High Security Grille Roller Doors

The High Security Grille is a rolling grille constructed of heavy duty 12.7mm aluminium tubing which is connected by tough extruded nylon links forming a brick pattern. The High Security Grille allows airflow and ventilation as well as visibility without sacrificing strength and security.

This grille can be controlled manually or electronically. Manual operation is push up or pull down, assisted by springs, and lockable with a key. Motorised shutters can be operated with either key switch or remote control.

Single High Security Grilles can be manufactured up to a width of 3.6M or a total of 9 square metres. Larger openings can be fitted with multiple doors with a combination of standard or corner mullions. Clear anodised is the standard, whilst Dulux powder coat range is available as an optional extra.

A 12 month warranty against defective materials and workmanship applies.


The High Security Grille allows airflow and ventilation as well as visibility without sacrificing strength and security.

It is suitable for Shopping Centres, Shop Fronts, Club and Hotel Bars, Counter Tops, Kiosks, Arcades, Servereys and Doorways. 

Curtain – The curtain is constructed of heavy duty 12.7 aluminium tubing connected by tough extruded nylon links. The Links are then riveted to the aluminium tubing at brick pattern jigged spacings to provide strength as well as a pleasing appearance.

Bottom Rail – The bottom rail is manufactured from an extruded aluminium section 90mm in height and 20mm in width. The locking mechanism for the shutter is concealed in this rail and can be key-operated from both sides.

Locking – Locking is a two way key mortice lock mounted in the centre of the bottom rail that slides a steel shoot bolt out into the side guides. Standard locking position allows for double-sided locking with operation from both inside and out. Multiple doors can also be keyed alike.

Side Guides – Side Guides are 50mm deep by 30mm wide extruded aluminium suitable for face fit or through the mouth of the guide if fitted between walls.

Mullions – The standard 180 degree mullion is manufactured from an extruded aluminium section 150mm wide x 30mm; a steel shoot bolt secures the mullion into the floor. Special mullions are also available to suit a variety of degrees and applications. Special wide mullions can be manufactured 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.

Brackets – Brackets are manufactured from slotted 90mm x 40mm mild steel.

Drum – The drum is manufactured using either a 229mm or 150mm diameter spiral ducted tube with mild steel wheels and fully enclosed high grade bearings that rotate around a 33mm steel shaft. A helical coil spring designed to counterbalance the curtain weight is fitted to the shaft.
