Galvanized steel air ducts and ducts
Air ducts and ducts are the most important parts of ventilation. They are made flexible, semi-rigid or rigid. In residential and industrial construction, as a rule, rigid air ducts are used. Moreover, more often than others, galvanized pipes are used for ventilation.
Their popularity is due to their ease of processing: they are easy to install, any form of air ducts can be constructed from galvanized steel. Galvanized to prevent corrosion.
Moreover, even on cuts, zinc, interacting with steel, creates a film that prevents corrosion of steel.
In the production of galvanized steel boxes and ducts, rolling or edge welding is used. The first method is widely used when working with sheets up to 1.4 mm thick. Although the connections are not tight, there is extra material to complete the lock. Welded structures are more difficult to produce and take longer, but they are of higher quality. The price of galvanized pipes for ventilation depends, among other things, on which method of fastening was used.
Pluses of galvanized pipes for ventilation:
- Do not rust for a long time;
- Are not destroyed by the sun's rays;
- Withstand frost and intense heat;
- Not destroyed by corrosive gases;
- Easy to install;
- Hygienic;
- Suitable for all types of galvanized steel ventilation.
Together with galvanized ventilation boxes, spare parts for fasteners are purchased: adapters, tees, corners, bends.
Galvanized steel duct shapes
Modern industry supplies galvanized ventilation ducts of round, rectangular and square cross-section. Round are the easiest to install. They are also easier to clean later.
Advantages of galvanized round ventilation ducts:
- Reduces resistance to air flow;
- Reduces air leaks in ventilation, as all mounts are sealed;
- Less insulating material is required, since the outer section is in any case smaller than that of a square pipe;
- Due to the nipple mounting, installation costs are reduced;
- Weigh less;
- The price of galvanized pipes for ventilation is lower than that of stainless steel.
Installation of galvanized steel air ducts
Galvanized ventilation ducts and air ducts are mounted to the ceiling or wall. The simplest method is metal clamps and strips. However, this method has a significant drawback - the pipes can "dangle" when the air passes at high speed, the vibrating air ducts hum.
The more common and difficult way is to construct a track from consoles. A similar method is used when laying galvanized steel ventilation with large diameter pipes.
