How environmentally friendly are galvanized ventilation ducts and do they meet current green buildin

The environmental friendliness of galvanized ventilation ducts is reflected in the entire process of production, use, and recycling, fully meeting the requirements of the "Green Building Evaluation Standard" (GB/T 50378), making it an ideal choice for green building ventilation systems. The production process adopts hot-dip galvanizing technology, with uniform adhesion of the zinc layer and no excess pollutant emissions. The production process of galvanized steel plates has achieved large-scale clean production with low energy consumption; Compared to the harmful gases generated during the production process of plastic pipes, galvanized pipes have a smaller impact on the environment. During use, galvanized pipes themselves do not release volatile organic compounds (VOCs) such as formaldehyde and benzene, which do not pollute indoor air and ensure human health; Its excellent ventilation efficiency can reduce the energy consumption of air conditioning, fans and other equipment, reduce carbon emissions, and meet the energy-saving requirements of green buildings. In the recycling process, galvanized steel plates can be 100% recycled and reused. During the recycling process, the zinc layer can be separated and recycled separately, achieving resource recycling. Compared with the difficulty of degrading plastic pipes and recycling composite pipes, galvanized pipes have significant environmental advantages. In addition, it has a long service life, reduces construction waste caused by pipeline replacement, and further enhances the green and environmental protection level of buildings, so it is widely used in green building projects.
