Product Description
(1) Introduction
Hot-dip galvanizing is a kind of corrosion-prevension measurements on the bolt surface. The Oxidation film easily occurred on the zinc coating in the moist air. It can be isolated with water and air to prevent the chemical etching and the rusting. So the preservative effect is very well as a permanent support. It is applied to conditions which are inflenced by underground water such as road, railway, water conservancy project, etc.
