Our thresholds are made of 1-1/2” x 5” extruded aluminum with 1” high density polyethylene plastic on top. It fastened to the floor with the same anchor bolts used on the rest of the boards. They will take heavy machinery driving over them and are not loosened by freezing water or prolonged use.
We supply door bumpers at the machine gate doors and all the man doors to protect your boards from the abuse we know they will get.
