Process and device for substrate with increased slip resistance

Abstract

Disclosed is a process and apparatus for preparing a substrate having a high coefficient of friction on a surface, and the high friction substrate. A pre-process of sanding can be used, followed by thermal wire coating of the sanded surface. The surface can have a static and dynamic coefficient of friction greater than or equal to than 0.85.
