Harmer Stainless Steel Channel Applications
Harmer Modular 135 channel is designed for direct connection to 110mm pipework, where additional sump gully is required, please contact Harmer Technical for options. The Modular 135 channel system is designed for installation within a concrete floor.
Installation can be done prior to the pouring of the concrete floor or within a pre-prepared shuttered trench. When preparing a trench, it’s important to observe the following dimensions to ensure correct reinforcement for load class rating.
The standard channel edge is for light duty applications, with a load class rating of A15, for use with tiled, concrete and resin flooring. A PVC infill can be purchased separately, to increase the load class to B125.
