Today, lifting garage gates can be several types. First of all, the method of opening is taken into account. There are three main options. Rolled and lifting-hooting analogues are less common than sectional garage gates. The latter are incredible popular.
They call them so because of the special design of the canvas. It includes horizontal steel panels resembling sections. Sectional garage gates can actually be single -layer or two -layer.
In the first case, they are a single metal sheet with a thickness of 0.5 to 1 millimeter. He also has special stiffness ribs. In the second case, the design resembles a sandwich panel with a heater inside. Single -layer canvases are not designed to hold heat, therefore, as a rule, they are installed in cold garages that do not have heating. However, they have their advantages, which are relatively lightweight and low cost. Sometimes it is very important.
The average price category includes products collected from the panels of different -sized thicknesses. In places of joints, the panel thickness is more twice as. Accordingly, in the middle it is smaller (420/200 mm). We can say that the thermal conductivity of such models is at an average level. For areas with a temperate climate, they are quite suitable. As for the thermal conductivity of the homogeneous gate, it can be compared with brick masonry with a half -brick thickness.
Reliable tightness of the sectional gate is achieved using a rubber seal. It stretches around the entire perimeter. In the gate designed to retain heat, sealing gaskets are also installed in sections of sections. From above and below, the panel has a steel stripes that help strengthen the structure as a whole. Thus, sectional garage gates gain high protection against hacking.
