GNEE is a professional manufacturer of carbon steel and mild steel pipes. Its EN S355K2H square tube sizes range from 10mmx10mm to 800mm, with wall thicknesses from 1mm to 40mm. Length can be customized. Tensile strength ranges from 510M Pa to 680M Pa.
S355K2H structural steel pipe is commonly used in the structural and civil engineering and construction fields. It is a low-alloy high-strength steel with good shape and impact toughness. It is mainly used to manufacture bridges, ships, vehicles, boilers, high-pressure vessels, lifting and transportation mechanisms, large steel products, etc. Using it instead of ordinary carbon steel greatly reduces the weight of the structure and ensures the use of reliable, durable materials.
GNEE can provide seamless and welded EN standard S355K2H structural square steel pipes.
