I. Equipment Definition
The Roof Gutter Roll Forming Machine is an automated system that progressively bends metal coils through precision rollers to continuously produce roof drainage channels (gutters).
Core Process: Cold roll forming (no high-temperature cutting/welding)
Output: Metal gutters with U-shaped, K-style, or semi-circular profiles (common materials: galvanized steel, color-coated steel, aluminum alloy)
II. Core Components
| Module | Function |
|--------------------------|-----------------------------------------------------------------------------|
| 1. Decoiler | Automatically uncoils metal sheets with tension control to prevent deformation |
| 2. Guiding System | Precisely feeds coils into forming zone (laser correction optional) |
| 3. Roll Forming Unit | 12-24 sets of rollers progressively shape material (die steel, HRC58-62 hardness) |
| 4. Hydraulic Cutter | Servo-positioned cutting (±0.5mm accuracy, burr-free) |
| 5. Auto Stacker | Collects finished gutters (pneumatic/robotic options available) |
III. Key Advantages
1. High Efficiency
Line speed: 6-15 m/min (~1 standard gutter/10 seconds)
Supports 24/7 continuous operation (daily output: 1-3 km)
2. Precision Forming
Material thickness: 0.4mm-1.2mm (adapts to strength requirements)
olerance: ±0.1mm (ensures waterproof sealing)
3. Customization Flexibility
Interchangeable molds for multiple profiles (e.g., U-type 100-300mm width, K-type 50-150mm depth)
Quick mold change (<30 minutes for specification switching)
4. Energy Efficiency
Power consumption: <15 kW (40% savings vs. traditional stamping)
Material utilization: ≥99% (no waste from punching)
IV. Gutter Profile Comparison
|Profile | Application | Equipment Requirements |
|---------------|-------------------------------|----------------------------------|
| U-Type | Residential/light steel structures | Basic roller sets (12-16 stations) |
| K-Type | Villas/commercial buildings | Reinforced rollers + embossing module (18 stations) |
| Custom | Historic building restoration | 3D scanning + special roller customization |
V. South Africa Market Adaptations
Critical enhancements for local conditions:
1. Corrosion Resistance
Rollers with hard chrome plating (withstands abrasion from Aluzinc®)
Stainless steel guides (resists coastal salt corrosion)
2. Power Compatibility
Wide voltage range: 380V±15% (handles grid fluctuations)
Optional diesel generator drive
3. Maintenance Accessibility
Modular design (key components replaceable in 30 mins)
Dust-proof sealed bearings (reduces sand ingress)
VI. Applications
1. Construction firms: On-demand gutter supply for cost reduction
2. Building material plants: Government projects (e.g., South Africa's RDP housing)
3. Metal workshops: Upgrade from welding to value-added roll forming
