Steel Selection
We use high-grade structural steel to guarantee the required strength and long-term durability for engineering projects.
Heating
Steel billets are heated to approximately 1,200°C to reach ideal malleability before rolling.
Hot Rolling
The heated steel is rolled into accurate U-type profiles through professional rolling mills.
Cooling
We apply natural or water cooling to stabilize and achieve the target mechanical properties.
Straightening & Cutting
Finished profiles are straightened precisely and cut to standard or customer-specified lengths.
Quality Inspection
Each product is inspected for dimensional accuracy, mechanical performance, and surface quality.
Surface Treatment (Optional)
Additional anti-corrosion treatments such as galvanizing or coating are available upon request.
Packaging & Shipping
Products are securely bundled and protected for safe delivery to job sites worldwide.
Specialized for cofferdam and retaining wall projects, also widely used in:
Cofferdam construction (river, lake, port, bridge foundation)
Retaining wall support (residential, industrial, road construction)
Foundation excavation protection and slope support
River training, coastal protection and port expansion
Temporary and permanent civil engineering structures
Certification: Provide MTC (Mill Test Certificate) and support third-party inspection (SGS, BV, Intertek).

Steel Sheet Pile Packaging & Handling/Transport Specifications
Packaging Requirements
Strapping
Steel sheet piles are bundled together, with each bundle firmly fastened using metal or plastic strapping to ensure structural integrity during handling.
End Protection
To avoid damage to bundle ends, they are either wrapped in heavy-duty plastic sheeting or capped with wooden guards—effectively shielding against impacts, scratches, or deformation.
Rust Protection
All bundles undergo anti-rust treatment: options include coating with anti-corrosive oil or full encapsulation in waterproof plastic film, which prevents oxidation and preserves material quality during storage and transit.
Handling & Transportation Protocols
Loading
Bundles are safely hoisted onto trucks or shipping containers using industrial cranes or forklifts, with strict adherence to load-bearing limits and balance guidelines to avoid tipping or damage.
Transit Stability
Bundles are stacked in a stable configuration and further secured (e.g., with additional strapping or blocking) to eliminate shifting, collision, or displacement during transportation—critical for preventing both product damage and safety hazards.
Unloading
Upon arrival at the construction site, bundles are carefully unloaded and positioned for immediate deployment, streamlining workflow and minimizing on-site handling delays.
