• Material & coating
Sometimes, the elements of the project will be exposed to outdoor or wet conditions for a long time. If so, except for

○ Electro-galvanized. it is a zinc electrolytic process that adding a thin coating to the carbon steel nails.
Electrogalvanizing coating can withstand dry and low-corrosion applications for a few more months or

○ Hot dipped galvanized. It is an effective way of metal corrosion, mainly used for metal structure on the
