The aluminium and brass serrated tee bars as standard are 9.5mm wide and are installed at 13mm centres. The small gap between each of the tees provides a visually appealing product and allows dirt, dust and water to be trapped at the base of the grid, preventing the tracking of material or water onto floor surfaces. The grids can then be easily vacuumed to remove any buildup of dirt or debris.
The narrow 3.5mm spacings between the tees are designed not to interfere with traffic movement over the system and it is recommended that all Lathamgrid grid mats be installed with the longitudinal bars left to right across the doorway as shown below.
