ArcelorMittal Industrial Wire enjoys a worldwide reputation for its corrosion-resistant Crapal® coatings.
Crapal® technology combines zinc, aluminium and, in the case of Crapal®Premium, magnesium to provide a highly protective anti-corrosive coating.
How does Crapal® work?
The base steel within every Crapal® wire product is a high grade drawn steel wire. We take what is already a superior grade steel wire and coat it in our Crapal® protective anti-corrosive zinc and aluminium alloy.
The alloy adheres to the steel base wire and protects it against extreme weather conditions, hot, cold, dry and humid and in diverse locations including coastal and highland sites. Zinc gives an active and sacrificial protection while aluminium provides passive protection in covering zinc and significantly slowing down its sacrificial reaction.
Excellent adhesion with no peeling, flaking or cracking.
Durable and smooth surface.
Consistent concentricity of the coating.
Continuous protective layer encapsulates the steel base wire
Outstanding performance under thermal stress
Excellent protection against the cathodic corrosion of cut ends
Total protection of welded joints - No requirement to galvanise after manufacture.
