Rolling Grilles provide security with unimpeded visibility and airflow. They are available in Brick Pattern or Double Link Pattern. Constructed using 10mm dia. aluminium tube running full width, connected with round edged aluminium links separated by 12mm dia aluminium spacers giving a rigid yet flexible and secure curtain. Robust extruded aluminium bottom rail can be fitted with lockable shoot bolts or key operated two-way, two point lock. Exclusive Austral-Monsoon channel include PVC buffer to eliminate metal to metal contact and reduce noise. When spanning large openings steel rods can be used to reinforce the grille. Fixed or removable corner and centre mullions can be provided for open plan or extra wide openings. For high security applications grilles can be manufactured with plated steel components. Operation is by hand, chain or electric.
