Surface and corrosion protecon
Depending on the ambient condions, the surface and corrosion protecon system (called
OKS) oers tailor-made soluons for opmum protecon.
Various surface coangs ensure reliable funconing even at high air humidity, in outdoor
installaons, or in the presence of atmospheric contaminaon. Any color from the "RAL
Classic" collecon can be chosen for the top coat.
For indoor installaon in buildings and if no special corrosion protecon is required, the
products are also available unpainted (without surface and corrosion protecon system).
Without OKS (unpainted):
The aluminum parts are uncoated and cast iron parts primed with gray paint.
Slight color dierences between the components are possible.
