Where to buy

Producers of Angles – local mills first. Buy direct from the mill for large tonnages, or through a steel distributor / stockist for small quantities and cut lengths.

Buying checklist
  • Specify the section designation, product standard and steel grade exactly (e.g. "L8x8x1 – ASTM A6/A6M – A36 (36 ksi)").
  • Ask for mill test certificates (EN 10204 type 3.1 or equivalent) traceable to the heat number.
  • Sections from another standard system are not automatically equivalent – have the engineer approve any substitution.
  • Check availability, minimum order quantity, stock lengths, lead time and delivery terms with the mill or distributor.
