Weathering steel welded structural pipe
Steel Grades: Gr.B (耐候级)
Commonly used in exposed steel structures of buildings, including columns, beams, and truss members, as well as decorative components such as curtain wall framing, canopies, and entrance frames. Due to its regular square and rectangular cross-sections and resistance to atmospheric corrosion, it is also used in landscape engineering structures, outdoor facility frames, pergolas, and railing supports. Suitable for architectural and decorative applications exposed outdoors, emphasizing lines and a

EN 10219 (耐候级)
Weathering steel welded structural pipe
Steel Grades: S235J2W, S355J2W, S355K2W
Widely used in outdoor steel structures such as columns, beams, and trusses, as well as exposed components such as curtain wall joists, railings, canopies, and landscape pergolas. With its regular hollow cross-section, good toughness, and resistance to atmospheric corrosion, it is suitable for buildings and municipal structures exposed to wind and rain. It reduces the need for painting and maintenance, and is commonly found in scenarios where a rust-colored appearance is desired, such as walkway
