Corrosion protection is a question of trust as only time will tell if the work has been carried out properly. We at DOT vouch for our surface treatment, every time. Hot-dip galvanizing is used for agricultural machines, housing equipment, hardware, wind turbines, facades, balconies, stairways, etc.
There is no better corrosion protection of iron and steel than hot-hip galvanizing. Steel is one of the building blocks in the structures of modern construction where high demands of quality and service lives are crucial.
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. This creates a strong metallic bond ensuring the durability of the protection and creating a cathodic protection of areas which are not covered by zinc. Unlike paint which adheres to the surface of the steel. This galvanizing creates a hard-wearing and resistant surface with extraordinarily long life and is almost maintenance free.
The hard-wearing galvanizing sustains transport and handling as zinc is a robust material. When the item has been hot-dip galvanized, it is subjected to careful quality controls ensuring the customer the optimum result and service life. DOT’s hot-dip galvanizing and zinc film thickness comply with the quality requirements of ISO 1461.
