Material

In special cases, the suitability of a proposed type of material must be verified based on the anticipated chemical, mechanical, and/or other stresses.

Schluter-SCHIENE, in stainless steel, is roll-formed using 304 (1.4301 = V2A) or 316 L (1.4404 = V4A) stainless steel.  Therefore, the profile's contour differs slightly from those made of extruded brass or aluminum. The profile can sustain high mechanical stresses and is especially well suited for applications requiring resistance against chemicals and acids; for example, in the food industry, breweries, dairies, commercial kitchens, public swimming pools, and hospitals. 316 L stainless steel offers even higher corrosion resistance when compared to the 304 stainless steel.

Schluter-SCHIENE, in solid brass, sustains high levels of mechanical stress; for example, as edge protection for movement joints in coverings exposed to industrial traffic. Brass is resistant to most chemicals used in tiled environments. Solid brass that is exposed to air will oxidize, resulting in a natural patina. If exposed to moisture or aggressive substances, heavy oxidation and spotting may occur.

Schluter-SCHIENE, in aluminum, must be tested to verify its suitability if chemical stresses are anticipated. Cementitious materials, in conjunction with moisture, become alkaline. Since aluminum is sensitive to alkaline substances, exposure to the alkali (depending on the concentration and duration of exposure) may result in corrosion (aluminum hydroxide formation). Therefore, it is important to remove mortar or grout residue from visible surfaces. In addition, ensure that the profile is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water.

Schluter-SCHIENE, in anodized aluminum, features an anodized layer that retains a uniform appearance during normal use. The surface, however, is susceptible to scratching and wear and may be damaged by grout or setting material. Therefore, these materials must be removed immediately. Otherwise, the description regarding aluminum applies.
