• C Finish: caramelized with a proprietary smoke-free coating for enhanced tensile strength and handling properties.
• R Finish: caramelized with a proprietary coating for enhanced abrasion resistance.
• S Finish: caramelized with a proprietary coating of silicone rubber.
• H Finish: before the C Finish, a proprietary chemical treatment is applied to increase
continuous working temperature to 1065°C (>1950°F) while reducing the area shrinkage
