Each individual Security Door and Roller Grille can be manufactured up to a width of 3.6m or a total of 9 square metres. For larger openings, the shutter can be fitted with any number of standard or corner mullions.
The curtain is manufactured by alternating and interlocking 80mm or 100mm x 20mm x 1.5mm extruded aluminium links with 30mm extruded aluminium slats, in 6063-T5 alloy to form a continuous hinge. Each joining slat is fitted with moulded nylon end clips to prevent lateral movement and provide a smooth and quiet operation inside the side guides. Link size, spacing and curtain format can be changed to any layout. Polycarbonate infills can also be added.
The bottom rail of the shutter is manufactured from an extruded aluminium section fitted with an extruded aluminium cover plate for added security and can also be used as a mid-rail lock at any position in the door. The bottom rail foot comes in two options: as one extrusion with the bottom rail or a separate extrusion as a add on.
The bottom rail houses a keyed centre lock within the extrusion. This operates 25mm x 3mm aluminium flat bars which, when in the locked position, secure into the side guides on both sides of the opening. The standard locking position allows for double-sided lock with operation from both inside and out. Multiple doors can be keyed alike.
The guides are manufactured from an extruded aluminium section 50mm deep x 31mm wide. Optional felt brush available.
Standard 180 degree mullions are manufactured from an extruded aluminium section 130mm deep x 31mm wide and shall be lift out types with shoot bolts to the base. Special wide mullions to suit any angle shall be fabricated with 1.6mm aluminium sheet securely fitted to our standard side guides for angle openings where doors need to be stacked.

The drum is manufactured from 200mm diameter spiral ducted tube attached to mild steel wheels with fully enclosed ball bearings which rotate around a 34mm steel shaft with next to no friction. The shaft shall be fitted with helical coil springs designed to counterbalance the curtain weight throughout its full operation.
