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 ....

sheet industry and automotive industry:

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.
