Custom Metal Fabrication Services Precision Parts Machinery Parts Manufacturing

Our high-strength welded steel structure components are manufactured from premium Q235/Q345 carbon steel or stainless steel. Precision cutting, welding, polishing, and surface anti-corrosion treatments ensure excellent mechanical properties and durability. Welding processes comply with AWS D1.1 or GB/T 50661 standards, utilizing CO₂ gas shielded welding or submerged arc welding for full, well-fused welds that guarantee structural strength and stability.

These components are widely used in bridges, buildings, heavy machinery, offshore platforms, wind power foundations, and other industrial applications. Customization options include dimensions, connection methods, and surface treatments (hot-dip galvanizing, painting, oxidation, etc.). Our strict quality control system ensures compliance with industry standards for reliable performance in engineering projects.
