Deflex 500/na

Technical description

This water-tight profile is made up of aluminium form profiles, a Nitriflex synthetic material inlay and protective covers made of stainless steel. It is used for the execution of expansion slits in surfaces with any kind of finish. It is characterised by an aesthetically pleasing design and full water tightness. The profile finds use in parking lots, multi-storey parking lots, underground parking lots, pedestrian overpasses, ramps, swimming pools and in wet rooms where water resistance is required. It may in particular be used for floors made of polyurethane or resin. The profile is resistant to traffic salt, aggressive agents (i. e. petrol) and other external influences.

The synthetic material inlay is joined into one section through welding. Should it become necessary, the sealing inlay may be replaced during site operation without damage to the neighbouring floor surfaces or the top layer.
It is also possible to replace the protective stainless steel covers. The stainless steel covers may in addition be executed as non-slip covers.
It is also possible to execute complicated water-tight mounting shape profiles allowing the execution of all kinds of processing work at the site.
The profile is characterised by an optimum fusion of such parameters as high load bearing capacity and the ability to take on high shifts (expansion slit movement compensation) against the visible profile width after installation, while full water resistance is maintained.
The profile conforms to fire resistance requirements for class E according to standard PN-EN 13501-1, according to which the products are able to stand up to the effects of a small flame without significant flame spreading - for a short time.
Profile available in flat and corner form.
