Bekaert offers a wide range of active, passive or combined corrosion resistant coating solutions for any application and any environment. In terms of active corrosion protection, we offer Bezinal®, our own range of zinc aluminum coatings. Bezinal® offers the best performance in terms of corrosion and heat resistance, durability and processability.
Bezinal® coated wires resist corrosion 2 to 6 times longer in heavily polluting corrosion tests than hot-dip galvanized wires and last up to 8 times longer in heavily polluted areas**. This is thanks to the formation of the dense and high quality passivation layer that is mainly formed by aluminum oxides.
** Based on salt spray tests and Kesternich tests
Zinc-alloy coatings also offer cathodic protection of uncoated areas of the steel (e.g. cut-ends or scratches). The active coating generates an electrical current which reverses (counteracts) corrosive attack of the steel.
Regular hot-dip galvanized (HDG) wires tend to experience alloy layer growth when exposed to higher temperatures. This alloy layer is the interface between the metallic coating and the steel wire. It generally contains the elements of the top coating combined with iron from the wire core. However, coatings of the Bezinal® range are immune to this phenomenon due to an inhibiting action of aluminum.
To ensure the good quality and performance of our products, Bekaert constantly performs various standardized tests for product development or on the specific request of our customer. Bekaert performs corrosion tests from their own ISO 9001 certified laboratories and has them confirmed by various independent research facilities across the globe.

Situation Skiers count on safety when they go up the mountain
Solution In close cooperation Bekaert developed superior quality wires that meet the technical customer requirements of ropeway constructors
Result The customer handles the production of the cables, but also on-site weaving (or splicing) and installation. The cables have a life expectancy up to 40 years
Situation Ultra-strong and length-stable material is needed to reinforce synchronous belts which drive wind turbine blades.
Solution A high-quality steel cord comprised of 83 twisted wires.
Result Optimum tensile strength, length stability and adhesion with the rubber belt providing the wind turbine manufacturer with a substantially lighter, maintenance-free and space-saving solution.
