Metallization, also called thermal spraying, is the application of
a layer of zinc on a material. This layer offers an adequate protection
against corrosion. Especially when your product will be used or placed
outside, metallization is recommended.
After the material is cleaned by sandblasting
it (SA2,5), the zinc is applicated by wire flame spraying the zinc
on the surface of the material. The zinc wire is feeded into an oxygen-fuel
gas combusion flame, melted and then atomized by a blast of compressed
air (see picture below). The result is a long-lasting rust-preventing
When metallization is not possible because of technical reasons, we
let it (hot dip) galvanize.
Especially products that have to be galvanized inside as well as outside,
we contract out.
