Engineering highlights

Crafted from high tensile spring steel, each bar is produced as a one-piece item for maximum integrity. The material is cold worked for surface finish and stress resistance, then heat tempered for long-term durability. The result is consistent roll stiffness and long service life, even with hard use in demanding conditions.
