Heavy Structural Steel Fabrication Services
Structural steel forms the backbone of modern construction and heavy industry. Its strength, durability, and versatility make it the ideal material for skyscrapers, bridges, stadiums, and massive industrial buildings.
At Openex, we provide end-to-end fabrication of heavy structural steel components. Our state-of-the-art facility is equipped with large-scale CNC beam lines, heavy plate processing machinery, and certified welding teams to handle the most complex structural projects with precision and scale. We can fabricate and trial-assemble components weighing up to 250 tons before shipping.
Structural Steel Grades We Handle
We source and fabricate a wide variety of structural steels according to international standards, complete with full material traceability.
| Steel Grade | Common Standards | Primary Use |
|---|---|---|
| Mild Structural Steel | ASTM A36, EN S275, JIS G3101 SS400 | General building construction, platforms, machinery bases. |
| High-Strength Structural Steel | ASTM A572 Gr 50, EN S355, Q345 | Bridges, heavy equipment, high-rise buildings where higher strength-to-weight ratio is needed. |
| Weathering Steel | ASTM A588 (Corten), EN S355J2W | Bridges and architectural features where atmospheric corrosion resistance is desired. |
Our Structural Steel Capabilities
Heavy Section Processing
Automated CNC beam and angle lines for high-speed cutting, drilling, and marking of large I-beams, H-beams, and channels.
Complex Welding (AWS D1.1)
Our AWS D1.1 certified welders specialize in complex structural joints, including moment connections and full-penetration welds on heavy trusses and frames.
Large-Scale Trial Assembly
We have a vast assembly area to pre-assemble and match-mark massive structures, ensuring a perfect fit-up on the final construction site.
Industrial Coating & Painting
Large-scale abrasive blasting and application of multi-coat paint systems (epoxy, polyurethane) for long-term corrosion protection.
