Trench Grates

SVC's trench grates and trench channel sets have a simple, modular design that allows long linear drainage channels to be created. Simply install the trench grating frames or channels end-to-end to create the desired length, then backfill or pour concrete around the frames to set them into place. Finally, the 1m grate segments are bolted down into the steel frames to complete the system.

Trench drains are used to intercept and collect surface water over a long, continuous line, as opposed to at a singular point. The water is captured and diverted into the underground drainage system, avoiding water pooling at the ground level.

Common drainage trench applications include low points in front of garage doors, across large paved areas, at the base of retaining walls, around carparks or at the entry to commercial buildings.

In general, the standard forgebar or weaved pattern in SVC's stormwater grating range is rated as bike-safe, meaning bicycle or wheelchair wheels can safely travel over the grate surface without getting caught or stuck. The grate apertures (openings) of bike-safe grating designs are typically too large to safely accommodate high-heeled shoes such as those with a stiletto heel.

In certain applications, pedestrian areas may specify "heel-safe" or "heelproof" grates, which have smaller openings to prevent high heels from getting caught. Out of SVC's stormwater grate offerings, only our Pedestrian-Safe Grates are classed as "heel-safe" and are suitable for high-heeled shoes.
