Hollow Section Weight Chart
Use this hollow section weight 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 / mass basis
- Wall & tolerance basis
- Theoretical vs certified
- Verify before RFQ
Price on request · theoretical/reference values are separated from supplier-certified stock and shipment data; verify wall, grade/material, finish and design compliance separately
Working technical tool
Hollow Section Weight Reference Calculator
A reference calculator that turns a hollow-section shape, standard family, unit system, dimension, length and quantity into a reference unit-weight field and a copyable RFQ line. It never invents a weight: it validates the inputs, echoes only verified fields, labels any calculated mass as theoretical/reference, 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 weight 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 route — plus the unit-weight basis (as-welded vs design basis where the standard distinguishes them) and whether the reference table supports the calculation. Select both so the chart identifies which reference the value answers to. A dimensional line alone does not establish wall, grade, material, finish or final design compliance.
Governing standard & edition
Every weight is a reference value under a stated standard family and edition — EN 10219 (cold formed), EN 10210 (hot finished), or the ASTM A500 route. The chart names its source and unit-weight basis; it never invents a value.
Unit & mass coherence
Outside dimensions, wall, length and the mass basis are kept under one unit system — metric (mm / kg) or imperial (in / lb) — converted consistently so no false precision is created between shape, wall, length and unit weight.
Theoretical vs certified weight
Unit weight implied by a cross-section is theoretical until confirmed against the current standard/table and the mill certificate. Actual shipment weight is supplier-certified and reconciled to the shipping records.
Publication blocker
A specific numeric weight, total mass or 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 weight reference is derived, and where it stops
The chart states its method, unit system, source hierarchy, edition/date, assumptions, applicability and limitations. It separates theoretical/reference weights from supplier-certified values and blocks the publication of any value without a source.
Method
- Unit weight keyed to a stated standard family and edition and a mass/unit basis — never an anonymous chart.
- One coherent unit system (metric mm / kg, or imperial in / lb) across outside dimension, wall, length and mass.
- Any calculated total mass is labelled theoretical/reference unless the governing standard or table supports it; actual shipment weight comes from 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.
- Theoretical weight is not stock, price, grade, finish, wall-standard table, actual shipment weight 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, total mass 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 and unit basis to an RFQ line, without inventing a weight
Each example is a clearly labelled hypothetical input that shows how to turn a hollow-section dimension and stated unit basis into a complete RFQ line. None of these reflect stock or a company project; each teaches the input-to-RFQ method and the point where the weight must be verified.
Hypothetical example
SHS 100 × 100 × 4 mm
Input: Square support member; outside 100 × 100 mm, wall 4 mm, length 6000 mm, quantity 120 pcs, metric (mm / kg).
RFQ line: Hollow section, SHS 100 × 100 × 4 mm × 6000 mm, EN 10219 (edition to be confirmed), unit metric (mm / kg); unit weight (reference) and total mass confirmed against the standard table/MTC — wall-standard table, grade, finish and stock verified before RFQ.
Shows the exact shape, outside dimensions × wall × length, quantity and unit basis in one RFQ line so no inferred diameter, wall or weight 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; unit weight and any section-property field verified against a current source before use — do not read an axial vs transverse weight/property from a memory chart.
Shows how an axial vs transverse section-property distinction, and the project weight basis, 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 and wall to be confirmed against standard, imperial (in / lb).
RFQ line: Hollow section, round (CHS), ASTM A500 series (edition to be confirmed), outside and wall to be confirmed in imperial; dimensions and unit weight only — grade, mechanical basis, stock and actual shipment weight verified separately.
Shows the case where the dimension and weight are not yet fixed: the RFQ carries the standard and the “to be confirmed” fields rather than an invented diameter or weight.
Standards & weight 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, unit-weight basis 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 |
| Unit weight (reference) | Theoretical per cross-section and mass basis; actual weight is supplier-certified | Current standard/table or mill/MTC value | Theoretical reference only; actual weight from MTC and shipping records | Request actual weight declaration with the MTC |
| Total mass estimate | Theoretical/reference unless supported by the governing standard/table | Current standard/table, project specification or MTC | Blocked or labelled theoretical unless a verified basis is supplied | Request the verified mass basis with the quotation |
| 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 or weight-invoice value. Any gauge, weight, mass, dimension, tolerance, radius or section-property figure is confirmed against the governing standard/edition, the project specification and the mill certificate before quotation.

