Description
Round Pipe (MS & Galvanized)
Round steel pipes are widely used structural and industrial materials known for their strength, durability, and versatility. They are available in both MS (Mild Steel) and Galvanized (GI) finishes, making them suitable for indoor structural use as well as outdoor applications requiring corrosion resistance.
Round pipes are manufactured through the ERW (Electric Resistance Welding) or seamless process, where steel strips or billets are formed and welded into precise circular shapes. The galvanized type is coated with a protective zinc layer to enhance durability and prevent rust, ensuring long service life in harsh environments.
Technical Specifications
Round pipes are available in a wide range of outer diameters, wall thicknesses, and lengths to meet different structural and industrial requirements. Common material grades include Q195, Q235, Q345 for MS pipes, and SGCC or equivalent for galvanized pipes. They are produced according to international standards such as ASTM A53, ASTM A500, EN 10219, and GB/T 3091, ensuring consistent quality and performance.
Applications
Round pipes are widely used in construction frameworks, scaffolding, fencing, water and gas pipelines, mechanical structures, and general engineering applications due to their strength and easy fabrication.
