Off-axis bending is also called conical rolling and is specified by citing a major and a minor diameter along with the height and degree of arc of the curved steel. In construction applications, off-axis bends are commonly used on roofs and domes and can be formed from many shapes including angle, bar, beam, channel, tube, sheet and plate. Conical steel bending is also commonly used in industrial equipment such as funnels, transitions, and stacks.
With its enormous capacity, Chicago Metal Rolled Products can perform the steel bending of some of the most challenging off-axis assignments. In most cases with our curved steel we can match the degree off-axis that you specify. "Hard-way, easy-way and every way in between!"®
Additional operations can be performed on off-axis curved steel including beveling, welding, punching, drilling, and cutting.
A spectacular application of 45-degree-off-axis bending of 5" square tubing can be seen in the barrel vault skylight at the Kimmel Center for the Performing Arts in Philadelphia. Chicago Metal rolled 300 tons of steel to radius tolerances within 1/16". For the Milwaukee School of Engineering the company rolled heavy tubing off axis and slightly helical for their Student Center. And at the Little Village High School in Chicago, we rolled 40 pieces of 8 x 6 x 0.375 rectangular tubing the easy way 10.9 degrees off axis to form a tapered tower.
