Technical resource · Dimensional reference
Choose the channel series first, then the full designation. Use the verified reference entries to compare depth, width, thickness and nominal kg/m, estimate a theoretical quantity and carry the exact profile into an enquiry.
The compact chart is a dimensional reference, not stock, a full rolling catalogue or a load-capacity table. UPE, UPN and PFC are not interchangeable solely because their depths match.
Working technical tool
Select one of the verified reference entries. This is a compact reference set, not a catalogue of available stock. Unlisted sizes require a producer table; do not interpolate.
Mass per metre is read from the cited producer entry. Nothing is estimated from the name.
Choose a reference entry, positive length and whole number of pieces.
The selected designation, dimensions, length and piece quantity populate the enquiry fields below. Grade and service approval remain separate.
Reference output
No reference result yet. The estimate applies a tabulated nominal mass per metre to the length and piece count you enter — it is a planning quantity, not a shipment weight.
No allowance for tolerances, coating, cutting waste or packing. Not a capacity check and not a measured shipment mass.

The calculated mass uses a nominal producer value. Confirm profile geometry, material grade, tolerances and design approval separately.
The specification you prepared is attached exactly as you entered it — designation, grade, standard edition, dimensions, quantity basis, destination and required documents. Unresolved items travel with it as open questions rather than being resolved on your behalf.
Price on request. A specification review is the first step — it is not a priced quotation, and no availability is confirmed at this stage.
Method, formula and data conditions
Read h, b, web thickness, flange thickness and mass per metre from the cited producer entry for the exact series. The formula is arithmetic; what the result means is a separate question.
Theoretical total mass (kg) = tabulated mass (kg/m) × piece length (m) × number of pieces. Every numeric field on this page carries its unit explicitly — metric throughout, and no value is converted silently.
mass (kg) = kg/m × m × pieces
Data checked . The source tables do not expose a separate revision date here.
These nominal values do not state availability or material compliance for any order.

Each comparison shows the entry, the arithmetic and the decision it changes. The values are the producer entries tabulated on this page — none of them establishes stock, capacity or a material grade.
UPE 200 is listed at 22.8 kg/m with a 80 mm width; UPN 200 is 25.3 kg/m with a 75 mm width. The common 200 mm depth does not establish equivalent geometry. Check connection and design approval before changing series.
For ten UPE 200 pieces at 6 m each: 22.8 kg/m × 6 m × 10 = 1,368 kg. Use this as a planning quantity and confirm the producer table, commercial mass basis and delivered quantity.
The PFC 260x90x35 reference has a tabulated mass of 34.8 kg/m. Do not treat the rounded designation component as a measured mass, or silently replace its series.
A theoretical total is an arithmetic result, not a commercial quantity. Ask whether pricing and dispatch use theoretical mass, measured mass or pieces before you compare two offers for the same channel.
Verified reference entries
The values below are a compact producer reference checked on 2026-10-15. Source-specific radii and full section properties remain in the cited tables; the ordered material and tolerances require their own acceptance basis.
| Specification decision | Applicability and limit | Evidence to request | RFQ action |
|---|---|---|---|
| Series identity | Same depth does not mean the same channel. | Exact producer designation and section drawing. | Record series, h, b, web and flange dimensions. |
| Grade and tolerance | A geometry table does not certify the material or permissible deviations. | Material certificate and applicable dimensional standard. | Add full grade, condition and critical tolerances. |
| Quantity basis | Nominal kg/m gives theoretical mass only. | Producer table and agreed commercial measurement method. | State length, pieces and invoice/dispatch mass basis. |
| Designation | Depth h / width b (mm) | Web / flange (mm) | Nominal kg/m | Order implication |
|---|---|---|---|---|
| UPE 100 | 100 / 55 | 4.5 / 7.5 | 9.8 | Parallel-flange series; confirm the full producer drawing. |
| UPE 200 | 200 / 80 | 6.0 / 11.0 | 22.8 | Do not substitute by depth alone. |
| UPN 200 | 200 / 75 | 8.5 / 11.5 | 25.3 | Tapered-flange series; check connection fit. |
| UPN 300 | 300 / 100 | 10.0 / 16.0 | 46.2 | Retain the UPN designation. |
| PFC 260x90x35 | 260 / 90 | 8.0 / 14.0 | 34.8 | Use tabulated mass for estimates, not the rounded name. |
| PFC 300x90x41 | 300 / 90 | 9.0 / 15.5 | 41.4 | Confirm offered geometry and tolerances. |

