Square steel pipe is a common metal pipe with a square or rectangular cross-sectional shape. It is usually made by hot rolling or cold drawing and can be used in various industrial fields and construction projects. Square steel pipe is mainly made of materials such as carbon steel, alloy steel and stainless steel, and has good mechanical properties and corrosion resistance.
Square steel pipe can be divided into two production processes: welding and seamless. Welded square steel pipe undergoes welding process during production, while seamless square steel pipe is manufactured by processing seamless steel pipe. Seamless square steel pipe has smooth surface and precise size, which is suitable for engineering projects with higher requirements, while welded square steel pipe is suitable for general engineering projects.
Square steel pipe is widely used in building structure, machinery manufacturing, bridge construction, automobile manufacturing, petrochemical and other fields. In the field of construction, square steel pipe is often used to build frames, support structures and piping systems. In the field of machinery manufacturing, square steel pipe can be used to manufacture various parts and mechanical equipment. In the field of petrochemical, square steel pipe can be used to transport liquids and gases.
In general, square steel pipe is a kind of metal pipe with diverse functions and wide applications. It has excellent performance and reliable quality and plays an important role in various industries.
