Production Process

Steel Selection:

Choose high-quality structural steel (e.g., Q355B, S355GP, GR50) based on mechanical properties

Heating:

Heat billets/slabs to ~1,200°C for malleability.

Hot Rolling:

Shape steel into U-profile with rolling mills.

Cooling:

Cool individually or with tap water sprays until reaching the desired consistency.

Straightening & Cutting:

Verify length and width, then cut to standard or customer-specified size.

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.

MAIN APPLICATION

Ports & Quays: Steel sheet piles interlock which makes the system very strong and stable, it can be used as retaining walls for shorelines, ports and quays.
Bridge Engineering: Acting as deep foundations, they provide increased bearing capacity and scour protection for bridges.

Subterranean Parking: Reliable lateral support to prevent dirt from collapsing in on you as you dig.

Water Projects: Ideal for application on riverbanks, dams and cofferdams in order to enhance safe and productive water management.
