Dual-Profile Production Flexibility: Engineered to manufacture two distinct metal roofing profiles (e.g., trapezoidal and corrugated) on a single frame, maximizing workshop space utilization while expanding product offerings without additional capital investment.
Independent Layer Drive Systems: Features completely separate motors and hydraulic stations for the upper and lower layers, allowing operators to switch between profiles instantly via the PLC interface without any mechanical reconfiguration or downtime.
Precision Hydraulic Cutting: Equipped with a universal post-cut system utilizing Cr12 mould steel blades (HRC 58-62) that accurately cuts both profiles to exact lengths with a strict ±1-2mm tolerance and clean, burr-free edges.
High-Rigidity Machine Base: Constructed on a reinforced industrial-grade steel frame that effectively absorbs forming stresses from both layers, ensuring consistent dimensional accuracy and preventing vibration during high-speed operation.
Wear-Resistant Forming Technology: Utilizes premium 45# forged steel rollers with a 0.05mm hard chrome plated surface, providing exceptional resistance to wear and guaranteeing a flawless surface finish on both roofing profiles.
The Double Layer Roll Forming Machine is an engineered solution for metal roofing manufacturers seeking to maximize production versatility within a limited footprint. This innovative equipment integrates two complete, independent roll forming systems vertically on a shared reinforced frame. The upper layer is typically configured for trapezoidal roofing panels, while the lower layer produces corrugated or alternative profiles.
