Hollow Section Size Chart
Use this hollow section size 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.
To quote Hollow Section Size Chart correctly you must fix the shape, the governing standard and edition, the outside dimension range and wall, the grade or material and finish, the quantity and destination — and you must separate the reference size from availability, MTC and shipment data. State the unit system and any documents so the RFQ line is technically complete the first time.
- Shape + standard/edition first
- Unit system disclosed
- Reference ≠ stock, MTC, or shipment
- Copyable RFQ to commercial

Hollow Section Size Finder
Filter a hollow-section size reference by shape, standard family, unit system, dimension range and wall, align it to a registered product route, and hand a complete copyable RFQ line to commercial.
Size finder result
Shape and governing standard required
A hollow-section size 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 size finder can align the reference the value answers to. A size value alone does not establish wall, grade, material, finish or final design compliance.

Method & source
Method, formula and data conditions
This page is a reference to a dimensional size basis, not a substitute for the current standard text or a supplier-certified shipment record. The method below states how a reference size is read and where its limits are.
Reference method
A hollow-section size is read as shape + outside (side or diameter) dimensions + wall, under one unit system, against a named standard family and edition. The reference is theoretical/dimensional: it records what the section is, not that it is stocked or shipped.
Units and rounding
Keep outside dimensions, wall and length in one unit system — metric (mm) or imperial (in). Rounding and tolerance limits are set by the governing standard/edition, the project specification or the mill certificate; they are never assumed from a chart value.
Source hierarchy
The governing standard and edition come first, then the project specification, then a verified mill/MTC value. Reference values published here are theoretical; actual shipment weight, stock, MTC, inspection and commercial terms come only from a quotation/order evidence.
Boundary. A dimensional reference on this page must not be taken as proof of stock, final design compliance, mechanical performance, coating/finish or delivery. Those fields are confirmed with the current standard, the project specification or a supplier-certified document — never inferred from a chart.
Worked examples
Procurement-grade worked examples
Three hypothetical, clearly labelled examples show how to turn Hollow Section Size Chart inputs into a complete, copyable RFQ line. They teach method; they are not company projects and imply no stock.
Hypothetical example
SHS 100 × 100 × 4 mm · EN 10219
Standard: EN 10219 (cold formed)
Input: Square hollow section for a column brace; 100 × 100 mm, wall 4 mm, length 6000 mm, metric, 40 lengths, Jebel Ali UAE.
RFQ line: Hollow section, SHS 100 × 100 × 4 mm × 6000 mm, EN 10219 (edition to be confirmed), metric; 40 lengths, destination Jebel Ali UAE — dimensions only; grade/material, finish, stock and final design compliance verified separately.
Shows how a complete size line (shape, outside side, wall, length, unit, standard) transfers into the RFQ in one consistent unit system.
Hypothetical example
RHS 200 × 100 × 8 mm · ASTM A500
Standard: ASTM A500 Grade C
Input: Rectangular hollow section with directional stiffness; 200 × 100 mm, wall 8 mm, length 8000 mm, imperial, 20 lengths, Dammam Saudi Arabia.
RFQ line: Hollow section, RHS 200 × 100 × 8 mm × 8000 mm, ASTM A500 Grade C (edition to be confirmed), imperial; 20 lengths, destination Dammam Saudi Arabia — dimensions only; grade/material MTC, finish, stock verified separately.
Shows how carrying the standard/grade along with dimensions prevents a grade or mechanical-property requirement from being inferred from the size alone.
Hypothetical example
CHS Ø 60.3 × 3 mm · EN 10210
Standard: EN 10210 (hot finished)
Input: Circular hollow section for a handrail support; outside diameter 60.3 mm, wall 3 mm, metric, quantity to confirm, destination to confirm.
RFQ line: Hollow section, CHS Ø 60.3 × 3 mm, EN 10210 (edition to be confirmed), metric; quantity and destination to confirm — dimensions only; grade, finish, stock and final design compliance verified separately.
Shows the case where quantity and destination are not yet fixed: the RFQ carries the size and standard rather than a fabricated delivery or price.
Standards & sizes
Standards and tolerance context
A hollow-section size is decision-useful only when its standard family, edition, tolerance basis and unit system are fixed. The rows below are reference/dimensional values; the named standard or project specification sets the limits, and the mill certificate confirms actual shipment data.
Reference size rows
| Size | Value | Basis note |
|---|---|---|
| SHS 100 × 100 × 4 mm | Reference row (dimensional) | Square hollow section under a cold-formed or hot-finished route; outside side × wall. Verifies the nominal size against the governing standard/edition before RFQ. |
| RHS 200 × 100 × 8 mm | Reference row (dimensional) | Rectangular hollow section with directional stiffness; outside sides × wall. Confirms the size is a dimensional reference, not a stock statement. |
| CHS Ø 60.3 × 3 mm | Reference row (dimensional) | Circular hollow section / round tube; outside diameter × wall. The governing route and edition determine the tolerance and section-property fields. |
| Wall / thickness tolerance | Per governing standard/edition | Tolerance and dimensional limits are set by the named standard and edition, the project specification or the mill certificate — never assumed. |
| Unit weight (reference) | Theoretical / reference value | Any stated unit weight is a dimensional reference under a stated basis; actual shipment weight is supplier-certified with the MTC. |
Evidence warning. These are reference/dimensional rows. A specific numeric section-property, tolerance, unit weight or mechanical value requires the current licensed standard, the project specification or a verified mill/MTC value — otherwise the row is blocked from publication.

