Roll Bending
Sheet metal roll bending and plate forming (plate rolling) with 4-roller DAVI MCA in Thessaloniki. Sheet metal forming into cylindrical, conical and elliptical shapes — steel, stainless steel, aluminium. Metal roll bending up to 12mm thickness, 2200mm width, minimum radius Ø200mm.
Sheet Metal Roll Bending
with the 4-Roller DAVI
Sheet metal roll bending (plate rolling) is the process of cold bending of plates through rollers, so that the flat metal sheet acquires curvature — cylindrical, conical or elliptical. It is one of the fundamental methods of sheet metal forming in the metal industry. At Axinar in Thessaloniki we perform metal roll bending with the 4-roller DAVI MCA — a machine with Servo-Tronic CNC technology that ensures a uniform bending radius with no flat spots along the entire length of the plate.
Unlike conventional 3-roller machines, the 4-roller rolls both ends of the plate without the need to flip or re-roll — this means zero flat spots, greater accuracy and faster production time. Servo-Tronic technology CNC-controls the position of each roller independently, achieving conical part rolling and elliptical shape rolling with an accuracy that is not achievable in any 3-roller vs 4-roller comparison.
Applications of sheet metal roll bending include: roll bending for tanks, roll bending for silos, roll bending for chimneys, roll bending for ductwork, large-diameter piping, cones, machine jackets, curved canopies, cylindrical enclosures and metal structures with curved surfaces. We perform steel roll bending, stainless steel roll bending (inox) and aluminium roll bending — custom roll bending in any radius and shape. See our metal structures.
The cost of roll bending depends on factors such as: material (steel, stainless steel, aluminium), plate thickness and width, bending radius, shape type (cylindrical, conical, elliptical), part quantity and any need for seam welding after roll bending. The roll bending price varies accordingly — request a free quote by sending a drawing or sketch.
4-Roller — Zero Flat Spots
The 4-roller DAVI MCA bends both ends without flipping — zero flat spots, uniform curvature across the entire plate.
Roll Bending — Servo-Tronic CNC
Servo-Tronic technology CNC-controls each roller independently, achieving precise bending radius on cylindrical, conical and elliptical shapes.
Max Rolling Thickness 12mm
Sheet metal roll bending up to 12mm thick and 2200mm wide. Minimum rolling radius Ø200mm — ideal for tanks, silos and chimneys.
4-Roller Plate Roll Bending Machine
DAVI — Italian Roll Bending Precision
The DAVI MCA is one of the top 4-roller plate rolling machines in the world. Italian DAVI manufacturing, combined with Promau technology, guarantees reliability and accuracy in every roll bending job.
Conical & Elliptical Shapes
Thanks to the independent motion of each roller, the DAVI MCA performs conical part rolling (tapered rolling) and elliptical shape rolling (oval rolling) with precision — ideal for cones, jackets and transition parts.
No Flat Spots
Unlike 3-roller machines, the 4-roller DAVI rolls the plate ends fully. This eliminates flat spots — critical for tanks, silos and applications that require perfect seam welding.
Why Sheet Metal Roll Bending at Axinar
Bending radius accuracy
The Servo-Tronic CNC technology of the DAVI MCA ensures a uniform bending radius along the entire length of the plate. Sheet metal roll bending with precision — no deviations, no flat spots.
Conical & elliptical roll bending
The 4-roller DAVI performs conical part rolling (cones, transitions), elliptical shape rolling (oval) and cylindrical enclosures — full geometric freedom in metal roll bending.
Steel, Inox & aluminium roll bending
We perform steel roll bending (S235, S355), stainless steel roll bending (304, 316), aluminium roll bending, galvanised and cast iron. Cold bending of every metal sheet — the DAVI MCA rolls them all.
Tanks, silos, chimneys, ductwork
Roll bending for tanks, storage silos, chimneys, ductwork, large-diameter piping, cylindrical machine enclosures — custom roll bending for every industrial application.
4-Roller vs 3-Roller — Zero Flat Spots
The 4-roller bends both ends of the plate simultaneously — unlike the 3-roller which leaves flat spots. This eliminates flat spots, reduces setup time and simplifies seam welding.
