1、方管產品說明

1. Product Description of Square Tube

方管是一種空心方形的截面輕型薄壁鋼管，也稱為鋼制冷彎型材。它是以Q235熱軋或冷軋帶鋼或卷板為母材經冷彎曲加工成型后再經高頻焊接制成的方形截面形狀尺寸的型鋼。熱軋特厚壁方管除壁厚增厚外情況,其角部尺寸和邊部平直度均達到甚至超過電阻焊冷成型方管的水平。

Square tube is a lightweight thin-walled steel pipe with a hollow square cross-section, also known as a steel cold-formed profile. It is a square section shaped steel made from Q235 hot-rolled or cold-rolled strip or coil as the base material, which is cold bent and formed, and then high-frequency welded. Except for wall thickness increase, the corner size and edge flatness of hot-rolled thick walled square pipes reach or even exceed the level of resistance welding cold formed square pipes.
