TC Industries Mill Products Division provides a variety of straightening services.
Steel often has to be mechanically straightened after Q&T due to the distortion that takes place during the hardening process. Rounds, structural shapes, and flat bar products are straightened using hydraulic presses or rotary straightening. If required by the specification or customer, subsequent stress relieving processing may be performed.
In the course of most of our heat treat cycles, the material undergoes some distortion. We have straightening capabilities for nearly any material size and shape that we can heat treat. The division is equipped with three rotary straighteners for round bars. We also have two roller levelers for flat material. The division has six horizontal hydraulic presses for straightening heavier flats and squares. These are also used to camber-straighten flat bars. We have one 500 Ton horizontal press for use on heavier rounds.
Bars of special straightness are furnished within a variation from a straight line of not more than 1/8" in any five feet, but may not exceed 1/8" times number of feet of length divided by five.
Please note that we are unable to straighten twisted bars. Round bars from .4" to 1" in diameter are limited to 25 feet maximum length.
