AS / NZS 1163 C250 / C350 / C450 L0 RHS (Rectangle Hollow Section), CHS (Circular Hollow Section) and SHS (Square Hollow Section
UNION VICTORY export and stock AS/NZS 1163 cold-formed steel hollow section. Specifies the requirements for the production and supply of cold-formed, electric resistance-welded, steel hollow sections used for structural purposes. It considers three strength grades, with or without impact properties, that are suitable for welding.
AS/NZS 1160 C250, C350, C450L0(GR250/GR350/GR450) ERW/LSAW steel pipes are mainly used for structural purpose. We export more than 10,000 tons AS/NZS 1160 C250/C350/C450 welded circular hollow section/steel pipes to Australia and New Zealand.
