The W12-12×2500 is a production-grade metal rolling machine engineered to form accurate cylinders, large radii, and cones from 12 mm × 2500 mm plates (mild steel). Its hydraulic four-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 tank & vessel fabrication, shipbuilding, steel construction, and general fabrication.
