Why ASTM A588 Z-Type Sheet Piles?

✔ Superior Strength-to-Weight Ratio
Z-Type profiles provide higher section modulus compared to U-Type piles, reducing steel consumption while maintaining structural performance.

✔ Weathering Steel Performance
ASTM A588 is a high-strength low-alloy weathering steel, designed to resist atmospheric corrosion—ideal for long-term outdoor exposure in ports, bridges, and waterfront structures.

✔ Compatibility with US Engineering Practices
These steel sheet piles are suitable for projects designed under US engineering codes, with reliable welding and driving performance.

Common Applications in the United States

Port and harbor quay walls

Temporary and permanent cofferdams

Flood control and riverbank protection

Bridge abutments and highway structures

Industrial and commercial foundation support

Purchasing Recommendations for US Buyers

Select the Appropriate Steel Grade

SY295 for standard retaining structures

SY390 for high load-bearing and permanent works

Confirm Corrosion Requirements
In coastal or aggressive environments, additional coatings (epoxy, bitumen) may further extend service life.

Verify Mill Test Certificates (MTC)
Ensure chemical composition and mechanical properties meet ASTM A588 and JIS A5528 requirements.

Consider Logistics and Lead Time
Bundled packaging and export-ready loading ensure efficient shipment to US ports.
