Square cold-formed hollow section steel is a section steel with square cross-section shape and size made of hot-rolled steel plate after cold-bending and then high-frequency welding. It is also called welded square steel pipe. The section steel has a stable production process and high precision, and can produce any cross-section pipe shape. The corner size and edge straightness of the square cold-formed hollow section steel reach or even exceed the level of cold-drawn square steel pipes.
Cold-drawn square steel pipe is formed by cold-drawn seamless steel pipe, also known as cold-drawn square steel pipe, cold-drawn square steel pipe has no weld seam, cold-drawn square steel pipe has high pressure resistance, cold-drawn square steel pipe has good comprehensive mechanical properties, cold and hot processing performance It has good corrosion resistance and good low temperature toughness.
