Choosing grates for trench drains
A grate’s primary function is to ensure all the surface runoff on a pavement enters the drainage system efficiently. Grates also need to be strong enough to withstand traffic without breaking.
Design criteria for grates
- Liquid intake
- Material durability
- Slot style and aesthetics
- Legal and user requirements for: – Slip resistance – Wheelchairs and walking canes – Bicycle safety – Heel protection
In recent years, the visual design of grates and drainage systems has become more important. ACO has an extensive range of grates with a variety of slot sizes, patterns and construction materials. ACO’s Heelsafe® Anti-Slip grates is a dedicated range specifically designed for pavements where a balance between pedestrian safety and surface liquid collection is required.
