Corrosion resistance for window and door hardware
Anyone who installs premium windows and doors wants long-lasting quality. This comes as standard at Roto. To meet our own high quality standards, alongside strict quality checks in development and production, we also rely on components of perfect quality. The surface treatment of our hardware components is an essential part of this.
Coordinated processes in development and production ensure the optimal surface treatment for hardware components.
In use worldwide
The particular challenge we face is that our hardware is used all over the world. This means that it has to withstand a range of different climatic conditions and environmental influences - whether it’s in industrial urban areas with high pollution levels, in coastal regions where the air is very salty, or under the effect of specific vapours like chlorine in swimming pools or sulphur in cattle sheds.
Tailored to requirements
Roto components have a corrosion-resistant surface which permanently protects them against external influences and offers excellent durability and functionality. Thanks to the incredibly hard and abrasion-resistant Roto Sil Level 6 surface, even connection elements and sliding elements subject to high strain are effectively protected against corrosion.
Protection for all base materials
The surfaces of various different base materials are coated: steel, zinc die-cast, aluminium cast, aluminium and a variety of types of PVC. Specially coordinated processes make it possible to perfectly adapt these materials to customer requirements.
SPC special surface
While Roto Sil as a standard surface already achieves class 5 in accordance with DIN EN 1670, the SPC special coating is used as part of a two-stage process for particularly harsh ambient conditions, for example in coastal areas or in swimming pools. This surface’s resistance to chemicals is based on the binder matrix which also ensures the strength and stability of the coating. The chemical resistance and not the corrosion protection is usually the decisive factor in whether or not SPC is suitable for very specific ambient conditions.
