's Skega Poly-Met™ mill linings combine the most desirable properties of rubber and steel to maximum advantage. This combination allows the use of more wear-resistant alloys of iron and steel than can be used in a conventional metallic lining, as the rubber substantially dampens the impact forces and also results in a lower lining weight.
