Description
The W12-40×2500 is a heavy-duty industry plate rolling machine engineered for precise cylinders, large radii and cones on 40 mm × 2500 mm mild-steel plates. Its hydraulic four-roll architecture enables true one-pass pre-bending without turning the plate, minimizing straight edges and setup time while delivering repeatable accuracy. With NC/CNC options, hardened/crowned rolls, and available top/side supports, it is built for tank & vessel producers, shipbuilding and steel-structure fabrication lines.
