For any warehouse, big entrance and exit spaces are essential. On the other hand securing such premises might be challenging. For such reasons it's quite common to find many warehouses are fitted with roller shutter doors. The bigger the roller shutter door is, the heavier it becomes hence for such warehouses these doors have to be automatic, gear operated or both. An automatic roller shutter door means it has been fitted with a roller shutter door motor which is remote controlled hence depends on electricity. A gear operated roller shutter door means it has been fitted with a gear pulley system which is operated by pulling on a chain to move the gears which consequently lift the door. Mostly an automatic roller shutter door will still have the gear pulley system in place as sometimes in a case where there is no electricity the motor will be rendered useless and hence the gear pulley system plays a huge role.Prices may vary since many factors are considered when doing the costing.
