Product Description
Bending Structural Steel Fabrication / Arch Shaped Curved Girders Steel Structure is designed for structural applications requiring curved steel components, particularly in steel bridge construction where longitudinal and lateral slopes are required.
Fabrication Process for Arc Shaped Steel Beams
Curved steel structural members are categorized into H-shaped steel bending and steel pipe or truss bending:
- H-section arc shaped steel beams are fabricated by cutting the web into the required arc shape
- Steel truss arc shaped beams are produced through cold bending or hot bending of the lower chord
Our Steel Structure Fabrication Facility
Our factory features three dedicated production lines equipped with:
- Flame cutting machines
- H-Section steel assembly machines
- Gantry welding machines
- Shot-blasting machines
- Paint spray booths
We maintain specialized workshop space for fabricating heavy-duty and large structural steel components.
