Hot dip galvanizing：Is an effective way of metal corrosion.Mainly used for various industries of metal structure on facilities. Is will rust removal steel parts into 500 ℃ or so melting zinc liquid, make steel component surface adhesion zinc layer, thus plays the purpose of corrosion.Hot dip galvanizing process:acid washing - water washing -plus help solution - drying - hanging plating - cooling - medicine change - cleaning - grinding - finish.All the ground screw of Leah ground screw the galvanized thickness can reach 85 um-150um. www.ground-screw.com info@ground-screw.comwww.ground-screw.com
