Always galvanized

EAB´s steel doors are always galvanized in the basic model. A paint system with the equivalent protective effect would take one week to apply.

As an optional extra, the doors can be supplied with pvf2-lacquered profiled sheet, available in a number of standard colors and others in accordance with the EAB color range. In corrosive environments such as those close to coastal areas with salt water, washing installations, paper mills, livestock, etc. the life of the door may be increased by painting the basic galvanized model.

Surface treatment


Option 1
Hot-dip galvanisation gives complete coverage and double protection. Dipping in molten zinc gives a coating on all surfaces of the door leaf, including inside the tubular pipe sections. Furthermore, hot-dip galvanisation also makes the coating extra thick on corners and edges, instead of thinner as is the case with painting. 

Hot-dip galvanisation protects steel in two ways. Firstly, the zinc coating corrodes very slowly and thus gives the door a long life. Secondly, zinc provides cathodic protection if the coating is damaged. If there are drill holes, clipped edges or splits, a galvanic element is formed with zinc as the sacrificial anode, protecting the steel from corrosion.


Option 2
Lining with powder-coated steel sheeting on a hot-dip galvanised frame. As an optional extra, doors are delivered with polyester powder-coated profiled sheeting in a range of standard colours - see the colour chart on the left.

Polyester is one of the most common coating systems for coated construction sheeting on the market, and a well-proven exterior paint with good gloss and colour retention and good malleability which fulfils the demands of good construction sheeting. Common uses include facades and external roofs in normal environments.

Option 3
Surface treatment of steel doors for very corrosive environments such as coastal environments with salt water, car washes, paper mills, animal enclosures, etc. The lifespan of the door can be extended with a coat of paint on the hot-dip galvanised basic finish.

This type of painting places great demands on pre-treatment and colour choice, usually including blasting, priming with special primer of around 60 μ and a 2-component top varnish of 40-50 μ.

Since requirements vary according to environment, they should be assessed for each individual item. If you want to paint on a hot-dip galvanised surface without prior blasting, the surface must be aged, i.e. the door can only be painted after two years.
