These materials are chosen for their strength, durability, and ability to withstand the high forces and stresses generated during the roll forming process. Steel frames are often reinforced with additional supports to minimize vibrations and maintain alignment of the forming rollers, which is essential for producing consistent and precise metal profiles.

The choice of material also depends on the machine's size and the type of metal it will be forming. Heavier frames are used for larger, industrial machines to ensure stability and long-term durability.
