Each individual Mini-Grille aluminium roller shutter can be manufactured up to a width of 3.6m or a total of 9 square metres.


The curtain is manufactured by alternating and interlocking 45mm x 30mm x 1.5mm extruded aluminium links with 36mm 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.

Bottom Rail

The bottom rail of the shutter is manufactured from an extruded aluminium section 65mm x 10mm which shall encase a locking device. Optional felt brush available.


The bottom rail houses a keyed centre lock within the extrusion. This operates 15mm x 2mm 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.
