Galvanized welded air ducts are indispensable key components in building ventilation systems. With their excellent performance and wide applicability, they have become the preferred materials for ventilation projects in industrial, commercial, and civil fields. The following provides a detailed explanation from two aspects: core uses and installation specifications.
I. Core Uses of Galvanized Welded Air Ducts
1. Efficient Ventilation and Air Circulation
Galvanized welded air ducts are mainly used for the directional transportation and circulation of air inside and outside buildings. For example, in air - conditioning systems, they are used to adjust indoor temperature and humidity, or in production workshops to remove harmful gases. Their application scenarios cover grain processing, pharmaceutical manufacturing, the electronics industry, shopping malls, hotels, office buildings, etc. They are especially suitable for the air - supply and exhaust systems in fire - fighting smoke - exhaust and civil air - defense projects.
2. Excellent Corrosion Resistance and Durability
The galvanized layer on the surface of the air duct can effectively isolate oxygen and moisture, preventing the steel from oxidizing and rusting, thus extending its service life. This characteristic enables it to maintain stable performance in humid, high - temperature, or chemically polluted environments, such as the steam environment in food processing plants or the corrosive gas emission scenarios in chemical workshops.
3. High Strength and Fire - proof Safety
The rigid structure of the galvanized steel plate itself gives the air duct good pressure - bearing capacity, allowing it to withstand the airflow impact of medium - and high - pressure systems. At the same time, the galvanized material has flame - retardant properties, which can effectively delay the spread of fire and provide safety protection for the fire - fighting smoke - exhaust system.
4. Energy - saving, Environmental - friendly, and Low - noise
The smooth inner wall design of the air duct reduces air flow resistance and lowers ventilation energy consumption. In addition, the reasonable structural design can effectively control noise transmission and improve the comfort of the indoor environment.
