Standards reference

Standards and finish references can be reviewed by project requirement

  • Steel grating can be reviewed according to drawings and standards such as YB/T 4001.1, ANSI/NAAMM MBG 531 or BS 4592 when required.
  • Hot-dip galvanizing can be specified according to ISO 1461 or ASTM A123/A123M when a defined zinc coating reference is needed.
  • Platform, stair and access projects may refer to ISO 14122 or local safety requirements for walking surfaces and guardrail interfaces.
  • Final specification should follow project drawings, load notes, local codes and buyer approval documents.
