Deflex 500/ek

Technical description

This water-tight profile is made up of aluminium form profiles, to which a joining rod is attached, 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. Thanks to the use of the joining rods affixed to the aluminium profiles, the profile may be installed together with the structure's reinforcement, and it is concreted together with the structure. Thanks to this solution, the profile is completely joined with the structure it is working together with, while maintaining full water resistance.
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. The inlay is also available in a version with long bands. It is also possible to replace the protective stainless steel covers.
The profile is resistant to traffic salt, aggressive agents (i. e. petrol) and other external influences.
The manufacture of complicated, water-tight installation form profiles is possible.
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 stainless steel covers may in addition be executed as non-slip covers.
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.
