JIS Sy390 U Type Steel Sheet Pile Production Process

Steel Selection:

Choose high-quality structural steel based on the mechanical properties and performance requirements of your project.

Heating:

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

Hot Rolling:

Roll steel into U channels with rolling mills.

Cooling:

Air or fire cool cool in water for the desired effect.

Straightening & Cutting:

Measure the exact dimensions and cut to standard size or length or to special size or length.

Quality Inspection:

Conduct dimensional, mechanical, and visual tests.

Surface Treatment (Optional):

Apply paints, galvanizing or rust-preventive oils as needful.

Packaging & Shipping:

Bundle, protect, and load for transport.

JIS Sy390 U Type Steel Sheet Pile Main Application

Harbor and Dock Construction: Steel sheet piles form a rigid wall to retain shore protection.

Bridge Engineering: They enhance the load-carrying capacity and act as scour protection for bridge piers when driven as batter piles.

Underground Parking / Deep Foundation Support: Safe, effective lateral support for your excavation.

Water Conservancy Projects: Offer high efficient water barriers for river training, dam strengthening and cofferdam construction.

Port and Wharf construction

Bridge Engineering

Deep foundation pit support for underground parking lots

Water conservancy projects
