Material: Galvanized iron spiral round ducts are typically made from galvanized steel sheets, formed into a cylindrical shape with spiral-seam construction.
Advantages:
Corrosion Resistance: The zinc coating on galvanized iron provides excellent resistance to rust and corrosion.
Durability: Galvanized iron is known for its strength and durability, ensuring a long service life.
Cost-Effective: It is generally more affordable than some other materials.
Space-Efficient: Round ducts are space-efficient, making them suitable for installations with limited space.

Material:Double-wall spiral round ducts feature an inner duct and an outer shell, often both made from materials like galvanized iron or other metals.
Advantages:
Airtight Construction: Double-wall ducts minimize air leakage, ensuring conditioned air remains inside the duct and improving energy efficiency.
Durability: The dual layers offer added strength and protection, making them suitable for demanding applications.
Noise Reduction: The double-wall design can provide noise reduction benefits, contributing to quieter HVAC operation.
