Steel Billet · Size

100×100 mm Steel Billet

Treat 100×100 mm as the nominal square cross-section, then agree side limits, corner geometry, straightness and length with the receiving mill. Select the grade and quality plan independently of the size.

Nominal square size does not establish actual area, grade, stock availability or a universal tolerance. Rounded corners and actual dimensions affect mass.

State these before the order

  • The agreed upper and lower side limits, and where they are measured.
  • The corner geometry and shape limits, not assumed sharp corners.
  • The straightness limits that apply to the delivered length.
  • The usable cut length and the receiving-equipment envelope.
  • The grade and quality plan released on a separate schedule.

Qualify the charge

Decide whether this is the right billet route

The charge section decides what the mill has to accept. Each row names the decision, why it matters at this stage, and what you must be able to state before the order is released.

Enquiry builder

100×100 mm Steel Billet — enquiry builder

Capture the decisions below, prepare a review summary and copy it to the billet RFQ. Approve the full 100×100 mm billet envelope and measured-mass basis before order release.

1. Enter the specification

Fields marked * are required. Use mm for cross-section dimensions and tolerances, m for length, and an explicit quantity unit. Enter positive quantities and lengths; piece counts must be whole numbers. If a design detail is unresolved, describe the decision needed rather than guessing a grade.

Complete the specification to prepare a review summary.

2. Review summary

Your prepared specification will appear here. No enquiry has been sent.

This builder prepares your enquiry locally. Nothing is submitted from this page, and no personal data is collected here — the steel-billet RFQ owns contact collection.

Acceptance basis

Put the acceptance basis on the order

Nominal square size does not establish actual area, grade, stock availability or a universal tolerance. Rounded corners and actual dimensions affect mass. Each row names the applicability limit, the evidence to request and the action that closes it.

Documents & inspection

Documents that support 100×100 mm steel billet

Record both side dimensions and the agreed shape checks. Keep billet size inspection separate from heat chemistry and internal-quality acceptance.

Application paths

Follow the operating duty to the right specification

The drawing and service envelope govern acceptance. These paths address different purchasing decisions; an application label does not approve a material.

Small-section mill input

Confirm the nominal size fits the approved charge schedule.

Rebar-production input

Use only the grade and section accepted by the rebar mill.

Commercial scope

Compare offers on the same delivered scope

State pieces, length and mass basis separately. Compare usable delivered material after any agreed conditioning or end removal, rather than relying on ideal square mass.

Ask the supplier for

  • The side limits offered against the nominal 100 mm section.
  • The shape, corner and straightness schedule that applies.
  • The usable cut length and the cut-end condition.
  • The offered mill and origin.
  • Commercial validity and stated exclusions.

State on the enquiry

  • Whether the quantity is priced by pieces, length or mass.
  • The payable quantity basis and the agreed weighing method.
  • The Incoterm rule with its named place and edition.
  • Who unloads at the receiving point.
  • The requested delivery window.

Ask for the offered mill and origin, billet schedule, quantity basis, processing scope, packing, commercial validity and exclusions. State the Incoterm with its named place and edition, who unloads, and the requested delivery window. Price, availability, production allocation, transport feasibility and dates require written confirmation.

Coordinate an export enquiry

Expert insight

Expert Insight: Can a chemistry reference set the charge envelope?

A chemistry framework such as SAE J403 does not define this nominal square's receiving envelope.

Buyer implication: Release geometry and grade on separate order schedules.

Method: Review of the primary publisher's public scope; procurement implications are editorial analysis. Applicability: Chemistry-reference boundary. Limit: The ideal geometry table is arithmetic, not a standard tolerance or mill mass table.

Evidence boundary

  • Method and scope cited from the primary publisher.
  • No tolerance or mechanical value is stated on this page.
  • The ideal table is labelled arithmetic, not a mill mass table.
  • No density, certificate or test report is asserted as held.

Acceptance controls

Side dimensions

Agreed upper/lower limits and measurement method.

Specify where and how each side is measured.

Shape and corners

Approved shape schedule and actual checks.

Agree limits rather than assuming sharp corners.

Length and mass

Cut-end schedule and agreed weighing basis.

From specification to receipt

Close each decision before releasing the order

Four stages carry the order from engineering release to receipt. Each names the owner, the required input, the evidence produced and the risk if the item stays open.

Questions before ordering

Questions before you place the billet order

Four questions that decide whether a nominal 100×100 mm offer is comparable.

Are the corners assumed sharp?

Only in the labelled ideal geometry reference, not in delivered acceptance.

Is a standard tolerance included?

No. Agree the applicable limits and measuring method.

Is a fixed kg/m value promised?

No. Density and actual geometry are not assumed.

Can 130 mm be substituted?

Only after the mill approves the revised charge.
