Roller shutters are truly an innovation in door design – compact, resistant to a lot of things like dust, weather and pests. They take up far less space than an open-up garage door, need no clearance space to open up, are stronger than an open-up door and cheaper to fix if damaged as compared to an open-up door. Pretty sweet, huh? But do any of us know how these doors are made, and how they work? We bet you’d be hard pressed to find someone who is informed about this matter. It is rather ironic though; most of us see them around us and even use them but have no idea about how they are made or how they work. And that is what we’re tackling today. Here’s the gist of what you need to know about our entryway solution for things a little to large.

The Making

Let’s first look into how the roller shutters are manufactured. Large sheets of either polyvinyl chloride or aluminium are first cut into smaller rectangular pieces and then bent and further cut into a long sheet that has a somewhat S-shaped cross section, with ends that can interlock into another similar piece. The pieces are then manually interlocked with each other, to create a roller shutter (of the bent sheets) of desired length, since requirements for each client may vary. That’s how just the shutter is made.

Moving onto the shutter housing, this may be made of either wood or metal (it’s worthy to note that the housing and shutter are made separately, and then assembled later on). A few pieces of metal or wood are cut into specific lengths and are fixed to each other (using screws, nails etc.) to create the housing box for the shutter, and have a metal rod running through the housing box, to which the separately assembled shutter will be affixed to.

Once the shutter is mounted inside the housing to create the main product, a spring is mounted to the housing (for non-motorised models) to allow the user to simply lift the shutter up a little to open the door. But with that being said, most roller shutters are nowadays motorised, to provide ease of opening for those who cannot lift the shutter. Therefore, a motor is mounted to the housing and this motor is controlled either by a manual winder key on the garage entrance, or with a remote control.

Additionally, rails for the shutter made from steel sheets in a similar process are also made, completing the product.

How It Works

It’s pretty simple actually. If the roller isn’t motorised, the added spring allows the user to lift the shutter slightly to open the door, and pull it down just a little to close it. Either that, or you crank a key that turns the axle rod in the housing at the garage entrance, usually placed well below head level, to bring up or close the shutter. Really pretty simple for this one. However, if you motorise the shutter, the axle rod inside the shutter housing is made to turn in response to the motor added. This motor is either controlled with a remote-control device, or a wired switch console installed on the garage entrance.
