Rolling is a universal term applied to processing that takes a variety of products and passes them through a series of rolls to produce a specified radius. Plate rolling is performed on a variety of rolling machines with three long rollers arranged either in pyramid or pinch style. Pressure is gradually increased on the material as it passes back and forth between the rotating rolls until the desired arc is permanently set.
Angles, structurals, bars, tubing, and pipe are essentially rolled the same as plate, except the rolls are short, heavy, and supported only on one end. Angles can be rolled leg in or leg out. Channels can be rolled flange in or flange out.
Many of O'Neal's materials can be furnished rolled to complete circular shapes (360°), or to any degree of a circle. For example, sheet and plate can be rolled into cylinders. Bars, structurals, tubing, and pipe can be rolled into rings. A ring segment can be either part of a circle or with straight segments at one or both ends to allow for further processing and forming.
The majority of rolled rings are A-36 structurals. However, we can also roll material such as alloy bars, stainless, aluminum, and nickel alloy plus various grades of tubing and pipe.
O'Neal can roll plate up to 1" in thickness and 10' in length. Rolling capabilities for angles, structurals, bars, tubing, pipe, and other shapes are virtually unlimited.
