Open area sized for flow
Drainage grates need enough open area for the expected runoff, not just enough steel to cover the trench. Slot width and bar spacing are chosen around water volume and debris.
Drainage Grates in Innisfil are custom-fabricated metal grates engineered to carry traffic loads while providing drainage, access, or debris control. The Grate Guys custom-fabricates every piece to your spec, load class, and finish, then ships and installs across Innisfil, the GTA, and Ontario.
Fabricated in Canada in our Toronto shop, with Canadian steel.

Drainage grates need enough open area for the expected runoff, not just enough steel to cover the trench. Slot width and bar spacing are chosen around water volume and debris.
The grate has to sit on a frame or concrete ledge that can carry traffic. Weak bearing edges lead to rocking, noise, and broken concrete around the drain.
Forklift tires, vehicle tires, pallet jacks, and pedestrian shoes all cross grates differently. Bar direction and spacing are selected so wheels do not drop into the openings.
Drainage systems collect sediment. Lift-out sections, manageable panel weights, and pry slots let crews clear the channel without wrecking the grate.
