Steel Selection:
Choose a high-quality grade structural steel (e.g. Q355B, S355GP, GR50) based on the mechanical properties.
Heating:
Heat billets/slabs to ~1,200°C for malleability.
Hot Rolling:
Shape steel into U-profile with rolling mills.
Cooling:
Cool in individual moulds or trays in tap water, shaking until they are the desired consistencu.
Straightening & Cutting:
Only length and width accuracy is checked and cut to standard or customer length.
Quality Inspection:
Perform dimensional, mechanical and visual examinations.
Surface Treatment (Optional):
Apply paint, zinc plating, or rust protection, as required.
Packaging & Shipping:
Bundle, protect, and load for transport.
Bridge Engineering: In the form of deep foundations, they increase load bearing capacity and shield the bridge structure from scour.
