Application description

Widely used in retaining walls, cofferdams, riverbank protection, flood barriers, bridge abutments, deep excavation support, marine structures (docks, piers, wharves), underground parking construction, and temporary or permanent earth retention. The interlocking design provides excellent water tightness and high bending strength, making it ideal for soil and water confinement in infrastructure and coastal projects.

Production description

Steel billet is heated to 1150–1250°C, then hot rolled through reversing roughing and finishing mills to form the required U or Z profile with integral clutches. The rolling process creates precise interlocking edges. The pile is then straightened, cut to length, cooled, and inspected for profile dimensions and clutch fit.

Shipping Packaging

For export, steel sheet piles are bundled with steel straps, fitted with edge protectors at clutch and corners, packed in steel frames or on ISPM-15 wooden pallets, and secured with blocking to prevent shifting. Labels include grade, profile, length, quantity, and heat number for safe sea freight.

FAQ

1. How to store steel sheet piles to prevent damage and corrosion?

Store on dry, level ground on timber sleepers or steel racks, keep bundles upright or stacked with proper dunnage to avoid bending. Protect interlocking clutches from dirt, stones, and impact. For long-term storage, apply rust preventive oil or store under cover. Surface rust is common and does not affect drivability or strength, but heavy pitting should be avoided.

2. What is the difference between U-type and Z-type steel sheet piles?

U-type piles have a symmetrical shape with clutches at both edges, offering good bending strength and easy interlocking, suitable for most retaining and cofferdam applications. Z-type piles have an asymmetrical, deeper profile with higher section modulus per meter, providing greater bending resistance for deeper excavations and higher lateral loads. Z-type is often more efficient in steel weight per square meter of wall.

3. Can steel sheet piles be reused after extraction?

Yes, if extracted carefully without damaging the interlocks or causing excessive bending, steel sheet piles can be reused multiple times. For temporary applications (cofferdams, excavation support), reuse is common and cost-effective. Inspect for clutch deformation, cracks, or severe corrosion before reuse. Lubricate clutches before re-driving.
