Compared with some other structural materials, square tubes have the advantage of light weight, which is easy to transport and install. Easy to process: It has good processing performance, convenient for cutting, welding and other operations, and can meet various complex design requirements.
Black special-shaped tubes are usually made of high-strength steel, which has the characteristics of corrosion resistance, pressure resistance, and tensile resistance, ensuring the stability and reliability of the product.
ERW (Electric Resistance Welded) pipe is formed by bending steel strips into a circular shape and welding the seam via electric resistance heating. It features precise dimensions, smooth inner/outer surfaces, and consistent wall thickness, suitable for low-to-medium pressure applications like water supply, construction, and general industrial pipelines. Cost-effective and widely produced, it balances performance with affordability for non-critical uses.
Seamless steel pipe is a type of pipe without longitudinal weld seams, formed by hot-rolling or cold-drawing seamless steel billets. It features uniform wall thickness, high structural strength, and excellent pressure resistance, widely used in petroleum, natural gas, chemical engineering, and mechanical manufacturing for transporting fluids or as structural components due to its reliable performance and durability.
