Hot dipped galvanized steel strip which is widely used in the HVAC industry comprises a high quality zinc layer and passivation treatment, processing excellent corrosion
resistance. Our HDG steel strip with minimized spangle does not contain lead or any other environmentally harmful substance. Similarly, the passivation treatment does
not contain any chromium, and therefore our product is in compliance with EU directives which apply to the household appliance industry. This trend for a greener product
will be gradually extended to the construction and other industries in the near future.
Hot-dip galvanized strips are mainly used in construction, home appliances, automobiles, machinery, electronics, light industry and other industries.
Commonly used steel grades for hot-dip galvanized strips are: general commodity coil (CQ), structural galvanized strip (HSLA), stamped galvanized strip (DQ) deep-drawn
hot-dip galvanized sheet (DDQ), bake-hardened hot-dip galvanized sheet (BH), duplex steel (DP), TRIP steel (phase transformation induced plastic steel), etc.
There are three types of galvanizing annealing furnaces: vertical annealing furnace, horizontal annealing furnace and vertical horizontal annealing furnace.
There are usually two ways to cool a hot-dip galvanized cooling tower: air-cooled and water-cooled.
