Schlüter®-TREP-SE is based on a V2A stainless steel support profile (material 1.4301 = AISI 304), which is made from stainless steel strips in a roll-profiling process.
Schlüter®-TREP-S / -B have aluminium support sections. All three profile types include a tread insert consisting of a rigid PVC bottom section and soft PVC slip resistant surface. The width of the Schlüter®-TREP-SE / -S tread surface is 26 mm; the Schlüter®-TREP-B tread surface is 52 mm. The support section includes a trapezoid perforated anchoring leg for securing the profile in the tile adhesive.
Material properties and areas of application
In special cases, the suitability of a proposed type of profile must be verified, based on the anticipated chemical, mechanical and/or other stresses.
Schlüter®-TREP-SE, with a support section made of stainless steel, is particularly well suited for areas of application where resistance to chemicals and acids is necessary and where alkaline exposure is anticipated, e.g. through the reaction of water with cementitious materials.
Schlüter®-TREP-S / -B, with aluminium support sections, are resistant to chemical stresses commonly encountered in tiled coverings on stairs. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and time of exposure) may result in corrosion. Therefore, it is important to ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water.
