Difference between electro-galvanized and hot dip galvanized

1. The zinc layer:Electro-galvanized zinc layer generally in the 3 to 5 microns, special requirements can also reach 7 to 8 microns. The thickness of hot dip galvanized zinc layer can achieved more than 50 microns, the maximum can reach 100 microns.

2.Salt spray test distinction: general electro-galvanized sail spray test in less than 10 hours, but hot-dip galvanizing of the salt spray test can be reached in about 30 hours.

3.Product use: The electroplating’s nails generally used in the packaging of some more sophisticated electronic products, appliances, etc. And hot dip galvanized nails used in bad environment is relatively poor, such as corrosion of air and liquid; relatively humid, such as beach houses and parapets connection.
