) | Current standard/edition or project specification | Publication blocked without a current source or verified MTC value | Carry the wall and tolerance basis explicitly |
| Radius / corner detail | Per the standard family — cold formed vs hot finished differ | Current standard/edition | Not interchangeable between EN 10219 and EN 10210 | Confirm the radius/corner against the route and edition |
| Unit weight (reference) | Theoretical per cross-section; actual weight is supplier-certified | Reference derivation — not a shipping weight | Theoretical reference only; actual weight from MTC and shipping records | Request actual weight declaration with the MTC |
| Section-property field (Ix, ry, etc.) | Per the governing standard's sectional-property tables | Current standard/edition or project spec | Verify the value against the governing edition; source square/rectangular properties are not equivalent across EN 10219/10210 | Verify the property source before use |
| Tolerance & dimensional inspection | Tolerance per the stated standard/edition | Current standard/edition + dimensional record | Dimensional record requested, never implied | Request the dimensional/gauge record with the MTC |
These tables are decision aids and carry no inventory value. Any gauge, weight, dimension, tolerance, radius or section-property figure is confirmed against the governing standard/edition, the project specification and the mill certificate before quotation. Price on request.
Registered reference routes
Anchor the standard and the size chart before RFQ
Confirm the EN 10210 standard route where scope, tolerances and ordering requirements are set, and verify a dimension or size against the registered SHS and RHS dimensions charts. The thematic steel size charts pillar ties this member to the wider material/coating/market continuity for reciprocal discovery.
Verification & misuse controls
Separate the product, the evidence and the documents
Standard conformity, MTC/test evidence, dimensional inspection, coating/finish evidence, commercial documents and destination-dependent documents are kept apart so nothing is implied that is not evidenced. No certificate is implied without a verified record.
Documentation groups
- Standard conformity & MTC — chemistry and mechanical minimums against the governing edition and grade, with heat/lot traceability. Never an unsupported certificate.
- Dimensional & test evidence — gauge record, outside dimension, wall, length, surface and any mechanical test, with its basis, requested explicitly.
- Commercial & destination documents — invoice, packing list, origin/transport and customs inputs agreed per the Incoterm and the destination.
Common input errors and when engineering review is required
- Mixing unit systems — outside in mm, wall in inches, length in m. Keep one unit system across the line.
- Treating EN 10219 and EN 10210 as interchangeable — the sources note square/rectangular sectional properties are not equivalent. Confirm the route and edition.
- Reading a chart as stock or design compliance — a dimensional reference is not availability, wall-standard table, grade, finish or final design compliance; engineering review is required for member sizing and adequacy.
Product decision handoff
Registered choices that change the dimension buy
Shape, material, grade, standard and application each change the Hollow Section Dimensions Chart procurement. Compare the registered choices and their compatibility boundaries before you finalise the specification — then move the resolved requirement into the RFQ.
Compatibility boundaries
Compare, then finalise the registered route
The dimension complicates only within a stated shape, standard, grade, material and application. Compare a cold formed type route where geometry changes connection/fabrication, a stainless material route where the material/finish is explicit, an ASTM A1085 grade path where the mechanical/MTC requirement is fixed, and a registered application or industry route where the use case changes the requirement — then freeze the specification.

What the source actually proves that changes the Hollow Section Dimensions Chart decision
A source-scope checkpoint with buyer implication and an explicit non-equivalence/compliance boundary. The BSI EN 10219 resource is scoped to cold formed welded steel structural hollow sections and is a scope/index source — not a substitute for the purchased standard text and not an endorsement.
British Standards Institution — BS EN 10219 series
Official primary source · reviewed for scope
What does the primary source actually prove that changes the buyer decision for Hollow Section Dimensions Chart? The BS EN 10219 series is scoped to cold formed welded steel structural hollow sections and separates technical delivery conditions from tolerances, dimensions and sectional properties. Use the source to validate the scope and the questions that must be fixed in the RFQ — and route numeric details to the current licensed standard or verified order documents, never to a chart read by memory.
Buyer implication: Use the source to validate scope and the questions that must be fixed in the RFQ for Hollow Section Dimensions Chart; do not convert the source into unsupported stock, compliance, performance or logistics claims.
Scope: Cold formed welded steel structural hollow sections; the series separates technical delivery conditions from tolerances, dimensions and sectional properties. Limitations: The public BSI series page is a scope/index source rather than a substitute for the purchased standard text. Do not assume EN 10219 dimensional properties are interchangeable with EN 10210; BSI notes that square/rectangular sectional properties are not equivalent.
Evidence-led buyer advantages
A concern, answered with evidence, becomes an outcome
Each common buying concern for Hollow Section Dimensions Chart is met with a verifiable behaviour, not a promise. The result is a specification a buyer can audit before it becomes an order.
Buyer concern
Incomplete dimension triggers clarification
Every dimension field — shape, outside/side dimension, wall, length, tolerance, unit — is an explicit input with a stated method.
A single, complete RFQ that yields an apples-to-apples quotation instead of iterative clarification rounds.
Buyer concern
A chart taken as stock
Reference values are separated from actual stock, price, lead time, origin and certified shipment data; availability is confirmed, never padded.
A firm expectation that availability and lead time are confirmed at quotation, not assumed from a chart.
Buyer concern
Theoretical weight read as invoiced
Unit weight implied by a cross-section is labelled theoretical; actual shipment weight is confirmed against the MTC and shipping records.
An invoiced weight that matches the verified declaration, not a theoretical figure.
Buyer concern
EN 10219 and EN 10210 confused
The standard families are stated as distinct routes with a non-equivalence boundary on square/rectangular sectional properties.
A dimension quoted against the correct route and edition, without an interchanged value.

Formula / method in practice
The unit-weight reference and its boundary
A focused, decision-useful view of the reference derivation used in the tool — no repetition of the method section, only what changes the buyer decision.
Where a reference unit weight is derived for a hollow section, it is a theoretical value computed from the stated cross-section (outside dimensions and wall) under a stated standard and unit system. That value is presented as a reference for check, never as the invoiced weight. The actual shipment weight is confirmed against the mill certificate and the shipping records, and the wall-standard table, tolerance and any derived section property are read from the current licensed standard — never invented on the page.
Decision rule: use the reference to cross-check an RFQ line, and block the publication of any numeric weight, wall or section-property figure that is not sourced to the governing standard, project specification or verified mill/MTC value.
Worked examples — evidence-safe
How the examples stay decision-useful without inventing values
The worked examples above are the proof that a dimension becomes an RFQ line without any fabricated number — each one names the input, the method and the verification step.
- Labelled hypotheticals. Each example is clearly labelled as a hypothetical input; none implies stock, a company project or a confirmed order.
- Every field is explicit. Shape, standard/edition, outside dimension × wall × length, unit and tolerance are carried — nothing is inferred from the product name.
- Verify, don't invent. Where a value cannot be sourced — a wall, a section property, an actual weight — the example marks it "to be confirmed" rather than filling an estimate.
