Hot-dip galvanizing

Affordable and environmentally friendly

Hot-dip galvanizing is the most affordable and effective method for protecting iron and steel against corrosion, ensuring a long lifespan without the need for maintenance.

NOT is one of the first players in the industry to use low-carbon zinc. This is supplied by Boliden in Odda – which has the world’s most climate-efficient zinc production. The zinc, extracted using clean energy, significantly reduces the carbon footprint compared to other alternatives available in the market.

Zinc – protective, healing, reliable, and essential.

A zinc-treated surface has an exceptionally long lifespan and self-healing properties. If an area is damaged, the zinc reacts, creating a galvanic element that stops rust formation – truly ingenious!

In addition to serving as a versatile and effective surface treatment, zinc plays a crucial role in various aspects of our lives. It finds application in everything from airplanes and cars to the IT industry and healthcare. This knowledge offers reassurance, as zinc is not harmful to humans, animals, or plants.

Pre-treatment

Black steel

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..

Painted/primed steel

Painted/primed steel must be sandblasted prior to pre-treatment. The surface of the steel is cleaned through the following pre-treatment process: cleaning in 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.

We have two overhead cranes with a lifting capacity of 12.8 tons per crane. The maximum lifting capacity for structures is 25.6 tons.
