The profiles are available in the following material versions:
- E = stainless steel
- V2A, material no. 1.4301 = AISI 304
- V4A material no. 1.4404 = AISI 316L
They are made of stainless steel produced in a rollforming process and feature trapezoid perforations on the anchoring legs. The movement zone of Schlüter-DILEX-HKS consists of an 11 mm wide, highly flexible synthetic rubber insert.
Material properties and areas of application
In special cases, the suitability of the intended profile types must be verified based on the anticipated chemical and mechanical stresses. The information provided below is intended as a general guideline. The support profiles of Schlüter-DILEX-HKS are made of stainless steel V2A (material no. 1.4301 = AISI 304) or V4A (material no. 1.4404 = AISI 316L) and are particularly well suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals such as acidic or alkaline media or detergents. Depending on the anticipated chemical stresses, customers can choose between the alloy materials 1.4301 (V2A) or 1.4404 (V4A). The use of V4A is recommended if consistent exposure is expected, for example in the case of swimming pools (fresh water).
Even stainless steel of quality 1.4404 is not resistant to all chemical stresses such as hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. In certain cases, this also applies to seawater pools. Special anticipated stresses should therefore always be verified in advance.
The flexible movement zone of Schlüter-DILEX-HKS is made of soft synthetic rubber. This rubber is resistant to most chemicals encountered in tiled or natural stone environments. It is also resistant to fungi and bacteria.
The insert is resistant to temperatures ranging from -60 °C to +100 °C. The synthetic rubber can be heat bonded to extend the profile length.
