Buying checklist
  • Specify the section designation, product standard and steel grade exactly (e.g. "HSS10.750x0.500 – ASTM A500/A500M").
  • 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.
