Our hot-rolled carbon steel pipes come in diverse categories, including general-use steel pipes, low and medium-pressure boiler steel pipes, high-pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, and geological steel pipes, catering to a wide range of industrial needs.
Beyond the ordinary, our cold-rolled carbon steel pipes extend to include carbon thin-walled steel pipes, alloy thin-walled steel pipes, non-rust thin-walled steel pipes, and special-shaped steel pipes. With hot-rolled seamless pipes boasting diameters over 32mm and wall thicknesses of 2.5-75mm, and cold-rolled variants achieving diameters as small as 6mm with wall thicknesses of just 0.25mm, we deliver unmatched precision and quality. Our thin-walled pipes reach a diameter of 5mm with wall thicknesses under 0.25mm, where cold rolling ensures superior dimensional accuracy over hot rolling.
