Quality assurance:
With advanced machine, We can check chemical component, mechanical property, water pressure, etc
Regular inspection: diameter, wall thickness, length, welding range, surface, etc
Application: Black welded steel pipe
1. Application in the construction field:
Structural use: Cold-formed square pipe is often used in building structure columns, beams, trusses and other load-bearing components. Its high strength and excellent toughness ensure the safety of buildings in the face of natural disasters (such as earthquakes, wind disasters, etc.).
Decorative use: Cold-formed square pipes can be made of various shapes and patterns through cold-formed forming for the decoration and beautification of building facades.
2. Mechanical manufacturing applications:
Structural parts: Cold-formed square pipes are used for structural parts of mechanical equipment, such as bases, supports, etc. Its dimensional accuracy and strength make the mechanical equipment more stable and durable.
Guide rails: Cold-formed square tubes are used to manufacture guide rails, such as slides, guide rods, etc., to maintain the accuracy of the movement of mechanical parts.
