The bearing bars are placed in one direction on a frame, while the cross bars are perpendicularly stacked on top of the bearing bars and spaced out to create a flat surface that can be walked on.

Some trench covers have openable lids to inspect the trench, while others are fixed. These trench covers have holes to allow water and air to pass.

  • What kind of surface is underneath your work area? If it’s concrete, then a press-locked system will be your best option. If it’s asphalt or asphalt/concrete mix, then welded systems will be better suited than press-locked ones.
