MRM 2050 Series • Motorised Plate Rolls
Please contact for prices
The MRM 2050 Series is a range of motorised initial-pinch plate rolls designed for bending mild-steel sheet up to 2050mm wide. Four models cover capacities from 4.0mm to 8.0mm and use roll diameters from 130mm to 220mm, allowing the range to suit a broad selection of fabrication work.
The asymmetrical three-roll arrangement supports efficient rolling and pre-bending. Upper and lower rolls are directly driven through a hardened gear system to provide positive material feed, while the motorised rear roll with mm counter allows controlled adjustment. The machines include polished alloy-steel rolls, a manual drop-end top roll for removal of completed cylinders, a mobile three-position foot pedal with emergency stop, conical bending device and heavy-duty brake motor.
The MRM 2050 Series comprises heavy-duty motorised three-roll plate rolls with a 2050mm bending length and mild-steel capacities from 4.0mm to 8.0mm, depending on model. The range combines dual driven rolls, motorised rear-roll adjustment and a manual drop-end top roll for general fabrication, sheet-metal rolling, HVAC ducting and curved components.

How to Choose a Plate Roll
Choose a plate roll by considering the material, maximum sheet thickness and bending length first. Then check the minimum bending diameter required, together with whether the work is occasional, regular or production use. Capacity figures should always be assessed against the actual material grade and whether the application requires rolling or pre-bending.
1. Material and Thickness
Select a machine based on the thickest material you need to roll, not the material you handle most often. Mild-steel capacity is the normal reference point; stainless steel generally requires a larger machine, while aluminium may allow a higher capacity. For consistent production work, allow a sensible margin rather than operating continually at the machine’s stated maximum.
2. Bending Length
The bending length must accommodate the widest sheet or component you need to form. Allow clearance beyond the finished part width where practical, particularly if workpieces need to be positioned accurately or repeatedly.
3. Minimum Bending Diameter
The minimum bending diameter is determined mainly by roll diameter and machine geometry. Smaller rolls can produce tighter diameters, while larger rolls are normally better suited to heavier material. Confirm the required finished diameter before selecting a machine.
4. Pre-Bending Requirement
Pre-bending reduces the flat section left at the leading and trailing edges of a rolled sheet. If you need cylinders, cones or curved components with minimal flat ends, choose a machine with suitable pre-bending capacity rather than relying only on its maximum rolling capacity.
5. Manual or Motorised Operation
Manual slip rolls suit lighter-duty work, thinner material and occasional use. Motorised plate rolls provide more controlled, repeatable rolling for heavier sheet, wider material and regular fabrication. Motorised rear-roll adjustment is particularly useful where settings need to be repeated between parts.
6. Finished Part and Production Requirement
Consider the full application: material type, sheet thickness, bending length, finished diameter, quantity of parts and required edge quality. This gives a better basis for machine selection than choosing only by nominal capacity.
