In the building drainage system, the semi-circular gutter is widely used on the roof eaves of various buildings due to its superior hydraulic performance and classic appearance. However, its curved cross-section is precisely the biggest pain point of traditional processing methods.
The Half Round Rain gutter metal profile making roll forming machine is precisely designed to overcome this challenge. It is a highly integrated automated cold bending production line that can roll and press rolled color-coated steel plates, galvanized steel plates, or aluminum plates into standard semi-circular or circular sections continuously in one operation through a series of precisely arranged forming rolls, and simultaneously complete the cutting to length. It brings gutter production out of the discrete mode of “cutting-bending-splicing-welding” and into a new era of one-machine forming.

Core processes and composition:
1.Uncoiler: Supports metal coils and discharges them passively or actively.
2.Guidance and leveling: Ensure the strip material enters the rollers straightly and accurately.
3.Cold bending forming machine: The core of the equipment, which gradually bends flat plates into semicircles using multiple sets of rollers. The precision determines the quality of the finished product.
4.Cutting device: Online fixed-length flying saw or hydraulic shear, enabling non-stop cutting.
5.Control system: It typically employs PLC control and is equipped with a touch screen, allowing for the setting of parameters such as length and speed.
6.Material receiving table: Collect the finished products after cutting.

Equipment Features:
1.flexibility
By replacing the roller set, the same production line can produce semi-circular gutters with different radii. The control system also supports rapid adjustment of length.
2.High degree of automation
After setting the parameters, it can run automatically, usually requiring only 1-2 people to operate the loading and unloading. It can integrate processes such as punching and folding.
3.High material utilization rate
Cutting to length results in almost no scrap material, making it especially suitable for mass production.

Application Scenarios:
- Industrial and large public buildings:
such as large factories, warehouses, stadiums, and exhibition halls. These buildings have large roof areas and high requirements for drainage efficiency, making semi-circular gutters an ideal choice. - Residential buildings:
In villas and multi-story residences, semi-circular gutters serve as important functional and decorative elements. - Renovation and transformation of old buildings:
When replacing outdated drainage systems, standardized metal gutters can be quickly installed, enhancing both performance and aesthetics.
