SlipNOT® steel road plates are ideal for high traffic areas that can become slippery with water, oil, gasoline and other substances. SlipNOT® traffic plates can be used to cover open trenches, sinkholes, and areas of road construction. They can quickly restore a jobsite back to pre-project conditions by bridging open excavations and trenches dug for drainage, cables, gas mains or water mains. SlipNOT® non-skid steel road plates can be used as a permanent structure or may be moved along as work progresses.  SlipNOT® manufactures innovative solutions for utilities, from crossing plates to highway traffic plates.
