DHZ Fitness has invested in a new phosphorus cleaning system for its production facilities. As a result, the power tools and fitness machines are particularly well protected against rust during the manufacturing process.

In the phosphoric acid bath a chemical reaction produces an iron phosphate which permanently coating the metal surface. The treatment is used primarily for the supporting elements of the fitness equipment, but also small parts receive additional protection.

The protective layer is suitable for subsequent priming and painting. Because the treatment in the phosphoric acid bath roughens the surface in the microscopic range and can then better absorb the protective primer, which serves as an additional rust protection layer.

Priming and varnishing are carried out directly after the fully automatic cleaning process. For DHZ Fitness, this is another step in order to further improve the already high quality standard of fitness equipment.
