Hot-dip galvanizing is immersion plating in a molten zinc solution. The production speed is fast, and the coating is thick but uneven. The minimum thickness allowed by the market is 45 microns and the highest can reach more than 300 microns. The color is darker, consumes a lot of zinc metal, forms an infiltration layer with the base metal, and has good corrosion resistance. Hot-dip galvanizing can be maintained for decades in outdoor environments.
Application range of hot-dip galvanizing:
As the resulting coating is thicker, hot-dip galvanizing has better protective properties than electro-galvanizing, so it is an important protective coating for steel parts used in harsh working environments. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, ocean exploration, metal structure, power transmission, shipbuilding and other industries. In agricultural fields such as pesticide irrigation, greenhouses, and construction industries such as water and gas transmission, wire casing, scaffolding, and bridges , Highway guardrails, etc., has been widely used.
