KRRASS plate rolling machines cover light sheet rolling, medium-duty plate bending, four-roll production, hydraulic variable geometry rolling, and professional profile bending for demanding fabrication work.
Compare KRRASS 3-roll, 4-roll, hydraulic variable geometry, and profile bending machines by plate size, thickness, structure, and production role.
Asymmetrical 3-Roll Plate Rolling Machine
W11F uses an asymmetrical three-roll structure with two rolls on one side and a third roll that moves diagonally. It is a compact choice for smaller workpieces and thinner sheet metal rolling.
Symmetrical Mechanical 3-Roll Plate Bending Machine
W11 uses two symmetrical lower rolls and a vertically moving upper roll. It is a practical mechanical three-roll solution for medium plate thickness, standard cylinder rolling, and general fabrication.
Four-Roll Plate Rolling Machine for Productive Forming
W12 uses a fixed upper roll, vertically moving lower roll, and two side rolls that move upward along linear guideways. The four-roll grip improves control, productivity, and repeatability for thicker and larger plates.
Hydraulic 3-Roll Variable Geometry Plate Roller
W11S builds on the three-roll concept with hydraulic variable geometry. The upper roll moves vertically while the lower rolls move horizontally inward or outward, giving the machine more flexibility for large, thick plates.
Professional Section and Profile Bending Machine
W24S is engineered for bending special profiles instead of flat plate. It supports angle, channel, beam, bar, and other structural profile work with dedicated roll tooling and guide devices.
KRRASS plate rolling machine solutions cover 3-roll, 4-roll, variable geometry, and profile bending needs with stable forming performance.
KRRASS rolling machines support global plate forming projects for tanks, vessels, ductwork, shipbuilding, steel structures, and profiles.
KRRASS rolling machines support tanks, pressure vessels, pipes, cones, shells, ductwork, shipbuilding parts, steel structures, and profile bending.
Plate rolling for aerospace tooling, curved panels, duct sections, and formed structural sheet components.
Heavy-duty rolling machines for shipbuilding plates, hull sections, marine pipes, and cylindrical structures.
Consistent plate and profile rolling for automotive tooling, tanks, guards, and formed production parts.
Reliable rolling for appliance drums, round housings, ventilation parts, and cylindrical sheet metal products.
Plate rolling machines for pressure vessels, steel structures, cones, pipes, ductwork, and construction machinery.
Flexible 3-roll, 4-roll, and profile bending solutions for tanks, shells, job shops, and general fabrication.
Start with the workpiece shape, then match plate thickness, working width, pre-bending need, and production volume to the right roll structure.
Use W24S when the workpiece is an angle, channel, beam, bar, or other profile. For flat plate and sheet metal, choose among W11F, W11, W12, and W11S by thickness, width, minimum rolling diameter, and how often you need accurate pre-bending.

Dedicated section bending machine
W11F is the compact entry choice for smaller and thinner sheets. W11 is the standard mechanical 3-roll machine for medium-duty cylindrical work. W12 adds a fourth roll for better gripping, easier operation, and higher repeat productivity.
W24S is not a flat plate roller. It is built for special profiles such as angle steel, channel steel, beams, bars, and structural sections where dedicated roll tooling and guide rolls matter more than plate working width.
Three-roll machines are practical for general rolling, four-roll machines improve grip and production flow, and variable geometry machines let the lower rolls move inward or outward to adapt the bending span for heavy plates, thin plates, and high-quality edge bending.
Compare the five rolling machine families by structure, workpiece type, capacity role, and selection priority.