Registered technical references
Anchor the standard, the size and the weight before RFQ
Confirm the JIS G3466 standard route where scope, tolerances, testing and ordering requirements are set, and verify a dimension or size against the registered hollow-section size chart and the CHS dimensions chart before you fix the weight basis.
Verification & misuse controls
Separate the product, the evidence and the documents
Standard conformity, MTC/test evidence, dimensional and weight inspection, coating/finish evidence, commercial documents and destination-dependent documents are kept apart so nothing is implied that is not evidenced. No certificate or actual-weight figure is implied without a verified record.
Documentation groups
- Standard conformity & MTC — chemistry and mechanical minimums against the governing edition and grade, with actual-weight declaration and heat/lot traceability. Never an unsupported certificate.
- Dimensional & weight evidence — gauge record, outside dimension, wall, length, unit weight 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, with the actual-weight basis.

Common input errors and when engineering review is required
- Mixing unit or mass systems — outside in mm, wall in inches, length in m, weight in a different unit. Keep one unit and mass basis 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, actual weight or design compliance — a weight reference is not availability, wall-standard table, grade, finish, invoiced weight or final design compliance; engineering review is required for member sizing and adequacy.
Product decision handoff
Registered choices that change the weight buy
Shape, type, material, grade, standard and application each change the Hollow Section Weight 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 weight reference only holds within a stated shape, type, standard, grade, material and application. Compare a hot-finished type route where geometry changes connection/fabrication, a weathering-steel material route where the material/finish is explicit, and an STKR490 grade path where mechanical-property and MTC requirements are fixed — then check the frames, columns and construction application/industry routes before you freeze the specification.

What the source actually proves that changes the Hollow Section Weight Chart decision
A source-scope checkpoint with buyer implication and an explicit non-equivalence/compliance boundary. The ASTM A500/A500M-23 standard is scoped to cold-formed welded and seamless carbon steel structural tubing and is used here within that published scope — not as proof of stock, compliance, performance or logistics.
ASTM International — ASTM A500/A500M-23
Official primary source · reviewed for scope
What does the primary source actually prove that changes the buyer decision for Hollow Section Weight Chart? ASTM A500/A500M is scoped to cold-formed welded and seamless carbon steel structural tubing in round, square, rectangular and special shapes for structural uses. Use the source to validate that scope and the questions that must be fixed in the RFQ — and route numeric weight, grade, tolerance and ordering 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 Weight Chart; do not convert the source into unsupported stock, compliance, performance or logistics claims.
Scope: Cold-formed welded and seamless carbon steel structural tubing in round, square, rectangular and special shapes for structural uses. Limitations: The ASTM public abstract does not provide every grade property, tolerance or ordering detail; do not reproduce paywalled tables from memory. Project specifications can impose requirements beyond ASTM A500/A500M; verify the purchase order and the current licensed standard.
Evidence-led buyer advantages
A concern, answered with evidence, becomes an outcome
Each common buying concern for Hollow Section Weight 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 input triggers clarification
Every weight field — shape, outside/side dimension, wall, length, unit/mass basis, reference table, quantity — 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 or invoiced weight
Reference values are separated from actual stock, price, lead time, origin and certified shipment data; actual weight is confirmed with the MTC, never assumed.
A firm expectation that availability, lead time and the invoiced weight are confirmed at quotation, not read 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 weight 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 calculator — 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, unit system and mass basis. 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, mass, wall or section-property figure that is not sourced to the governing standard/table, 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 and unit basis become 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, quantity, unit and mass basis are carried — nothing is inferred from the product name.
- Verify, don't invent. Where a value cannot be sourced — a wall, a unit weight, a total mass — the example marks it "to be confirmed" rather than filling an estimate.
