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.
