PLATE ROLLING

Plate Rolling is the typical method of curving plate (i.e. sheet of material) into round / cylindrical or conical shapes. This method of rolling is similar to the pyramid rolling method where individual "shafts / rolls" turn independently to form the sheet of material to desired radii. Capacity is defined by thickness of material and overall width of material. A section of plate is placed in a machine and curved between three or four rolls. Bending occurs when the distance between these rolls is manipulated before each successive pass. The diameter that a plate roll can roll a piece of plate will be limited to the roller diameter in the plate roll (i.e. one can’t roll plate to a diameter tighter then the plate roller die itself).

Small: This machine can roll up to 3/8" thick x 6 ft wide A36 material. The tightest we can bend is 8.66" inside diameter on ¼" thick x 2 ft wide A36 material.

Medium: ¾" thick x 10 ft wide A36 material. On this machine we can roll down to a 14¾" diameter.

Large: 2½" thick x 10 ft wide A36 material. The largest diameter we can roll off this machine is up to a 12 ft diameter and we are limited to 20,000# sheets of material (which is our crane capacity). The opening between rolls is 4¾", which is the limit to thickness that can fit in this machine.
