Handa Structural Steel Pipes are designed for a wide range of construction and structural applications, manufactured in compliance with Chinese standards GB/T 8162-2008 and GB/T 3091-2008. These pipes are available in multiple formats including hot-rolled seamless, cold-drawn seamless, and welded (straight or spiral), offering versatility for industrial, civil engineering, and low-pressure fluid transport use.
Hot-Rolled Seamless Steel Pipes are manufactured using extrusion or expansion methods, offering robust structural integrity for heavy-duty applications. With outer diameters from 32mm to 630mm and wall thicknesses between 2.5mm and 75mm, they are suitable for load-bearing construction.
Cold-Drawn Seamless Steel Pipes provide excellent dimensional precision and surface finish, making them ideal for precision structural components. Sizes range from 5mm to 200mm OD with wall thicknesses from 2.5mm to 12mm.
Straight Welded Steel Pipes, formed by crimping and welding steel plates or strips, adhere to GB/T 3091-2008 standards. With diameters from 5mm to 508mm and wall thicknesses of 0.5mm to 12.7mm, they serve in lightweight structural and low-pressure systems.
Spiral Welded Steel Pipes are manufactured by spirally forming steel strips and welding the seam. These pipes offer enhanced strength and adaptability in various structural frameworks, especially where longer lengths and larger diameters are required.
All product types are suitable for low-pressure fluid transport, general steel structures, scaffolding, civil infrastructure, and machinery frameworks.
