Stainless steel square pipes for construction structures

Square steel pipes made of architectural structural stainless steel that allow for a variety of surface finishes and can also serve as finishing materials.

Stainless steel materials for construction structures were standardized as "JIS G 4321" in 2000, and in 2002, due to the revision of the Building Standards Act, they became usable as construction structural members, similar to ordinary steel (iron). The types of steel that can be used as construction structural members are three: SUS304A, SUS316A, and SUS304N2A. Additionally, there are H-shaped steel, equal leg angle steel, channel steel, round steel, circular steel pipes, and square steel pipes. The square steel pipes are manufactured by cold forming, so their type designation is "SUS304A-C." 【Features】 ■ Excellent corrosion resistance, improving building lifespan and simplifying maintenance ■ Various surface finishes are possible, allowing them to serve as finishing materials ■ Minimal reduction in strength due to heat, while exhibiting high toughness at low temperatures ■ Large plastic deformation capacity, rich in toughness, enhancing the seismic resistance of buildings *For more details, please refer to the PDF materials or feel free to contact us.
