Abrasion Resistant Plates – Rock Star 400 / 450 / 500

Premium-grade abrasion-resistant (AR) steel plates, Rock Star 400, 450, and 500 are designed to function remarkably well in settings where durability and high wear resistance are essential. In order to provide exceptional mechanical strength, excellent surface toughness, and prolonged wear life under the most severe situations, these plates are made utilizing sophisticated metallurgical methods. Regardless of your industry—mining, earthmoving, building, recycling, cement, or quarrying—Rock Star AR plates provide the durability and functionality you require to lower maintenance expenses and downtime.
