Introduction to Welded Pipe Stainless Steel Square Tube
Welded pipe stainless steel square tube is a type of hollow steel section with a square cross – section. It is made by welding stainless steel strips or plates together. Stainless steel, known for its excellent corrosion resistance, high strength, and aesthetic appeal, makes these square tubes highly versatile in various industries. They are widely used in construction for building frames, handrails, and structural supports; in the automotive industry for exhaust systems and chassis components; and in the furniture and decoration industry for creating modern and durable pieces. The welding process can be either electric resistance welding (ERW) or submerged arc welding (SAW), each offering different advantages in terms of production speed, quality, and cost.
