- Custom built to suit individual large doorway openings.
- Chain operated or motorised as required for specific purposes intended.
- Wicket gates and escape doors can be incorporated (restricted).
- Centre mullions allow unrestricted opening widths
The curtain will be manufactured from roll formed, galvanised steel, having a thickness of .6mm, .8mm or 1.0mm (as specified). Each alternative slat will be fitted with a specially moulded nylon end clip to prevent lateral movement. Shutters will be supplied with roller drum, brackets, guide channels and all necessary components and installed to manufacturers recommended specifications.
The Door curtain will be constructed using 1 00mm profile, galvanised, roll formed, interlocking steel slats in thickness of .6mm, .8mm or 1.0mm as specified.
Use:-Medium size openings in commercial applications and very large openings in industrial applications.
Size: Up to 7000mm high by 9000mm wide.
Thickness: 6mm, .8mm and 1.0mm.
Fully perforated curtains up to 7000 wide. Partially- perforated curtains up to 9000 wide.

Guide channels will be manufactured from rolled formed, galvanised steel channel section, formed to suit curtain depth and working clearance.
The. guide channels will be securely fixed to walls at intervals not greater than 750mm by masonry anchors and/or by welding to steelwork constructions.
Centre mullions can be provided for multiple installations where specified and are normally of a sliding type.
The roller drum will consist of a seamless, cylindrical tube encasing helical torsion springs matched to suit door size and weight and manufactured from a super grade wire revolving around a steel axle. The roller drum will be designed to give minimum deflection over the door span.
