Deflex 428

Product description

Floor profile made of stainless steel and Nitriflex synthetic material, foreseen for installation on unfinished floor surfaces. An advantage of the profile is the option of using it in aggressive environments (laundry rooms, chemical compound storage facilities). It is characterised by its ability to compensate for movement of its expansion joint both horizontally as well as vertically (slip joint of the inlay with the profile).
The replaceable synthetic material inlay is also available smooth, with reduced accommodation ability (50% of the value for the standard inlay). Specially formed load bearing profiles are masked by an elastomer inlay, which makes them almost invisible. The profile finds use for various kinds of floor finishes, i. e. screed, natural stone, stone imitation, etc.
The profile structure allows replacement of the synthetic material inlay without any need to remove the profile components. It boasts the same design and creates a unified system with the Deflex 399 wall profile. An advantage of the profile is its resistance against aggressive media.
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 is available as flat, a type E corner version and a type EV corner version.
