Profile Information
Square downspout pipes are used for roof rainwater drainage. Their closed square shape provides clean appearance, efficient water flow, and compatibility with various building designs and sizes.
Square downspout pipes commonly use 0.4-0.8mm galvanized steel, color-coated steel, or aluminum coils because these materials provide corrosion resistance, outdoor durability, and stable forming performance.
How Does The Roll Forming Machine Work?
Machine Details
Steel Coil Decoiler
Steel coil decoiler is used to unwind metal coils smoothly for feeding into roll forming, cutting, or punching processes.
Manual decoiler is a basic and economical option, while motorized and hydraulic decoilers are also available for higher efficiency and automation:
| Power Type | Manual | Steel Coil Width | Max 1250mm |
| Loading Capacity | 3/5/7/10 Ton | Expanding Range | 460-50mm |
Roll Forming Machine
The wall panel chain-drive roll forming machine gradually shapes flat steel coils into closed square downspout pipes through multiple forming stations.
Specialized seaming rollers lock and press the joint tightly for stable pipe structure and clean appearance.
Compared with gearbox-driven configurations, chain transmission offers lower investment cost and easier maintenance for standard production requirements.
| Speed | 20m/min | Forming Station | 18 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
