A widely used structural carbon steel specification for general fabrication and load-bearing applications.

Purchase to your specification

A36 for production and repeat supply.

Buying A36 for machining, forging, or component production? Send your dimensions, condition, and quantity per order. For repeat supply, include annual usage and release timing, or attach your existing RFQ.

Size & supply condition: State the diameter, length, and required condition. We confirm the available supply route against your order.
Finished to your requirement: Include production cutting, surface finish, tolerances, and any required heat treatment. Processing is reviewed with the material requirement.
Documentation & delivery: Specify mill certifications, testing, traceability, delivery date, and ship-to location so they can be included in the quote.

A grade name is the starting point. The governing specification, condition, dimensions, and testing define the material to be quoted.
