ZnAl alloy wire

Zinc-Aluminium alloy wire is particularly suitable for the permanent corrosion protection of steel in maritime applications.

The advantages of
Zinc-Aluminium alloy wires

Highest corrosion protection
With thermal spraying, zinc-aluminium wires offer even higher corrosion protection in maritime, chloride-contaminated environments than pure zinc coatings.
Higher application rates
By using our zinc-aluminium wires, higher application rates can be achieved. Productivity is significantly increased.
Less overspray
The use of zinc-aluminium wires leads to less overspray. This saves resources and costs.
High efficiency & low costs
The use of GRILLO zinc-aluminium wires in thermal spraying enables high efficiency combined with lower costs compared to other materials.

Application areas of
ZnAl alloy wire

Corrosion protection

Zinc-aluminium wire from GRILLO is the solution for durable corrosion protection of steel in maritime environments or those exposed to chloride.

Construction industry & infrastructure

Zinc-aluminium wire is frequently used for thermal spraying of steel parts exposed to chloride. In particular, large components or heat-sensitive steels are permanently protected against corrosion.

Foundry & casting industry

Zinc-aluminium wires are used as corrosion protection for ductile cast iron pipes. The use of this special alloy results in the best possible and long-lasting protection against corrosion in the ground, especially at elevated salinity levels.

Maritime industry

Zinc-aluminium wires are preferred for the protection of steel in maritime applications and low pH environments.
