Buying checklist
  • Specify the section designation, product standard and steel grade exactly (e.g. "PL20 (per 1000 mm width) – AS/NZS 3678:2016 – 250").
  • 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.
