Large two-colour cantilever gates. Corrosion protection with zinc spraying, aluminium metal coating

Large cantilever gates with corrosion protection.

We specialise in manufacturing special cantilever gates. We build steel structures with features and equipment that are quite unique in our region. Every gate we manufacture is treated with the Thermal Metal Spray Aluminium process to achieve a long corrosion life. We can even build gates for exceptional entrances with clear widths of 26-36 metres and, if required, with the drive unit hidden in a cabinet. A NO-TOUCH contactless safety edge unit, which prevents the gate from closing onto obstacles, can be fitted to the leading gate leaf on request.

Grit blasting: creating the surface roughness.

The first technological step is removing contamination from the surface of the steel structure. Contaminants can be grease, oil or iron oxide, in other words rust. The required surface cleanliness is achieved by grit blasting, in which abrasive is propelled onto the surface at high velocity. Grit blasting also prepares the surface for the next technological step by producing the required surface roughness.

Thermal metal spraying and surface treatment with an industrial paint coating.

A Zn/Al 85/15 % alloy or pure aluminium was sprayed onto the cleaned surface.

The metal-sprayed surface was then treated with a high-quality industrial paint system: Tikkurila Temacoat epoxy-based sealer primer + Temacoat 50 polyurethane topcoat.
