Description
The W12-20×3000 is a production-grade hydraulic 4 rolling machine designed for accurate cylinders, large radii and cones on 20 mm × 3000 mm mild-steel plates. The 4-roll architecture enables true one-pass pre-bending without turning the plate, minimizing straight edges and setup time while improving repeatability. With NC/CNC options, hardened/crowned rolls and available top/side supports, it suits heavy fabrication, tanks and vessels, shipbuilding and steel-structure projects.
