Galvanized Rectangular Steel Tube

Galvanized Rectangular Steel Tubes are made of high-quality carbon steel strips, cold-bent, high-frequency ERW welded, and then hot-dip galvanized or pre-galvanized. They combine high strength, corrosion resistance, and dimensional stability, and are widely used in construction, steel structures, photovoltaics, greenhouses, fences, and machinery manufacturing.

International Standards: Supports production according to international standards such as ASTM, EN, BS, JIS, and GB.

Common Materials: Q195, Q235, Q355, ASTM A500, ASTM A53, S235JR, S355JR, etc., meeting the needs of different projects.

Standardized Production: Steel Coil → Slitting → Cold Forming → ERW Welding → Sizing → Hot-Dip Galvanizing → Straightening → Inspection → Packing.

Stable Manufacturing: Automated production lines combined with full-process quality control ensure stable product performance and high consistency.

Customizable Specifications: Supports customization of dimensions, wall thickness, and length.

Customizable Zinc Coating: Supports different zinc coating thicknesses.

Surface Treatment: Supports hot-dip galvanizing, pre-galvanizing, passivation, and other treatments.

OEM Service: Supports customization of drawings, logos, labels, and packaging.

Raw Material Inspection: Strict inspection of steel composition and surface quality.

Process Control: Real-time monitoring of forming, welding, and galvanizing processes.

Finished Product Inspection: Inspection of dimensions, welds, zinc coating, and mechanical properties.

Third-Party Inspection: Supports SGS, BV, and TÜV inspections, and provides EN10204 3.1 MTC.

Export Packaging: Steel strapping, waterproof PVC packaging, and plastic pipe cap protection.

Sea Freight Container Loading: Supports 20GP, 40GP, 40HQ, and LCL (Less than Container Load) shipping.
