As a leading manufacturer of stainless steel tubing, we deliver unmatched quality through vertically controlled production. Our seamless tubes combine advanced metallurgy with precision engineering to meet critical specifications across industries—from petrochemical plants to medical equipment.

Core Specifications That Build Trust

✅ Premium 300 Series Grades:

• Architectural Champions: 304/L, 316/L (Coastal corrosion resistance)

• High-Temp Heroes: 310S (1150°C), 321 (Ti-stabilized for welding)

• Strength Specialists: 301/L (High tensile for seismic structures)

• Cost-Efficient Options: 430, 409, 410S (Indoor/structural components)

✅ Critical Dimensions:

• Seamless Tubes: Ø6mm – Ø630mm

• Wall Thickness: 0.5mm – 40mm (Cold-rolled for precision / Hot-rolled for heavy walls)

✅ Key Standards:
GB compliant (Equivalent to ASTM A213, EN 10216-5, JIS G3459)
