ASTM A328 Gr 50 JIS A5528 Z Type Steel Sheet Pile Corrosion prevention solution

Americas: HDG (according to ASTM A123, zinc thickness ≥ 85μm) + optional 3PE coating, marked "Environmentally friendly RoHS compliant".

Southeast Asia: Adopting a combined process of hot dip galvanizing (zinc layer thickness ≥ 100μm) and epoxy coal tar coating, its core advantage lies in no rusting even after 5,000 hours of salt spray testing, making it suitable for tropical marine climate environments.

ASTM A328 Gr 50 JIS A5528 Z Type Steel Sheet Pile Locking and waterproof performance

Design: Z-shape interlock, permeability ≤1×10⁻⁷cm/s
America: Meets the requirements of ASTM D5887, the standard test method for penetration of water through foundation and retaining walls.
Southeast Asia: High groundwater and flood-seepage resistance for tropical and monsoonal regions

ASTM A328 Gr 50 JIS A5528 Z Type Steel Sheet Pile Production Process

Steel Selection:

Select high-grade structural steel in accordance with specific 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 down either naturally or via water spray until the target moisture content is achieved.

Straightening & Cutting:

Preserve tolerance precision while cutting the material to either standard or custom-specified lengths.

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 50 JIS A5528 Z Type Steel Sheet Pile Main Application

1. Port and Dock Revetment Engineering

Z-shaped steel sheet piles find application in docks, shipyards, port revetments, and coastal protection structures. Their key role is to resist water pressure and ship impact forces, thereby safeguarding the structural safety and stability of these waterfront facilities.

2. River Management and Flood Control Embankments

In river-related and flood control projects, Z-shaped steel sheet piles are utilized for riverbank reinforcement, river channel dredging support, embankment reinforcement, and the construction of flood control walls. These applications effectively prevent soil erosion along riverbanks and water seepage through embankment structures.

3. Foundation Pit Support and Deep Foundation Engineering

Within the scope of construction projects—such as building construction, subway construction, basement excavation, and deep foundation pit digging—Z-shaped steel sheet piles serve as retaining walls or load-bearing support structures, ensuring the safety of excavation processes and surrounding structures.

4. Industrial and Water Conservancy Engineering

Z-shaped steel sheet piles are widely used in industrial and water conservancy scenarios, including hydropower stations, pumping stations, pipeline trench construction, bridge pier foundation reinforcement, and projects requiring moisture-proofing and waterproofing treatments.

Packaging & Shipping

Steel Sheet Pile Packaging Details

Bundling & Securing: Steel sheet piles are neatly grouped into bundles, which are then fastened using either steel straps or plastic straps to ensure tight, stable bundling.

End Protection Measures: The end piles of each bundle are fitted with plastic caps or padded with wooden blocks—this prevents collision damage or wear to the pile ends during handling.

Anti-Rust Protection: To shield the sheet piles from rust, protective measures such as waterproof wrapping, rust-inhibiting oil coating, or plastic sheathing can be applied, depending on storage and transit needs.

Steel Sheet Pile Transportation

Loading Operations: Bundled sheet piles are loaded onto transport vehicles (trucks, flatbeds) or shipping containers using cranes or forklifts, ensuring efficient and safe lifting.

Transit Stability Control: During loading, the bundles must be stacked stably and further secured firmly. This prevents shifting, tilting, or collision between bundles during transportation.

On-Site Unloading: Upon arrival at the construction site, the sheet pile bundles are unloaded in an organized, sequential manner—this facilitates easy access and streamlined use in subsequent construction processes.
