Thin Wall Thickness Big Outer Diameter High Precision Welded Steel Tube and Steel Round Pipe
Our thin-walled, high-precision welded steel tubes feature large outer diameters, ideal for demanding industrial applications. With reduced wall thickness, these tubes offer increased flexibility and reduced weight without compromising strength. Manufactured from high-quality steel alloys, our tubes undergo rigorous testing to ensure exceptional accuracy, durability, and resistance to corrosion and wear.
Perfect for use in machinery components, hydraulic systems, and other heavy-duty applications.
Available materials include: E215, E255, C35E, C45E, E355, 26MnB5, 34MnB5, 50CrVA, SAE1026, SAE5160H, PA12, MT1010, 45#, GCr15, GCr9SiMn, PA12, 100 Cr6, and more.
