This Metal Automatic Manual Sheet Coil Hydraulic Decoiler Machine is a core auxiliary device for metal roofing equipment, specialized in uncoiling GI (galvanized steel) and PPGI (pre-painted galvanized steel) coils—raw materials for manufacturing barrel-type roofing sheets. It integrates both automatic and manual operation modes, adapting to different production scenarios: automatic mode for continuous high-volume output, and manual mode for small-batch testing or material adjustment.

Equipped with an inverter and PLC system, the machine achieves intelligent control: the inverter regulates motor speed to match the subsequent roll forming process (avoiding material accumulation or tension), while the PLC automatically controls production length and quantity. This not only ensures stable, continuous production but also reduces manual intervention—making it an ideal supporting device for cold roll forming lines in the metal roofing industry.

SHI TONG COLD ROLL FORMING MACHINARY CO.,Ltd, established in June 2000, is a seasoned manufacturer dedicated to the design and production of roll forming equipment. With over two decades of industry experience, the company has built a comprehensive product portfolio covering the entire metal processing chain, including:

• Roofing & Wall Panel Equipment: Trapezoidal steel roof/wall panel machines, barrel-type roofing sheet production lines.
• Structural Steel Equipment: C&Z shape purline machines, C/U/L light keel machines, highway guardrail machines.
• Integrated Production Lines: Sandwich panel production lines, deck forming machines.
• Auxiliary & Specialized Equipment: Shutter slat door forming machines, cutting machines, downpipe machines, gutter machines, and this hydraulic decoiler machine.

This hydraulic decoiler machine serves as a critical pre-processing device in metal roofing production, specifically for:

• Uncoiling GI/PPGI coils (common raw materials for metal roofing) to provide flat, continuous sheet material for subsequent roll forming.
• Matching with trapezoidal roof panel machines, barrel-type roofing sheet machines, and other metal roofing equipment to form a complete automated production line.
• Scenarios ranging from small workshops (small-batch roofing sheet production) to large factories (mass supply for construction projects).

The decoiler machine is the first core step in the entire metal roofing production process, with the full workflow as follows:

1. Decoiling: The hydraulic decoiler unrolls the GI/PPGI coil stably—automatic mode adjusts speed via inverter, manual mode allows manual control for precision feeding.
2. Feeding: The uncoiled flat steel sheet is conveyed to the roll forming machine at a uniform speed, synchronized with the decoiler to avoid material slack or stretching.
3. Roll Forming: The roll forming machine shapes the flat sheet into the desired roofing profile (e.g., barrel-type, trapezoidal) via multi-station rollers.
4. Cutting: The formed roofing sheet is cut to the preset length by a cutting device (controlled by the PLC system to ensure accurate dimensions).
5. Finished Product: The cut roofing sheets are conveyed to the collection area, ready for packaging or direct use in construction.
