Metallization
Superior corrosion protection of steel with metallization results in increased flexibility in the surface treatment.

Metallization is the best alternative to hot-dip galvanizing when the resistance and ser-vice life of steel structures are decisive.
Metallization is the best alternative to hot-dip galvanizing when the resistance and ser-vice life of steel structures are decisive.
Metallization is well-suited for steel structures which cannot be hot-dip galvanized for various reasons, such as steel structure size, design, heat tolerance or the steel type itself. Metallization can be used as the only surface treatment but is usually followed by a paint process with several layers. The structures will be cleaned by means of air-blow cleaning before the metallization process. This will ensure the desired surface finish to increase the adhesion, strength and overall service life of the metallization.
The zinc is applied by means of an arc at high temperatures using the same principles as spray painting. The zinc pistol's manual application of metallization can provide the desired zinc film thickness with great accuracy. The application is more flexible than hot-dip galvanizing and can precisely cover inaccessible places - such as bearing fits or threaded holes.
The quality will then be inspected visually and the film thickness is decided by a film thickness meter to ensure optimum quality and a uniform feel. Film thickness is measured in my (µ).

Every day, DOT is meeting the high requirements for corrosion protection which is delivered as is or subsequently painted. Many items are painted after metallization which also enhances corrosion protection in addition to the practical, aesthetic and functional purposes. Paint is chosen in accordance with the item's end use and the customer's wishes for colour codes and corrosion categories.
Entrusting the entire job of metallization and painting to DOT will provide the customer with one supplier for the entire surface treatment. DOT assumes the overall responsibility for both metallization and painting which ensures the best conditions for the final result.
DOT is synonymous with reliability of delivery and ensures the perfect quality and price

Agile and strong surfaces Zinc is a durable material in constant movement.
This means that the zinc film forms an impact-proof and agile surface – which is useful for particularly exposed items. As a result, scratches on the zinc surface may disappear over time as zinc is a live natural material. Metallization allows the accurate zinc film thickness to be achieved with great precision.
- Customised film thicknesses with uniform surfaces
- Tension surface for friction joints
- Direct production after metallization
- Cathodic protection / quality assurance
