Premium Welded Steel Tubes: Built for Durability & Versatility
Sleek & Precision-Crafted Design
Our welded steel tubes feature a seamless, uniform appearance with precise geometric dimensions. Available in round, square, rectangular, and custom profiles, we offer diameters from 12mm to 1200mm and thicknesses 0.5mm–20mm. The smooth, burr-free surface is coated with anti-corrosion treatments (galvanized, painted, or epoxy) for a professional finish ready for immediate use.
Key Technical Features
✅ Superior Material
Manufactured from ASTM/EN-certified carbon steel, stainless steel, or alloy steel to ensure structural integrity.
✅ Advanced Welding Technology
High-frequency induction welding (HFIW) and TIG welding ensure 100% leak-proof seams with ultra-low porosity.
✅ Rigorous Quality Control
Eddy current testing, hydrostatic pressure checks, and dimensional tolerance <±0.5% compliance.
✅ Corrosion Resistance
Optional galvanization (up to 600g/m² zinc coating) or 316L stainless steel for harsh environments.
✅ Eco-Friendly Production
ISO 14001-certified facilities with recyclable materials and low-VOC coatings.
