Visually from the outside, it may seem that residential garage doors differ from industrial ones only in size. But is this really the only difference? Let’s dive deep into this question and try to find an answer together.
To answer this frequently asked question from customers, we will take a closer look at the design characteristics of an industrial door system that distinguish it from a series of doors for private use.
You will also learn about the fundamental differences in installation here https://fixgaragedoors.ca/services/garage-doors-repair/, price range, resource exploitation, etc.
Usually, garage doors for domestic use do not exceed 3 meters in height. Depending on the manufacturer, the maximum dimensions of the canvas are 6000×3250 mm.
The industrial series can have dimensions up to 7000×6000 m, but depending on the parameters of the customer’s opening, they can be increased to 12.5 in width and 15 meters in height.
Design Features of Industrial Doors
In general, the structures of household and industrial gates have the same structure:
- A frame of guides and beams;
- Springs for balancing and internal filling with a sandwich panel.
Typically, all parts of both series are made of stainless or galvanized steel. But the industrial series of doors has fundamentally significant differences that are visible only from the inside:
- For the manufacture of guides and corner posts, metal with a thickness of at least 2 mm is used, while for household ones, it is most often 1.5 mm;
- Reinforced side, bottom brackets, and long rollers are used;
- Instead of a hollow shaft, a solid one with a key is installed;
- To balance the web in household structures, two torsion or extension springs are used. In industrial ones, there is only a torsion mechanism, the springs of which have a larger diameter with a bar thickness of 0.9-1.1 cm. For especially large structures, more than two torsion bars are used.
Perhaps the main difference between models of gates for various purposes is the intensity of operation. Household garage doors are opened on average 2-4 times a day. Industrial ones are installed at facilities where it is necessary to work with increased intensity — opening every 20-40 minutes. Therefore, in the first case, springs with a resource of up to 25 thousand opening-closing cycles are used, in the second — an increased margin of up to 100,000.
In addition, industrial sectional doors are rather bulky, heavy construction, much larger, and heavier than domestic ones. The weight of the canvas can reach 350-600 kilograms. Therefore, to avoid the breakage of cables or the breakage of springs, they are necessarily equipped with additional protection systems.
Summing up, let’s say that although both types of gates have a common goal — to close the opening, they are structurally different. Therefore, you should not save money by purchasing standard sectional doors for commercial facilities: warehouses, workshops, stations, etc.
Using a household series in conditions that are not intended for it only increases the likelihood of a quick failure of the structure.
