introduction
Stainless Steel Hollow Square Tube is a hollow square-section steel tube made of stainless steel, which is widely used in building structures, decoration design, industrial equipment, and other fields.
feature
Strong structure
Stainless Steel Hollow Square Tube uses automated welding equipment to ensure uniform and dense welds and high overall structural strength. The tensile strength of its 304 material reaches ≥520MPa, which is suitable for engineering structures requiring high-strength load-bearing and has excellent pressure-bearing and deformation resistance.
Reasonable weight
On the premise of ensuring strength and durability, the hollow structure of Stainless Steel Hollow Square Tube effectively reduces its weight, which can reduce the material consumption by about 30%-50% compared with solid steel, which is conducive to engineering weight reduction and transportation cost optimization.
Excellent corrosion resistance
Due to the high proportion of chromium and nickel in its stainless steel material, the Stainless Steel Hollow Square Tube has excellent corrosion resistance in humid, acidic, alkaline, or salty environments. The corrosion resistance of 316L material is particularly outstanding and is widely used in marine environments and chemical plants. Its service life is about 2-3 times longer than ordinary carbon steel pipes.
