A steel rolling shutter slat roll forming machine has been designed to produce horizontal roller shutter door slats out of galvanized or prepainted steel strips.

Pictures aobut how a roller shutter door works

A rolling shutter door or roller shutter door is a type of door that consists of many horizontal slats hinge together and the door opens and closes by raising up or lowering down along a rolling shutter door track or guide rails (more at rolling shutter door track roll forming machine)

Compared to a traditional door, a roller shutter door has different close or open method. A traditional door is open or method by rotating from 0-90 degress, while a roller shutter door opens and closes by raising up and lowering down, and the ending of a roller shutter is a roundel along which the shutter door will be rolled when raised up.

Rolling shutter slats hinge together.

Another difference is a roller shutter always changes its shapes when closing and openning (a roller shutter door is square or rectangular shape when lowered down to close and it becomes a barrel or drum shape when raised up to open) due to its composition structure; while a traditional door changes only position not the shape itself.

In order to save more spaces and and make door open and close more conveniently, the idea of using rolling shutter doors has been came out and thanks to the development of rollforming technologies, the real rolling shutter doors have been produced by the designing and building of a steel roller shutter door slat roll forming machine.  A roller shutter can be constructed also with steel rolling shutter door panels (more at rolling shutter door panel machine) and PU or polyurethane foam  insulated shutter slats as well (more at PU Rolling shutter slat production line).

Brief Introduction of Steel Roller Shutter Door Slat Roll Forming Machine:

Roller shutter door made of galvanized steel rolling shutter slats

A steel rolling shutter door slat roll forming machine has been designed and built because of the needs for the production of steel roller shutter doors. The slats can be made out of galvanized steel strips, prepainted steel strips and some occasions alloy aluminum strips as well. This roll forming machine is technically capable to produce roller shutter slats with any lengths available and effective widths customizable from metal with thickness 0.6-1.2mm (some customers request heavy duty rolling shutter slats up to 2mm thickness).

A steel rolling shutter slat roll forming machine consists a manual decoiler, a roll fomer, transmission system, a punching tool is optional for punching slots on some types of steel roller shutter slats, a cutting tool (both a hydraulic cutter and a fly-saw cutter is available), a PLC control cabinet, a hydraulic oil pump will be equipment for hydraulic cutting tool and runout tables.