Documents and acceptance
Reject ambiguous series, mixed units and capacity claims drawn from mass alone. For a channel not listed here, request the producer's full geometry and mass entry before calculating.
| Control | What to examine | When and limits | Next action |
|---|---|---|---|
| Series identity | Exact producer designation and section drawing. | Before material acceptance; confirm feasibility and cost at quotation. | Record series, h, b, web and flange dimensions. |
| Grade and tolerance | Material certificate and applicable dimensional standard. | Before material acceptance; confirm feasibility and cost at quotation. | Add full grade, condition and critical tolerances. |
| Quantity basis | Producer table and agreed commercial measurement method. | Before material acceptance; confirm feasibility and cost at quotation. | State length, pieces and invoice/dispatch mass basis. |
| Heat and item identity | Mill test certificate linked to heat markings and packing list. | Before release and again on receipt; a sample certificate is not evidence for the shipped heat. | Request traceability through cutting, bundling and delivery. |

From reference to enquiry
The reference identifies a section. Which enquiry it belongs in depends on whether the designation resolved cleanly, needs another series checked, or needs an engineering decision first.
| Decision | Why it matters here | Before you enquire |
|---|---|---|
| Use the reference | The complete designation matches a listed producer entry. | Verify the offered mill table before ordering. |
| Verify another series | Only the nominal depth matches the drawing. | Compare width, web, flange and flange geometry. |
| Engineering review | A replacement is being selected for strength or stability. | Obtain a design check; dimensions and mass do not establish capacity. |

Responsibility
Four stages stand between a dimensional lookup and accepted material. Each one has an owner, a required input and a failure mode — none of them is resolved by the chart.
| Stage and owner | Required input | Evidence or output | Risk and next action |
|---|---|---|---|
| Engineering release — Buyer's design authority | Confirm the drawing's channel series and exact designation. | Approved specification and drawing revision | Unapproved substitution can change the design basis. Close the item before proceeding. |
| Offer review — Buyer and quotation team | Compare the producer geometry, grade and commercial mass basis. | Written technical exceptions and commercial scope | An unlisted exception can survive into the purchase order. Close the item before proceeding. |
| Material release — Mill, inspector and buyer as agreed | Check material identity and agreed dimensional evidence. | Accepted documents linked to the order items | Missing heat identity can make an otherwise correct section unacceptable. Close the item before proceeding. |
| Receipt and reconciliation — Receiving team | Reconcile designation, length and pieces rather than relying only on total tonnes. | Delivery record, item count and discrepancy record | Record any mismatch before the material is incorporated into work. Close the item before proceeding. |
Buyer questions
The answers below restate what the reference entries on this page actually support — and where the limit of a dimensional table begins.
No. Give the series and full designation, then verify width, web, flange and geometry. At a nominal 200 mm depth the cited UPE and UPN entries differ in width, web thickness, flange thickness and nominal mass, so the depth alone does not fix which channel your drawing calls for.
Only after the designer checks the full geometry, connection and structural implications. UPN is a tapered-flange series and UPE is a parallel-flange series; they are not interchangeable on a like-for-like basis, and a substitution that looks reasonable on depth can change the connection detail.
No. Capacity depends on the design, grade, restraint, orientation and loading. A nominal mass per metre is an arithmetic property of the section, not a statement about how it performs. Adequacy for a given design is determined by your engineer against the governing code.
It is theoretical. Confirm the commercial measurement basis, tolerances, processing and delivered quantity. The estimate applies a tabulated nominal mass per metre to the length and piece count you enter, and allows nothing for permissible rolling deviations, coating, cutting waste or packing.
Use the offered producer's verified table. Do not interpolate an unlisted designation. The reference set on this page is a compact selection rather than a rolling catalogue, so an absent size is a prompt to obtain the producer entry, not to derive one.
No. The source is a dimensional reference; the actual grade, mill, availability and documents require quotation confirmation. A geometry table does not certify the material or the permissible dimensional deviations, and the grade cannot be inferred from the section designation.
