ASTM A328 Gr 55 JIS A5528 Z Type Steel Sheet Pile Production Process

Steel Selection:

Select quality structural steel, which meets the mechanical performance requirements.

Heating:

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

Hot Rolling:

Shape steel into Z-profile with rolling mills.

Cooling:

Cool either by natural convection or water spray to the desired moisture content of the target.

Straightening & Cutting:

Maintain accurate tolerances when cutting standard or custom lengths of material.

Quality Inspection:

Perform dimensional, mechanical, and visual inspections.

Surface Treatment (Optional):

If required, apply paint, galvanize or protect from rust.

Packaging & Shipping:

Pack, protect, and pick up for shipping.

ASTM A328 Gr 55 JIS A5528 Z Type Steel Sheet Pile Main Application

1.Port and Coastal Structures
Z-type steel sheet piles are applicable in ports, docks, shipyards and coastal defense works to resist water pressure and impact of vessels to maintain stability of waterside facilities.

2.River Works & Flood Control
They augment riverbanks, facilitate dredging, buttress embankments, and make flood-control walls, assisting in the reduction of erosion and seepage in hydraulic engineering.

3.Foundation Pits & Deep Excavation
In buildings, metro and basement excavations, Z-piles can be used as temporary or permanent retaining or load-bearing elements for maintaining excavation safety and neighboring structure protection.

4.Industrial & Water Conservancy Projects
Z-type piles provide robust support and waterproof services to laborious industrial, water conservancy and agricultural tasks, and are fully suitable for hydropower houses, pumping stations, pipeline ditches and bridge piers.

Packaging & Shipping

Steel Sheet Piling Packaging

Bundling: Sheet piles are bundled into stable packs with the application of either steel strapping or plastic strapping.

End Protection: Ends of bundles are banded with plastic and/or bundled with wood to protect during handling.

Rust prevention: the piles are protected from rust by waterproof wrapping, rust inhibiting oil or plastic sleeve during the storage and the transportation.

Steel Sheet Pile Transport-SBP

Loading: Crane or forklift lifts bundles onto trucks, flatbeds or trailers safely and efficiently.

Transit Security: Bundles are piled and fastened together.

Hoffman said East Texas Tie unloads the bundles in a planned sequence, allowing convenient access and a seamless flow into the construction work at the job site.
