• anodised aluminium (-FLAE),
• stainless steel (-FLE), and
• brushed stainless steel (-FLEB).

Material Properties and Areas of Application:
The suitability of a proposed type of profile must be verified based on the anticipated chemical, mechanical, and/or other stresses.

Schlüter-TREP-FL is intended for use in residential or similarly used interior applications with low foot traffic. The information provided below is intended as a general guideline.

Schlüter-TREP-FLAE, made of anodised aluminium, has an anodised surface finish that will not change under normal circumstances. The surface must be protected against abrasion or scratching.

Cementitious materials, in conjunction with moisture, become alkaline. Since aluminium is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and duration of exposure) may result in corrosion (aluminium hydroxide formation). For this reason, remove mortar or grouting material immediately from all visible areas and do not cover freshly installed coverings with foil. In addition, ensure that the profile is solidly embedded in the setting material to prevent water from accumulating in small cavities.

Schlüter-TREP-FLE/-FLEB is made of roll formed stainless steel V2A (material no. 1.4301). The profile structure therefore differs slightly from the appearance of the extruded aluminium versions.

Stainless steel is particularly well suited for applications that, in addition to heavy mechanical stresses, require resistance to chemicals such as acidic or alkaline detergents. Even stainless steel is not resistant to all chemical stresses, and may be affected by hydrochloric and hydrofluoric acid or certain chloride and brine concentrations. Special anticipated stresses should therefore be verified in advance.
