Place of application
The practice of recent decades clearly demonstrates that the density of development in the city line increases. Each plot, any piece of land has to be used with maximum rationality. In countries with a developed market economy, such conditions have been formed for a long time. In the city quarters of the old buildings, it is almost impossible to build a new building for a outlet. However, you can convert existing rooms for these purposes. Living space on the first floors and half -bases began to be used for stores. The result of this approach is seen and used by all people living and arriving in the city.
Huge glass windows allow you to see the entire range of goods without going to the store. Of course, this is convenient for buyers, but the glass is fragile material. And when the working day ends and the darkness is thickening such a window must be protected. For this purpose, roller shutters are used. When they are lowered, this serves as a signal that the store is closed. And the second function of these shutters, which is considered the main one, they reliably protect the showcase from damage. And the store premises, as written in police protocols, from unauthorized penetrations of unidentified persons.
One of the mandatory attributes of the city lifestyle is a personal car. And these cars need to park somewhere. Everyone knows that the best place for parking a car is a garage boxing. However, another is well known. Land plots, for the construction of these same garages, is always not enough. And the garages always “sculpt” and crowded one to another. It is increasingly developing so that traditional swing gates are not possible to use it. Emergency more. Both design requires additional areas and space, which are just not enough. And here they are replaced by roller.
Design and materials
If you describe the design of the roller worship in principle, then they consist of three elements. The first is the collar canvas. The second is a box in which the canvas is placed when it is twisted into a roll. The third element is guide profiles. For a more visual presentation of this design, one can imagine a piece of fabric several meters long, which is twisted into a roll, and then straightens again. So, approximately, the roller. Of particular interest in this design is the protective canvas. It is assembled from individual planks and in this sense resembles the design of the blinds. But only remind and nothing more.
These strips, in another way, are called lamellas, are a complex product. And this difficulty is explained by the fact that they provide a canvas double properties. On the one hand, this canvas should be durable, and on the other, flexible. The canvas folded into a roll takes up very little space. And in a detailed state is a strong surface resistant to mechanical influences. In order to achieve these qualities, lamellas are made of steel or aluminum. Aluminum roller shutters are more widely used. This happened for one simple reason – with equal strength, their weight is much lower than steel.
The weight of the canvas is important. Depending on the design of the roller shuttle, you can raise and lower manually. But you can use an electric drive for these purposes. In both cases, it is necessary to make certain efforts. A person in order to “cope” with such a gate needs to be strong, and the electric motor is powerful. Aluminum canvas allows you to save energy while its strength, reliability and convenience remains the same as that of steel.
