Hot Dip Galvanized Products
Hot Dip Galvanized Products
With the development of industry, hot-dip galvanized products have been applied to many areas, the advantages of hot-dip galvanizing corrosion is a long time to adapt to the environment has been widely popular anti-corrosion treatment. Widely used with the power tower, communications tower, railway, road protection, road poles, marine components, building steel structures, substation ancillary facilities, light industry.
Hot galvanized anti-corrosion long years, but in different environments not the same as the anti-corrosion environment: heavy industrial zone 13 years, 50 years of the ocean, the outskirts of 104 years, the city 30 years.
Hot dip galvanizing principle: the iron pieces clean, and then solvent treatment, drying, immersed in zinc liquid, iron and molten zinc reaction to form an alloying zinc layer, the process is: degreasing - washing - pickling - Assisted plating - drying - hot dip galvanizing - separation - cooling passivation.
The thickness of the hot-dip galvannealed alloy layer mainly depends on the chemical composition of the silicon content of the steel, the cross-sectional area of the steel, roughness of the surface of the steel, zinc pot temperature, zinc immersion time, cooling speed and cold rolling deformation.
