HOT DIP GALVANIZINGIn the everyday life you can find galvanized steel everywere, but the fact
is that the galvanized steel is hardly considered by the public.
Possibility for use:
architecture: grid, railing, garage door, lift...
building steel: bridges, houses.........
Navigation & water building : harbor constructions,
sluices......
mining: cage, conveyorecar, conveyor - tower ......
electrical engineering: transmission tower, switch gear,
....
mechanical engineering: heat exchanger, ventilation ....

Material zinc
Zinc is a bluish resplendent metal with relatively low
melting point of 419,4 C
At temperatures closely over the melting point, zinc have
a characterised good flow behavior. In the liquid status it reacts easily and forms with iron a
set of metallic connections, which adhere usually firmly
on the surface and does not form to thick layers.
Zinc has a good corrosion protection in the pH area of
6 - 13. In acidic and alkaline media is Zn lower steady.
