Each cover is built standard with 22-gauge steel, which is folded at the edges to nearly double the strength at this crucial point of stress. The corrugated design also benefits installation and maintenance efforts, removing a requirement for additional supports. That means on their own the covers are self-supporting. Also, installation is not dependent on the location of an idler frame. Instead, owners can attach the covers with self-tapping screws at any point along the length of a conveyor’s structure. They are available in standard sizes up to 60-inches wide, in lengths of 41.88-inches and in styles of full, half and three-quarter coverage.
