Wholesale stainless square tube, quality deal

Stainless steel square tubes are hollow, square-shaped sections made from stainless steel, a corrosion-resistant alloy that contains a minimum of 10.5% chromium. This unique composition not only provides exceptional strength and durability but also ensures that the material can withstand harsh environmental conditions without succumbing to rust or corrosion. The square tube design offers a perfect balance of structural integrity and aesthetic appeal, making it an ideal choice for a wide range of applications.

Production process

Choose suitable stainless steel plates or strips as raw materials. Commonly used materials include 304, 316, etc.
Cutting:
Cut stainless steel sheets or strips into required width and length for subsequent forming.
Molding:
The cut stainless steel strip is rolled into a tube by cold or hot rolling. The strip is gradually formed into the shape of a square tube by a roller press.
Welding:
During the forming process, the edges of the square tube will be welded. Commonly used welding methods include TIG welding, MIG welding, etc. to ensure the strength and sealing of the weld.
Cooling:
After welding, the square tube will go through a cooling process to reduce the temperature and stabilize its shape.
Straightening:
Use the straightening machine to straighten the square tube to ensure its flat shape and accurate size.
Cutting:
Cut the formed square tube into required lengths to meet customers’ specific needs.
Surface treatment:
Carry out surface treatment on the square tube, such as pickling, polishing, sand blasting, etc., to improve its corrosion resistance and aesthetics.
Inspection:
Conduct quality inspection on finished products, including dimensions, weld quality, surface defects, etc., to ensure compliance with relevant standards.
Packing and Delivery:
Qualified square tubes will be packaged and ready to be shipped to customers.
