Material

The drain casing, height adjustment collar, lateral adjustment ring, and strainer are made of acrylic nitrite butadiene styrol (ABS). The drain casing is also available in PVC and features a fleece-covered bonding flange. The grate is available in stainless steel 304 (1.4301 = V2A) and anodized aluminum with a brushed copper bronze, brushed brass, or brushed nickel finish.

The Schluter-KERDI-DRAIN grate, in anodized aluminum, must be tested to verify its suitability if chemical exposure is expected. 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 grate is solidly embedded in the setting material and that all cavities are filled to prevent the collection of alkaline water. The anodized layer 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.
The Schluter-KERDI-DRAIN grate, in stainless steel, is roll-formed using 304 (1.4301 = V2A) stainless steel. Therefore, the grate’s appearance differs from those made of anodized aluminum. The stainless steel material can sustain high mechanical stresses and is especially well suited for applications requiring resistance against chemicals and acids.
