1. Price: The price of galvanized steel grating is low, and the price of hot-dip galvanized steel grating is 3-4 times higher than that of galvanized steel grating.

2. Environmental pollution: Hot dip galvanizing produces less "three wastes" than electroplating, and has a smaller impact on the environment.

3. Production efficiency: The production efficiency of hot-dip galvanizing is particularly high, and the time for parts to stay in the hot-dip galvanizing tank is relatively short.

4. Usage: The hot-dip galvanized steel grating has a thick galvanized layer, fine crystallization, uniform and no pores, good corrosion resistance, slow corrosion in acid, alkali and other mist, and can effectively protect the steel substrate. It has a longer service life than electrogalvanizing and can be used for 40 years.
