What are the advantages and disadvantages of galvanized air duct and stainless steel welded air duct?

Galvanized air duct and stainless steel welded air duct have their own advantages and disadvantages, as follows:

A, galvanized air duct

Advantages:

Low cost: Compared with stainless steel welded air duct, the material cost and manufacturing cost of galvanized air duct are relatively low, which is suitable for projects with limited budget.

Lighter weight: easy to install and carry, reducing the construction difficulty and labor cost.

Good corrosion resistance: In general, the galvanized layer can provide certain corrosion protection and prolong the service life of the air duct.

Disadvantages:

Corrosion resistance is limited: although it is protected by galvanized layer, galvanized air duct is easy to rust and reduce its service life in humid and corrosive environment.

The strength is relatively low: it is not as strong as stainless steel welded air duct, and may be easily deformed when subjected to greater pressure or external force.

The appearance is relatively poor: the surface texture is not as smooth and beautiful as the stainless steel welded air duct.

Second, stainless steel welded air duct

Advantages:

Excellent corrosion resistance: it can maintain good performance in various harsh environments, is not easy to rust and has a long service life.

High strength: able to bear large pressure and external force, not easy to deform, ensuring the stability of ventilation system.

Beautiful and generous: it has a smooth surface and a modern appearance, and is suitable for places with high decoration requirements.

Good hygienic performance: easy to clean and disinfect, which meets the hygienic requirements of food, medicine and other industries.

Disadvantages:

Higher cost: The cost of stainless steel material and welding process is relatively high, which increases the investment of the project.

Heavy weight: installation and handling are relatively difficult, requiring more manpower and equipment.

High welding requirements: strict welding technology is required, otherwise welding defects will easily occur and affect the quality of air ducts.
