Stainless Steel Square Welded Pipe
Stainless welded square pipes are commonly made of steel or steel strips that are welded after being curled and formed by a unit and a mold.
Stainless Rectangular Tube Description
Stainless steel welded square and rectangular tubes are processed and rolled from strip steel. Generally, the strip steel is unwrapped, flattened, crimped and welded into round tubes, then rolled into square tubes and cut to the required length.
Stainless steel welded square pipe is widely used in building structures, machinery manufacturing and other fields.

Stainless steel hollow section Applications:
1. Fluid Transportation: Due to its excellent corrosion resistance and high strength, stainless steel square tubing is widely used as a pipeline for transporting fluids such as oil, natural gas, water, coal gas, and steam.
2. Manufacturing Mechanical Parts and Engineering Structures: Because stainless steel square tubing is lighter in weight while maintaining the same bending and torsional strength, it is also widely used in the manufacture of mechanical parts and engineering structures.
3. Home Decoration: Due to its aesthetically pleasing appearance and rust-resistant and durable properties, stainless steel square tubing is widely used in home decoration, such as stainless steel security grilles, doors and windows, screens, and stair railings.
4. Public Facilities: Stainless steel square tubing is also increasingly used in public facilities, such as stainless steel fences, railings, streetlights, and decorative landscaping.
5. Automotive Mechanical Structures: Due to the durability, rust and corrosion resistance, and strong metallic texture of stainless steel square tubing, the demand for tubing used in automotive mechanical structures has increased rapidly in recent years. 6. Security windows and doors: Many security windows and doors in high-rise residential buildings are also made of stainless steel square tubing because of its long service life and high strength.
