1. Equipment Definition
The single-layer small trapezoidal color-coated steel roll forming machine** is a cold roll forming device specifically designed to produce **narrow-width, small trapezoidal-section color-coated steel sheets**. It processes lightweight materials such as **color-coated steel sheets** and **galvanized steel plates** with thicknesses ranging from **0.3-0.8mm**, widely used in temporary structures, agricultural facilities, and simple roofing.
2. Core Structure and Workflow
Key Components
Uncoiling System: Automatically feeds and straightens metal coils.
Guiding Unit: Ensures precise alignment during material entry.
Roll Forming Unit: 8-12 precision rollers progressively shape flat sheets into trapezoidal profiles.
Hydraulic Cutting Syste: Cuts formed sheets to preset lengths (typically 1-6 meters).
Control System: PLC control panel for adjusting speed and cutting parameters.

5. Key Advantages
1. Cost-Effective & Efficient
Simplified single-layer design, priced at 1/3 of large industrial machines.
2. Flexible Configuration
Quick mold change (<30 minutes) for different trapezoidal heights (15-30mm).
3. Energy & Material Savings
Variable-speed control reduces idle energy consumption; material utilization >98%.
4. User-Friendly Operation
- 1-hour training suffices for operators; 15% lower failure rate than industry average.
6. Selection Guide
1. Material Compatibility:
Choose chrome-plated rollers for galvanized steel; **rubber-coated rollers prevent scratches on color-coated sheets.
2. Production Volume:
Low-volume (<2000m/day): Electric cutter.
Medium-volume (2000-5000m/day): Hydraulic cutting system.
3. Space Constraints:
Compact models (<6m length) suit workshops <50m².
