Heavy-Duty W12-4X2000 Hydraulic Rolling Machine for Metal Sheets

The biggest advantage is double prebending in one pass. With a 4roller machine, you can prebending both ends of the plate without turning it. With a 3roller machine, you either need to prebending separately or turn the plate to prebending the other end. Saves time, labor, and ensures no remaining straight edge.

Almost zero The 4 roll design allows the plate to be fully pre bent before rolling so the remaining straight edge is minimal to none This is ideal for applications requiring high roundness such as pressure vessels and shipbuilding
