1. Raw Material Selection

High-quality structural steel billets or slabs are carefully selected in accordance with specified mechanical and chemical requirements to ensure strength, durability, and performance consistency.

2. Heating

The steel billets/slabs are heated in a reheating furnace to approximately 1,100–1,200°C, achieving optimal plasticity for subsequent rolling operations.

3. Hot Rolling

Through precision rolling mills, the heated steel is continuously hot-rolled and formed into the required Z-profile geometry, ensuring accurate section dimensions and interlock integrity.

4. Controlled Cooling

After rolling, the steel profiles undergo controlled air cooling or water spray cooling to achieve the desired microstructure and mechanical properties.

5. Straightening and Cutting

The cooled sheet piles are straightened to eliminate residual stress and deformation, then cut to standard or customized lengths with strict dimensional tolerances.

6. Quality Inspection

Comprehensive inspections are conducted, including:

Dimensional accuracy checks

Mechanical property testing

Visual surface inspection
to ensure full compliance with applicable standards and project requirements.

7. Surface Treatment (Optional)

If required, surface treatments such as painting, galvanizing, or anti-corrosion coating are applied to enhance corrosion resistance and extend service life.

8. Packaging and Shipping

Finished products are securely bundled, protected, and labeled to prevent damage during handling and transportation, then prepared for domestic or international shipment.
