1. Overview
The trapezoidal color steel tile forming machine is a specialized roll-forming equipment designed to continuously produce trapezoidal-profiled color steel sheets (also known as metal roofing sheets) from coiled steel. These sheets are widely used in construction for roofing, wall cladding, and industrial buildings due to their durability, weather resistance, and aesthetic appeal.
2. Key Functions
Material Processing: Transforms pre-painted galvanized steel coils (or other metal coils) into trapezoidal-shaped sheets with precise dimensions.
Multi-Stage Roll Forming: Utilizes a series of rollers to gradually shape the metal into the desired trapezoidal profile (e.g., 840, 850, 900, or custom designs).
Cutting System: Cuts sheets to specified lengths (manually or via PLC-controlled automatic cutting).
Optional Features:
Embossing patterns for anti-slip surfaces.
Hydraulic or pneumatic punching for screw holes.
Stacking/conveyor systems for automated output.
3. Applications
Roofing & Wall Panels: For industrial plants, warehouses, commercial buildings, and residential projects.
Cold Storage & Sandwich Panels: Base material for insulated panels.
Portable Shelters & Container Houses: Lightweight and corrosion-resistant structures.
4. Machine Structure
Uncoiler: Holds and feeds the steel coil into the machine.
Roll-Forming Stations: Multiple sets of rollers progressively bend the metal into the trapezoidal profile.
Cutting Unit:
Hydraulic Guillotine or Flying Cut-Off System for precise length cutting.
Control System:
PLC + HMI for automation, adjustable speed, length, and production monitoring.
Support Frame: Heavy-duty steel structure for stability.
Auxiliary Components:
Lubrication system for rollers.
Safety guards and emergency stop.
5. Technical Parameters
Material Thickness: 0.3-0.8 mm (typically).
Sheet Width: Adjustable (e.g., 600-1200 mm).
Profile Height: 20-100 mm (varies by trapezoidal design).
Production Speed: 5-30 m/min (depends on model).
Power Supply: 3-phase, 380V/50Hz (or customized).
6. Advantages
High Efficiency: Continuous production with minimal waste.
Customization: Adaptable to different profiles and sizes.
Low Maintenance: Robust design with wear-resistant rollers.
This machine is essential for modern metal construction, offering speed, precision, and versatility for mass production of trapezoidal color steel tiles.
