Hot dip galvanisation + powder coating

Weland's roof safety products are always hot dip galvanised. In certain cases, the customer wants the roof safety products to "blend into the environment" on the roof.

In order to meet these wishes, we also stock most of the products in powder coated versions, in brick red, black and grey. The powder-coated products have particularly good corrosion protection, as they are hot dip galvanised before being painted. This means that even if the paint is damaged, the steel will not rust.

Hot dip galvanisation

Hot dip galvanisation – the maintenance-free corrosion protection with an unsurpassed service life.

Hot dip galvanised steel has very long-lasting corrosion protection. In a normal environment it can have a service life of 60-80 years. The zinc that is precipitated out with the rain water forms compounds that do not dissolve easily, which in turn has a negligible impact on the environment.

All other surface treatment of steel creates the need for maintenance, and during its lifecycle this has a significant impact on the environment. The most important reason for selecting hot dip galvanisation is the considerable increase in the maintenance-free service life. It is there that the really great environmental benefit can be achieved!

What is hot dip galvanisation?

Products made of steel that are to be protected against rust are immersed in a zinc bath, containing melted zinc at a temperature of approx. 455°C. When the steel comes into contact with the liquid zinc, a reaction occurs between the metals. Steel and zinc alloy with each other, and the adhesion is perfect.

We perform hot dip galvanisation in accordance with standard SS-EN ISO 1461, which corresponds to C3 in BSK07.

Zinc layer – service life

On our hot dip galvanised products, a service life of 60-80 years can be anticipated. All other surface treatment
of steel creates the need for maintenance, and during its lifecycle this has a significant impact on the environment. The most important reason for selecting hot dip galvanisation is the considerable increase in the maintenance-free service life. It is there that the really great environmental benefit can be achieved.
