Our Galvanised Steel Spiral Ducting is widely used in European, American and Middle Eastern HVAC projects for commercial buildings, offices and hotels. Made of high-quality hot-dip galvanized steel strip with automatic spiral forming technology, the duct features smooth wall surface and low wind resistance, improving ventilation efficiency and reducing energy consumption.
The spiral occlusal structure ensures excellent air tightness without air leakage. The thick and uniform galvanized layer with anti-corrosion passivation treatment realizes rust and high-temperature resistance. Easy to clean and maintain, the product fully complies with European and American HVAC industry standards and supports multi-specification customization, becoming a reliable choice for high-end overseas ventilation projects.
