Schlüter-DILEX-STF  Structural movement profile made of aluminium

Schlüter-DILEX-STF is a maintenance free structural movement profile made of aluminium.

The anchoring legs of the profile assembly are connected to the structure with appropriate screw fixings. The covering assembly is then installed, abutting the profile. The sliding telescopic centre section is able to absorb horizontal movements of ±6 mm (with a joint width of 40 mm) or ±10 mm (with a joint width of
50 mm). The lateral joint connections absorb three-dimensional movement. This enables the profile to match the movements of the corresponding structure.

DILEX-STF is designed for use in areas with extensive foot and forklift traffic, e.g. in warehouses and production facilities, shopping centres, airports, railway stations, multi-storey car parks or floor surfaces maintained with cleaning machines.

1. All design specifications of the product must be observed. Select the profile according to the width of the structural movement joint and the height of the covering assembly. The anchoring legs of DILEX-STF may not protrude into the joint.
2. Apply a levelling/anchoring layer of non-shrink cementitious mortar/grout if the substrate is not level or if a height adjustment is needed. Do not allow the mortar/grout to encroach into the structural joint. If necessary, use an on-site joint filler material.
3. Solidly embed DILEX-STF and align the top edge of the profile flush with the subsequent top edge of the joint filler. The profile should not be higher than the tiled surface, but rather up to approx. 1 mm lower.
4. The bilateral bond results exclusively from the mechanical connection with the respective structural element. We recommend the use of concrete anchor bolts such as Heco MMS-plus SS 7.5 x 80 vz, Heco MMSplus SS 10 x 70 vz or equivalent products. The fixing points are distributed with a minimum of 7 fixing points per metre or every 30 cm on both sides.
   
   Note: Do not remove the pre-mounted spacers before or during the profile installation; these may only be taken off when the profile is completely installed!
   
5. The covering assemblies are then installed abutting the profile. Make sure that the top edge of the profile is flush with the top edge of the joint filler and to leave a sufficient space for elastic filler. Full coverage must be obtained between the tile and the profile’s anchoring leg. Always adjoin the uncut tile edge to the profile.
6. Completely fill the space between the top covering and the profile with a neutral crosslinking elastic filler - then peel off the pre-adhered release film immediately.

The profile is available in the following material version:
A = Alu

Material properties and areas of application

Schlüter-DILEX-STF are profiles made of aluminium. For production-related reasons, minor flaws such as tool traces are unavoidable on untreated metal surfaces made of aluminium. Such marks are characteristic of the production process and don't impact product functionality.

The suitability of DILEX-STF should be reviewed based on the anticipated chemical stresses. Aluminium is sensitive to alkaline media. Cementitious materials, in combination with moisture, become alkaline, which may result in corrosion depending on the concentration and length of exposure (aluminium hydroxide formation). For this reason, remove mortar or grouting material immediately from all visible areas and do not cover freshly installed coverings until the adhesive and grout have dried. Solidly embed the profile in the assembly to prevent alkaline water from accumulating in small cavities.
