Hot-dip galvanizing
Our corrosion protection stands the test of time and requires minimal maintenance.
Minimal maintenance - maximum protection
Hot-dip galvanizing is the best corrosion protection and is used for agricultural machinery, barn fixtures, fittings, wind turbines and facades, among others.
You can rely on us to ensure that your surface meets all quality requirements. You can do this because of our experience — and because we have invested in quality equipment. For example, we have one of the largest vessels in Northern Europe with 450 ºC liquid zinc, which ensures an optimal chemical bond between the zinc and the steel.
The treatment creates cathodic protection for areas not covered by zinc, which provides a highly durable and resistant surface. After the item has been hot-dip galvanized, accurate quality checks are made to double-check the result.
DOT's hot-dip galvanizing and zinc layer thickness meet the quality requirements of DS/EN ISO 1461.
A fleet of own trucks
As a customer of DOT, you become part of a circuit where the delivery and production process is geared to the reality and needs of your company.
See the driving scheduleHow we hot-dip galvanize
Hot-dip galvanizing is a process where the item for galvanizing is cleaned of grease, oil, mill scale, rust and other impurities. Hot-dip galvanizing is carried out by immersing the item in one of the largest baths of molten zinc in Northern Europe at 450°C creating a strong, chemical bond between steel and zinc.
Large and small items - same quality
We can supply everything from very small brackets to colossal steel structures of up to 15 tonnes or a length of 22 metres.
With a large lifting capacity over one of the largest zinc pots in Northern Europe, our production facility can handle blanks and capacities for all customer needs. Even if the workpiece is larger than the pot capacity, we can use different techniques during the handling phase to ensure delivery.

When the balcony is not just the balcony, but the building itself
We have hot-dip galvanized and delivered many balconies in our approximately 40-year lifespan. Alot. But it's not every day that we create balconies that mean as much to the form and function of the building, and to the reception of the citizens, as was the case with Kaktus Towers.
