Roller Doors in Newcastle
Roller doors are types of doors which consist of slats hinged together to form a flat surface like a curtain. When opening a roller door, raise the slats from the bottom after unlocking the fasteners and the slats will be pulled up by mechanised springs up. In the case of large doors, they are motorised to make work easier when opening and closing the doors. Here are some things to know before you install a new garage roller door.
Parts of a roller door
- Slats: these are roll-formed steel; they can be single or multi-walled. Either way, they can be hollow or insulated in design. They can also be in the form of stainless steel or aluminium.
- Roller: made of steel and supported from either end by a plate.
- Shutter box: an aluminium extrusion like a box designed to shield shutter’s inner components
- Shutter spring: a torsion spring made from spring wire, this is what pulls up the slats when closing the door to save you efforts, there is another type of spring called flat spring which is made from hardened steel strip-like, for example, C67, SAE1070, Ck67, etc.
- Guide rail: this is a steel or aluminium that is meant to retain the shutter curtain in between the opening. It could be weather-sealed to improve product life and reduce vibrations.
- Bottom slat: this may be steel or aluminium or even PVC that matches the rest of the shutter curtain. A safety edge can be added in the form of rubber or weather seal to reduce draught.
- Lock: lock is used to secure the slats in place. It can be bullet lock or slide lock used to manually secure the curtain slats. Slim locks can be installed within the last slat. It should have bars that lock the shutter firmly on to the guide rail.
