            A500 Grade B, C, and D square tubes all adopt the A500 standard issued by the American Standards Association (ASTM), and meet internationally recognized standards in terms of quality and performance. They are cold-formed welded and seamless carbon steel square tubes that can be used for welded, riveted or bolted structures of bridges and buildings, as well as general structural purposes. In terms of production specifications, the circumference of welded and seamless sizes is 64 inches (1626mm) or less, and the specified wall thickness is 0.625 inches (15.88mm) or less. Grade D requires heat treatment, and the steel density is about 7850 kg/m³ (0.284 pounds/cubic inch).
 
            SPHC has added special elements (P, Cu, C, etc.) and has good corrosion resistance and atmospheric corrosion resistance. SPHD has a thickness of 1.2 - 8mm and a width of less than 600mm, which is called narrow strip steel, and those over 600mm are wide strip steel. Its carbon content is slightly higher than that of cold-rolled steel plates. When the components are not much different, its density is the same as that of cold-rolled steel plates. SPHE is made by pressing low-carbon steel and ordinary alloy steel at high temperature.
 
            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.
