1. Trench & Grate Size
The size of the trench determines how much water can be captured and held while released through the outlet. While the number and size of outlets changes the release rate of water and is the primary factor in how much water can be carried away, larger trenches can naturally hold more while awaiting discharge. The following trench and grate sizes are carried as stock lines.
2. Load Rating
The types of load that are expected to traverse a trench grate are important in helping choose the most appropriate trench grate.
Typically, residential settings will require a class B (light duty) trench grate. Commercial and industrial sites typically require a class D (heavy duty) trench grate.
