DUWELL designs and manufactures rolling shutter slat roll forming machine systems for producing flat, curved, and custom metal shutter profiles. The line continuously forms cold-rolled steel, pre-painted steel, galvanized steel, stainless steel, or aluminum coils into accurately shaped slats for commercial, industrial, and residential roller shutter doors.
According to the approved profile and line configuration, the machine typically processes 0.5–1.5 mm metal coil at 8–25 m/min. PLC control coordinates feeding, roll forming, length setting, and cutting. Hydraulic or servo-following cutting and optional micro-perforation or window-hole punching can be configured for the finished shutter design.
For manufacturers planning a complete roller shutter door machine system, DUWELL can also supply guide rail, bottom slat, shutter box, door frame, punching, and auxiliary equipment around the required door structure.
DUWELL specializes in the design and manufacturing of roller shutter roll forming machine systems for various shutter door applications. Our machines support a wide range of slat profiles, including flat slats, curved slats, and customized shutter profiles. Our shutter slat machine is suitable for processing different materials such as pre-painted steel, galvanized steel, stainless steel, and aluminum.
In addition to rolling shutter slat roll forming machine, DUWELL also provides a full range of roller shutter door machine components and production equipment, including guide rail roll forming machines, micro-perforation punching machines, rolling shutter bottom machine solutions, and related auxiliary equipment. These systems can be seamlessly integrated with the rolling shutter slat roll forming machine to build a complete and efficient roller shutter production line.

Optional punching: A press or hydraulic punching unit creates micro-perforations or square window holes when required.
Roll forming: The strip passes through progressive roller stations to create the shutter slat profile.
Straightness adjustment: The adjusting device corrects the final slat straightness.
Cutting: The profile is cut to the programmed length by the selected hydraulic or servo-following system.
Run-out: Finished slats are received on the run-out table for collection and stacking.
Duwell shutter slat machine is widely used in commercial, industrial, and residential shutter door manufacturing.
The DUWELL automatic roller shutter door roll forming machine line is engineered around the customer's profile dimensions and finished shutter requirements. Typical products include:
| Slat or profile type | Available features | Typical application |
| Flat shutter slats | Smooth or formed surface, customized width and lock geometry | Commercial shops, counters, and interior security shutters |
| Curved shutter slats | Profile curvature and interlocking edges made to drawing | Residential, commercial, and industrial roller shutters |
| Micro-perforated slats | Press or hydraulic punching for ventilation and visibility | Retail storefronts, shopping areas, and ventilated closures |
| Slats with square window holes | Customized window position and repeat pattern | Security shutters requiring partial visibility |
| Custom shutter profiles | Tooling designed from a profile drawing or physical sample | Project-specific shutter doors and replacement profiles |
Uncoiler: Loading the steel or aluminum coil
Profiling Roll Forming Machine: For precise profile forming and stable operation as a high-performance rolling shutter forming machine.
Adjusting device: For final slats straight adjusting.
Hydraulic cutting: For precise cuts.
Out Table: Stacking the finished slats.
Each rolling shutter slat roll forming machine is engineered for smooth feeding, accurate forming, and stable cutting performance.
This equipment can also be configured as a rolling shutter door machine or shutter door roll forming machine according to different shutter slat specifications and production requirements.
