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
- Loading
- Locking
- Slot style and aesthetics
- Legal and user requirements for: – Slip resistance – Wheelchairs and walking canes – Bicycle safety – Heel protection