Evidence controls
Verification and misuse controls
Separate the fields a size chart can and cannot establish. Standard conformity, MTC/test evidence, dimensional inspection, coating/finish evidence, commercial documents and destination-dependent documents are distinct — never imply a certificate that is not evidenced.
Standard conformity
Fixed by the named standard and edition
Conformity is confirmed against the governing standard/edition and, where required, the project specification; it is not established by a size chart.
MTC / test evidence
Supplier-certified with the MTC
Chemistry, mechanical properties, heat treatment and test results come from the mill/test certificate, never from a reference size.
Dimensional inspection
Against stated tolerance
Outside dimensions, wall, straightness and end tolerances are inspected against the standard/edition tolerance basis; a reference value is not an inspection record.
Coating / finish evidence
Documented where required
Galvanizing or other finishes require their own stated coating weight/method and document evidence; do not infer finish from a bare size reference.
Commercial documents
Quotation / order records
Commercial invoice, packing list, origin and Incoterm come from the commercial records you receive, not from the chart.
Destination-dependent documents
Per destination and order
Import, origin and destination-specific documents are confirmed against the actual order and destination before quotation.
Engineering review
Engage the design/engineering team when the chosen size must satisfy a load, deflection or connection requirement. A size chart records geometry; final design compliance and performance are confirmed by the engineer, the governing standard and the evidence set — never by a chart alone.
Request technical RFQ supportProduct handoff
Connect the size to a registered product route
After you fix the Hollow Section Size Chart reference, choose the geometry, material, grade, standard and application routes that match the order. Each choice changes the RFQ fields, so confirm the compatibility boundary before you freeze the specification.
Registered selection routes
- Where circular geometry changes connection and fabrication, compare the circular hollow section supplier route.
- State the material and finish explicitly on the galvanized hollow section supplier route.
- Confirm mechanical-property and MTC requirements on the astm a500 grade c hollow section grade route.
- Check whether the size requirement changes for hollow section for solar structures.
- Check whether the size requirement changes for hollow section for handrails.
- Add industry-specific procurement context on the hollow section for manufacturing route.

What the primary source actually proves
A decision aid measured against the cited primary source — not a named-person endorsement and not an endorsement by the source organization.
British Standards Institution — BS EN 10219 series
Primary source: https://landingpage.bsigroup.com/LandingPage/Series?UPI=BS+EN+10219
Information date: 2026-09-07 verification
Scope
Cold formed welded steel structural hollow sections; the series separates technical delivery conditions from tolerances, dimensions and sectional properties.
Limitations & non-equivalence boundary
- The public BSI series page is a scope/index source, not 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.
Buyer implication
Use the source to validate scope and the questions that must be fixed in the RFQ for Hollow Section Size Chart; do not convert the source into unsupported stock, compliance, performance or logistics claims.
Why a verified size basis
Evidence-led buyer advantages
Each card maps a real buyer concern to verifiable evidence or capability and then to a practical procurement outcome. No unsupported superiority claims.
Repeated clarification when a size RFQ lacks the governing standard
Evidence: A size chart resolves shape and standard first; edition, tolerance, grade, material, finish and stock are stated as separate fields that the RFQ must fix.
Outcome: The buyer submits one complete size line and the quotation carries a verified dimensional basis the first time.
A reference value mistaken for stock, MTC or shipment data
Evidence: The size finder separates 'size exists in a verified reference' from 'Noor Deira availability', and the visible copy labels weights as theoretical/reference values.
Outcome: Buyers verify availability and evidence separately before scheduling, so the quotation matches the actual shipment and document set.
EN 10219 and EN 10210 values treated as interchangeable
Evidence: The source scope and the visible boundary state that cold-formed and hot-finished routes have non-equivalent sectional properties and must be confirmed.
Outcome: The RFQ anchors to one named route and edition, preventing apples-to-oranges quotations and a wrong size read.
Missing unit system or incomplete dimension set in the RFQ
Evidence: The tool captures shape, standard/edition, outside dimension range, wall, application, quantity, destination, Incoterm and delivery in one unit system.
Outcome: A complete, copyable RFQ line hands to the registered hollow-section RFQ target without losing the product context.

Method resource
How a size reference is read
A decision-useful, evidence-safe method note specific to Hollow Section Size Chart.
Read and state a hollow-section size
- Fix the shape: square (SHS), rectangular (RHS) or circular (CHS / round tube) hollow section.
- Fix the governing standard family and edition — cold-formed (for example EN 10219) or hot-finished (EN 10210), or the ASTM A500/A1085 route.
- State the outside (side or diameter) dimensions and wall under one unit system.
- Left values are entries for the RFQ: the tolerance, section-property and unit-weight fields are set by the standard/edition, the project specification or the mill certificate, not by the chart.
Boundary. This method confirms how to read the size reference; it does not certify chemistry, mechanical properties, finish, stock or delivery. Route numeric details to the current licensed standard or verified order documents.
Example resource
One complete worked size line
A hypothetical, clearly labelled example showing input, method, result, interpretation, decision impact and the verification step.
Input
SHS 100 × 100 × 4 mm × 6000 mm, EN 10219 (edition to be confirmed), metric, 40 lengths to Jebel Ali UAE.
Method & result
Hollow section, SHS 100 × 100 × 4 mm × 6000 mm, EN 10219 (edition to be confirmed), metric; dimensions only.
Interpretation: the size line is complete for an RFQ; it records the reference size, not stock or compliance.
Decision impact: the quotation is quoted against a verified dimensional basis the first time, avoiding clarification.
Verification step: confirm grade/material, finish, tolerance and stock separately with the commercial team and the MTC before scheduling.
