A rain gutter is an important component of any building’s exterior that collects and diverts rainwater runoff from the roof. Choosing the right gutter system and installation method is crucial for effective water management. Roll forming machines are an efficient automated way to manufacture rain gutters on-site or in factories using roll forming technology.
This guide provides a comprehensive overview of rain gutter roll formers from China – their working, types, main parts, specifications, suppliers, and more. We have structured the information in easy-to-compare tables and outlined the main factors to consider when deciding on a Chinese roll former for rain gutters.
Overview of China Rain Gutter Roll Forming Machines
Rain gutter roll forming machines are a popular metal forming technology originating from China. They can rapidly convert flat metal sheets into curved u-channel rain gutters through a series of consecutive forming stations.

How Rain Gutter Roll Forming Machines Work
Rain gutter roll forming machines work on the principle of continuous bending and folding of sheet metal through consecutive rollers to gradually shape the material into a u-channel rain gutter profile.
The key processes involved are:
- Feeding – Coiled steel sheet loaded at back of the machine is unrolled and fed into the roll former line.
- Forming – Sheet passes through many roller stations which progressively bend it into a u-channel.
- काट रहा है – Formed u-channel is cut into required gutter lengths by built-in hydraulic shearing blade.
- Output – U-channel rain gutter pieces of finished length exit the roll former continuously.

सामान्य प्रश्न
Q1. What materials can the rain gutter roll former process?
Most China roll formers for gutters can process galvanized steel and zinc steel coils ranging from 0.3mm to 0.8mm thickness. Some heavy duty models can also process stainless steel and aluminum sheets up to 1mm thick.
Q2. What is the typical production capacity?
A standard electric China rain gutter roll former with 3kw motor can produce around 15-25 meters of gutter per minute. For an 8 hour shift, it equates to 720-1200 meters or 800-1400 PCS of 3m gutter pieces a day.
Q3. Can these machines make custom gutters?
Many Chinese manufacturers can customize the roll forming lines to produce specialized gutter profiles, sizes, and lengths as per client requirements. The roller dies and machine would need to be tailored accordingly.
Q4. How to reduce defects in finished gutters?
