Galvanization treatment is one of the most poplular anti corrossion treatment for its high performance and cost efeective.
In nature environment, the most offen happened corrosion type is electircchemical corrossion, When the electricchemical corrossion happens, the galvanization layer will function as positive plate, to reach the popurse of protect the steel plate.Further, due to the reaction of zinc and oxygen, a zinc oxide layer will appear on the surface of the plate, and which is dense and inertia. The layer will obviously extand the life span of the steel plate.
High galvanization steel means the steel plate which galvanization is larger than 275g/m2. Such as 350/430/500/600 g/m2. Usually apply to port project, high humiditt mountain area, industrial air pollution area and some acid rain happens region.
We SRON adopt high quality high strength gavalnized steel plate which is imported from Korea POSCO steel.
A high quality hign galvanized steel plate has following features:
1. Surface is smooth and flat, no defact such as crease or sunken.
2. Zinc content is high purity. No black spot.
