Ventilation ducts are quite common in daily life and have a wide range of applications in both civil and industrial fields. As the name suggests, ventilation ducts are gas delivery pipelines used to reduce the concentration of harmful gases in a space and achieve a livable indoor environment. At present, there are two common materials for ventilation ducts: galvanized steel plate and stainless steel plate. Do you know the differences between galvanized air ducts and stainless steel air ducts?

The main differences between galvanized steel duct and stainless steel duct are as follows:

1. Material: Galvanized steel duct is made of galvanized steel plate, while stainless steel duct is made of stainless steel.

2. Corrosion resistance: Stainless steel ducts have high corrosion resistance and can be used in harsh environments, while galvanized steel ducts have lower resistance to corrosion.

3. Strength: Because stainless steel ducts are made of stainless steel material, they have higher strength and stiffness than galvanized steel ducts.

4. Cost: In general, stainless steel ducts are more expensive than galvanized steel ducts.

5. Scope of application: Select suitable air duct materials according to different usage environments. In some special occasions, such as chemical engineering, hospital operating rooms, and other places with high material requirements, stainless steel air ducts will be more suitable. In some general ventilation equipment, such as ordinary civil buildings, galvanized steel sheet air ducts can already meet the demand.
