Hot-dip galvanizing is the best and most economical way to protect iron and steel against rust, and it ensures a long, maintenance-free service life.
Steel is a nobler metal than zinc, so the zinc provides cathodic protection of the steel. During the hot-dip galvanizing process, zinc and iron react to form an alloy. This acts as an extremely strong adhesion between the metals.
Hot-dip galvanized steel requires no maintenance, and has a service life of 50–100 years, depending on climate conditions. Wet coating, or powder coating, will extend the service life even further.
Due to increased energy costs, we see ourselves having to charge a variable energy supplement.

NOT Varmforzinking has one of the largest hot-dip galvanizing facilities in Norway, with a capacity of 7,500 tonnes per year.
T=460°C, l 13 m x w 1.5 m x h 2.2 m
Zinc content in the crucible: 320 tonnes
Max. dimensions of structures:
l 12 m x w 1.49 m x h 4 m.
The surface of the steel is cleaned through the following pre-treatment process: cleaning in degreasing bath and HCl pickling bath. Next in line is a rinsing bath, followed by a bath containing Florflux, a binding agent to ensure that the zinc bonds with the steel. The steel is then allowed to dry. Finally, the pre-treated steel is dipped in a bath of zinc.
