They provide additional protection against humidity and contamination.
The profile is composed of load-bearing aluminium components, affixed to the surface, connected with washers made of Nitriflex synthetic material to the top aluminium cover.
An option, available at extra charge, is the possibility of executing the top cover of stainless steel.
