Galvanized steel ducts and ducts
Ducts and ducts are critical parts of ventilation. They are made flexible, semi-rigid or rigid. In residential and industrial construction, rigid ducts are used, as a rule. Moreover, galvanized pipes for ventilation are used more often than others.
Their popularity is explained by the convenience in processing: they are easy to mount, galvanized steel can be used to design any form of air ducts. Galvanization prevents corrosion.
Moreover, even on sections, zinc, interacting with steel, creates a film that prevents corrosion of steel.
In the manufacture of galvanized steel ducts 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, excess material is used to complete the lock. It is more difficult and longer to produce welded structures, but they are of better quality. The price of galvanized pipes for ventilation depends, among other things, on the method of fastening that was used.
Pluses of galvanized pipes for ventilation:
- They do not rust for a long time;
- Not destroyed by the sun;
- Withstand frost and strong heating;
- Not destroyed by corrosive gases;
- Easy to install;
- Hygienic
- Suitable for all types of ventilation in galvanized steel.
Together with galvanized ventilation ducts, spare parts for fasteners are also purchased: adapters, tees, angles, elbows.
Galvanized Steel Duct Molds
Modern industry supplies galvanized ducts for ventilation of round, rectangular and square sections. The easiest to install round. They are also easier to clean later.
Pluses of galvanized air ducts for ventilation of circular section:
- Reduce resistance to an air stream;
- Reduce air leaks in ventilation, since all fasteners are tight;
- Less insulating material is required since the external section is in any case smaller than that of a square pipe;
- Due to nipple fastening installation costs are reduced;
- Weigh less;
- The price of galvanized pipes for ventilation is lower than stainless steel.
Installation of galvanized steel ducts
Galvanized ventilation ducts and ducts are mounted to the ceiling or wall. The simplest method is clamps and strips made of metal. However, this method has a significant minus - the pipes can “hang out” when air passes at high speed, vibrating air ducts are buzzing.
A more common and complex way is to build a track from the consoles. A similar method is used when laying ventilation made of galvanized steel with pipes of large diameters.
