1. Customization of dimensions and lengths
The length and cross-sectional specifications of W-shaped steel can be customized according to drawings and engineering requirements. Standard W series specifications from W6 to W21 are available in stock.
2. Multiple material options
Different grades of steel such as ASTM A36, ASTM A572 Grade 50, and ASTM A992 are supplied, suitable for various strength requirements and on-site construction needs.
3. Processing and supporting services
Cutting, drilling, welding, component processing, and punching can be performed. This reduces the amount of on-site processing at the construction site and helps accelerate the construction pace of the project.
4. Surface treatment options
Hot-rolled black skin, painting, and hot-dip galvanizing treatments are supported. This enhances the rust resistance of the steel and extends its service life.
5. Customized labels and packaging
Labels and product numbers can be customized. Packaging can be tied and bundled according to export standards and project requirements.
6. Quality inspection and certificates
Size verification, mechanical tests, chemical composition tests, and steel manufacturer's material certificate MTC are provided. Third-party inspections by SGS and BV can also be arranged
7. Project-specific supply solutions
or global steel structures, bridges, factories, warehouses, energy projects, and infrastructure projects, customized supply solutions for W-shaped steel are provided.
Ordinary Surface
Hot Galvanized Surface
Black Oil Surface
1.Steel Structure Buildings: Utilized as primary beams, columns, and structural members in industrial buildings, warehouses, and commercial construction projects.
2.Bridges & Infrastructure: Used in bridge construction, highways, railway stations, among other heavy-load infrastructure.
3.Industrial Plants & Factories: Commonly employed in factory frames, equipment supports, platforms, and heavy-duty structures.
4.High-Rise & Commercial Buildings: In high rises, office buildings, mall centers, and massive public buildings that necessitate robust and stable.

Packaging
1.Basic protection: The outer layer of the entire bundle of steel is covered with waterproof tarpaulin, and 2 to 3 bags of desiccant are placed inside. The bundle is then heat-sealed for sealing, effectively preventing moisture and rust.
2.Binding reinforcement: 12–16mm steel strips are used for binding, suitable for operations with American-Hong Kong lifting equipment. The weight of each bundle is limited to 2–3 tons, ensuring safer loading and unloading.
3.Compliance labels: English and Spanish bilingual labels are posted, indicating the material, specifications, HS code, batch number and test report number. The complete set of information makes it convenient for inspection and certification.
Delivery and Transportation
1.Road transportation: For short-distance delivery or goods that can be directly transported to the construction site, anti-slip fixing devices are added to prevent the goods from shifting during transportation.
2.Railway transportation: Suitable for long-distance and large-scale cargo transfer. The cost of bulk freight is better than the road plan.
3.Maritime transportation: Long-type steel can be transported by general containers, open-top containers or bulk cargo ships, flexibly matching export requirements.
4.Inland river transportation: Ultra-large-sized H-shaped steel can be transported by bulk shipment on inland waterways, with large transportation capacity and more economical freight.
5.Special transportation: For H-shaped steel that is too long, wide or heavy to be transported by regular vehicles, multi-axle low flatbed trailers are used for specialized transportation.
Exclusive Shipping Solution for North America
For ASTM H-shaped steel exported to the Americas, the steel is uniformly reinforced with steel strips, the steel ends are equipped with protection, and anti-rust processes are provided to withstand ocean transportation conditions and prevent damage and rust of the steel.
