Metal Bending Rolls

Metal bending rolls, including Piranha and Bertsch plate rollers, are engineered to form steel, stainless steel, and aluminum plate into cylindrical, conical, or curved shapes. Capacity and material thickness vary by model, so it's best to consult Piranha's technical team to match a machine to your specific gauge and alloy requirements.

A 4-roll plate bending machine, like the Bertsch EVO series, uses four rolls instead of three to grip and pre-bend plate edges without repositioning. This design reduces flat spots at the plate ends, improves cycle times, and allows for more autonomous, repeatable bending compared to traditional 3-roll machines.

Yes. Piranha offers an online shop-building and pricing configurator that lets you tailor bending roll specifications to your production needs. Their technical support team also works directly with fabricators to recommend configurations suited to unique bending requirements, plate thicknesses, and production volumes.

Pricing for Piranha and Bertsch plate rollers is available on request. You can use Piranha's online configurator to build a custom machine and receive pricing, or call their sales team directly at 800-338-5471 to discuss your bending roll requirements with a fabrication expert.

Metal bending rolls are widely used in trailer and truck body manufacturing, structural steel fabrication, power and transformer production, and general metal fabrication shops. These machines form plate into curved or cylindrical components used in tanks, enclosures, trailer bodies, and structural assemblies.
