Export to the United States: W33 wide-flange steel beam W33×118 – 169, with MTC warranty certificate
The W33 series of American standard wide-flange W-shaped steel is compatible with materials such as A992, A572 Gr50, and A36. It has excellent section bearing capacity and is mainly used in long-span heavy-load conditions. It can replace welded plate girders in commercial frameworks, industrial buildings, and short-span bridges, thereby reducing processing costs. It is also suitable for high-rise core tube supports, main girders of large-span factories, and crane tracks in ports, etc. The product is supplied stably to the North American market and comes with a MTC material certificate, supporting fixed-length cutting and surface treatment.

1. Cutting and Material Cutting: Precisely cut the raw materials according to the drawing dimensions to ensure that the length tolerance meets the requirements of American standard engineering.
2. Forming and Arc Bending: Perform arc bending and straightening processing as needed to adapt to special structural conditions such as arc-shaped beams.
3. Welding Processing: Use standard welding techniques to complete assembly, welding of stiffening plates, and ensure the bearing capacity of weld seams.
4. Drilling and Hole Making: Drill holes according to the drawing positions to meet the requirements of on-site bolt assembly.
5. Coating treatment: We can apply coatings to the W Beam according to customer requirements, providing long-term outdoor corrosion protection for the steel.
6. Pre-assembly and verification: Before shipment, we will conduct trial assembly and size verification of the steel to reduce the on-site adjustment workload for customers.
