The largest sizes we can typically cut with saw cutting equipment like horizontal band saws is 18.75" diameter or 18.75" x 26.5" rectangle. It is possible to cut diameters up to 24" provided we spin the steel during the cut to reach the complete width. It is important to note that if the round steel needs to be spun during saw cutting, the tolerance would need to be a minimum of +/- 1/8".
