Roller shutters are made to protect your property. They add an extra layer of protection to entry points such as windows and floor doors, making sure that the vulnerable parts are safe. They come in different designs, but you can also customise them to look and fit the style you are going for. You can also have them fitted with a pelmet, for example, to hide the mechanisms that may not be pleasing to the eye.
Most industrial roller shutters run on tubular motors. They do not always look the same, but there are components that cut across the board. They include the following parts:
Flag post and check plate
Also called end plates, check plates support the roller. They are typically secured to the structure of the building using fixings. The design of the check plates is such that they can bear the weight of the curtain without giving in. Where the end plates join the structure of the building, they look like a flag post. It is usually welded either directly or at an angle to give extra support to the shutter.
Tubular motor and rollers
The cheek plates often support a shutter curtain with a roller stretching along the full width. These rollers contain a motor on one side of a tube made of steel and a shank on the other. The tubular motor protrudes from the barrel and works as an analogue override for the shutters that need this feature. Inside the motor is a wire feed and switches that control the distance the curtain travels. The motor also has brakes that keep it still in upper position.
Safety brake and bearing
The brake uses centrifugal force to do its work. It sets in motion to stop the shutter from closing in the event that the motor fails. It may also set to work if the motor brake works but the shutter lowers at an uncontrollable speed. The brake stops the shutters completely. There are units that have a switch that separates the motor and the power supply. Once this brake activates, most units will need for it to be replaced or reset. Units without this safety brake will have a bearing attached at the end plates that supports the barrel.
Guides, curtain, and bottom rail
Most roller shutters have the curtains along U-shaped guides. In this case, curtain refers to that material that covers the windows. In some cases, it is made of aluminium lath and steel in others. When there are grilles, they are secured by horizontal rods. The final part gives rigidity. This bottom rail is either L- or T-shaped.
Sometimes called the hood, this fitting is often added upon request. It is usually supplied for covering the end plates. It serves to protect the barrel and curtains from dust and rainfall.
When getting roller shutters, work with a company that recognises and adheres to industry standards. For example, the barrels will need finishing for the sake of longevity. Each material, whether it is steel or aluminium, will need different finishes. Different from the choice of finish is also the expertise. A proper coat may be applied badly beating its function altogether.
