Roller materials: Metal. The ideal material for a roller is stainless steel; it is hard, durable, and virtually maintenance-free. Unfortunately, it is much more expensive than mild steel and harder to work with. Stainless steel can cost up to four times as much as other materials, and the labor will be 50% more expensive at any machine shop.
