The present work discusses the possibility of coating steel sheets by polyurethane reinforced by copper, steel and nickel chrome wires. The abrasion resistance of polyurethane coatings of steel sheets has been investigated. The tested polyurethane composite coatings are proposed to decrease erosion wear of buildings and defeat sand erosion during dusty storms. Experiments have been carried out using sand blast test rig. Based on the experimental results, it was found that erosion wear decreases with increasing wire diameter, where the wire strengthens the eroded area. Besides, minimum value of wear of polyurethane coating reinforced by copper wires is observed when the substrate was coated by two layers. Ni Cr wires shows minimum wear when the substrate i coated by three layers.
