Main Features
Accurate trapezoidal profile forming: The multi-station roller system gradually shapes the coil into a clean trapezoid rib profile with stable dimensions.
PLC touch-screen operation: The operator can set panel length, production quantity and cutting parameters directly through the HMI panel.
Hydraulic cutting with safety guard: The cutting section is equipped with a guarded structure and profile-matched die to support clean, accurate panel cutting.
Heavy-duty welded structure: The reinforced blue base and strong frame help reduce vibration and support long-term continuous production.
Flexible customization: Roller tooling, cutting die, profile size, voltage, machine color and line layout can be customized according to customer requirements.
Expandable automation: Hydraulic decoiler, leveling device, punching unit, protective film device, automatic stacker and output table can be added to build a complete production line.
Working Process
The standard working process is: metal coil loading → decoiling → sheet feeding and guiding → continuous roll forming → encoder length measuring → hydraulic cutting → finished trapezoidal roof panel output. The automatic control system coordinates forming and cutting, helping improve production efficiency and reduce manual handling.
Finished Panel Applications
The trapezoidal roof panels produced by this machine are widely used for industrial plants, logistics warehouses, steel structure buildings, commercial workshops, agricultural sheds, garages, temporary buildings, prefabricated houses and exterior wall cladding. The trapezoid profile provides a practical combination of strength, drainage performance, fast installation and modern metal building appearance.
Production Advantages
This trapezoidal roof panel roll forming machine helps manufacturers produce roofing sheets with consistent length, stable rib shape and smooth surface quality. Compared with separate bending or manual processing, continuous roll forming improves output efficiency, reduces labor cost and supports customized production for different regional roofing profiles.
Customization and Service
TOPPO Machinery can design the complete line according to supplied roof panel drawings, samples, material thickness, coil width, effective width, production speed and factory layout. Technical guidance, installation support and after-sales service are available to help customers build a reliable roofing sheet manufacturing solution.
