Metallization

Metallization with pure zinc or a zinc-aluminium alloy, provides anti-corrosion protection for all types of steel and cast iron.

The ease of use and technical performance of this process makes it an attractive and economical option.

It is sometimes used instead of galvanization for articles that are large or involve complex geometry, or that carry a risk of distortion.

In metallization the zinc is melted by the flame or arc of a spray gun and attaches itself to the steel or cast substrate that has been cleaned by shot blasting (to level Dsa 3, ISO 8501-1).

This operation is defined by NF EN 22063/ISO 2063 and NF P 24-351 for the thickness of the coating as a function of the final environment. The lifetime of the anti-corrosion coating depends on the thickness of the coating.

Preparation by shot blasting is essential before metallization.

A distinction should be made between metallization and zinc powder primer treatments that are sometimes applied without shot blasting.
