Industrial Doors


Alimatic  AAS Ltd's high specification Roller Shutter Doors are designed to give clear, full width and height access through external openings and low maintenance, trouble free, service. A choice of widths and heights is available, as every door is made to customer's individual requirements, and can be fixed behind the opening or, if necessary, between.


Door curtains are constructed from a number of 75mm deep steel laths, the gauge suited to the door width and wind loading. Nylon or PVC end locks and steel retainers are fixed to alternate laths. The bottom rail provides strength and is formed from steel strip 'T' section, angle or box section as necessary, for minimum lateral deflection.


The door runs in vertical guides made from heavy gauge, galvanised 'U' section steel. The roller, usually fitted behind the lintel, accommodates the door when open, and is made from steel tube, inside which is the counterbalancing tempered helical spring(s). The roller is mounted on bearings on supporting steel end plates, which also house single or double reduction gears for ease of operation.


Operation can be manual via continuous chain or push up with pull down cord/rod, or electrical via appropriate single or 3 phase motor with push button control and emergency cut-off with hand operation facility. Automatic activation can be by all types of electronic control mechanisms and safety edges can be supplied. Options include pass door, canopy and fascia, motor hood, and weather and draught seals.
