Stock statusMill indent
Typical lead time4 - 8 weeks mill indent

Weathering structural plate. Copper, chromium and nickel additions let a dense, adherent oxide patina form that seals the surface, so the structure can be left unpainted and the maintenance coating cycle disappears.

  • Self-protecting patina removes the painting cycle
  • Same 355 MPa yield and -20 C toughness as S355J2+N
  • Supplied in the normalised condition for weld consistency
  • Profile cut to architectural drawings
