Steel Sheet Pile Production process
1. Raw Material Heating
-
The Process: Steel semi-finished products, usually heavy blooms or rectangular slabs, are loaded into a walking-beam reheating furnace.
-
The Goal: The steel is uniformly heated to an optimal rolling temperature (typically between 1100°C and 1250°C) to maximize its malleability and ductility for shaping.
2. Rough Rolling & Breakdown
-
The Process: The incandescent steel slab passes through a heavy breakdown mill or roughing stand (often a reversible rolling mill) multiple times.
-
The Goal: The initial thick slab is progressively reduced in cross-section and elongated into a preliminary profile, often referred to as a "dog-bone" or beam-blank shape.
3. Universal Finishing Rolling
-
The Process: The pre-shaped steel passes through a sophisticated universal rolling mill train equipped with both horizontal and vertical rollers that apply pressure simultaneously.
-
The Goal: This is the critical stage where the final profile geometry—such as U-shape, Z-shape, or Flat/Straight web type—is formed with precise dimensional accuracy, including the highly critical, tight-tolerance interlocks on both edges.
4. Cooling and Straightening
-
The Process: The continuous hot-rolled steel profile is sectioned by hot saws and transferred to a cooling bed. Once cooled to ambient temperature, the sections are processed through a multi-roller straightening machine.
-
The Goal: Cooling stabilizes the micro-metallurgical structure, while the cold-straightening process eliminates any thermal warping, twisting, or bending to ensure perfectly straight profiles.
5. Cutting, Inspection & Finishing
-
The Process: The straightened sheet piles are cold-sawed to exact customer-specified lengths. Quality control teams perform rigorous ultrasonic and dimensional testing, particularly on the interlock tolerances and surface quality.
-
The Goal: To ensure seamless clutching performance during on-site driving. Optional post-processing—such as drilling lifting holes, applying anti-corrosion coatings, or injecting interlock sealants—is completed here prior to bundling and shipping.
Steel Sheet Pile Surface
Americas:HDG coating complies with ASTM A123 standard, with a minimum zinc coating thickness of ≥85 µm. 3PE coating is available as an optional protective system. All surface finishes are RoHS compliant, ensuring environmental safety and international export standards.
Southeast Asia: Hot-dip galvanizing (≥100 μm) combined with dual-layer epoxy coal tar coating provides over 5,000 hours salt spray resistance, suitable for tropical marine environments.
