1、方管产品说明

1. Product Description of Square Tube

方管是一种空心方形的截面轻型薄壁钢管，也称为钢制冷弯型材。它是以Q235热轧或冷轧带钢或卷板为母材经冷弯曲加工成型后再经高频焊接制成的方形截面形状尺寸的型钢。热轧特厚壁方管除壁厚增厚外情况,其角部尺寸和边部平直度均达到甚至超过电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.
