Sheet metal beading machines are specialized machines that create reinforced edges, flanges, and ribs on sheets of steel, aluminum, and other metals. They are used by tinsmiths, panel beaters, metalworkers, and artisans who need to prepare sheet metal for joints, structural reinforcements, or aesthetic finishes.
In this guide, we analyze the 8 best professional beading machines available in Italy in 2025, all from the German brand Bernardo, comparing manual and electric models to help you choose the machine best suited to your needs.
Sheet Metal Beading Machine: What It Is and How It Works
A beading machine (also called a beading and flanging machine or flanger) processes sheet metal by passing it between two shaped rollers that rotate in opposite directions. The rollers progressively deform the metal, creating the desired profile: folded edge, reinforcing rib, flange for joining, or decorative profile.
The principle is simple but requires mechanical precision. The shafts supporting the rollers must be perfectly aligned and mounted on quality bearings to ensure:
- Uniformity of the edge along the entire length
- Absence of scratches or marks on the sheet metal
- Repeatability between pieces
- Long-term durability without play or premature wear
Beading machines are divided into two main categories: manual (crank-operated) and electric (motorized). The choice depends on the sheet metal thickness, production volume, and available budget.

How to Choose the Right Flanging Machine
Criterion 1: Maximum Sheet Thickness
The most important parameter is the maximum thickness you need to work with. Bernardo specifications refer to steel with a strength of 400 N/mm²:
- Up to 0.8 mm: any manual flanging machine (SM 180 S, SM 200, SM 250 T, SM 470)
- Up to 1.2 mm: MSM 250 C electric
- Up to 1.6 mm (or 2.0 mm aluminum): MSM 300 C
- Up to 2.5 mm: MSM 400 C
- Up to 4.0 mm: MSM 500 C
Always choose a machine with a capacity higher than your usual thickness. Constantly working at the maximum limit accelerates wear and reduces edge quality.
Criterion 2: Production Volume
For occasional work (less than 2-3 hours a day), manual flanging machines are sufficient and more economical. For regular or continuous production, electric machines eliminate fatigue and ensure uniformity impossible to achieve manually.
Criterion 3: Working Depth
The working depth determines how far you can enter the panel from the edge. For wide sheets or central operations, greater depths are needed:
- 200 mm: standard applications (SM 180 S, SM 200)
- 250-300 mm: increased flexibility (SM 250 T, MSM 250 C, MSM 300 C, MSM 400 C)
- 330 mm: deep processing (MSM 500 C)
- 470 mm: large panels (SM 470)
Criterion 4: Included and Optional Rollers
More rollers included means more profiles can be created without additional purchases:
- 7 pairs: SM 200 (best manual equipment)
- 6 pairs: SM 180 S, SM 470
- 4 pairs: SM 250 T, MSM 250 C, MSM 400 C, MSM 500 C
All Bernardo flanging machines accept optional special rollers for specific profiles (round edges, decorative ribs, special flanging).

Frequently Asked Questions about Sheet Metal Flanging Machines
What is the difference between manual and electric flanging machines?
Manual flanging machines are hand-cranked, cost €286-841, and work sheets up to 0.8 mm. They are ideal for low volumes and do not require electricity. Electric flanging machines have a 400V three-phase motor, work thicknesses up to 4.0 mm, ensure constant speed, and include safety systems. They cost €2,659-5,441 and are designed for continuous professional use.
What sheet metal thickness can I flange?
It depends on the model. Bernardo manual machines work up to 0.8 mm on 400 N/mm² steel. Electric machines start from 1.2 mm (MSM 250 C) and go up to 4.0 mm (MSM 500 C). For aluminum, the capacity increases: the MSM 300 C works up to 2.0 mm. Always work below the maximum limit for optimal results and less wear.
What are the optional special rollers for?
Rollers determine the edge profile. The included ones cover standard flanging and seaming. Optional rollers (€110-180 per pair) allow for special profiles: round edges of different radii, decorative ribs, angled flanging, profiles for gutters. All Bernardo machines accept optional rollers of their respective series.
Which flanging machine for car bodywork?
For restoration and bodywork, we recommend the SM 180 S (€286) or SM 200 (€744). The 200 mm depth covers car panels, the 0.8 mm thickness is sufficient for bodywork sheets, and the 6-7 included rollers allow for the most common edges. The SM 180 S is also transportable for off-workshop interventions.
Is three-phase power needed for electric machines?
Yes, all Bernardo electric flanging machines operate on 400V three-phase power. There are no single-phase versions. If your workshop only has 220V single-phase, consider manual flanging machines or the installation of a three-phase meter.
How long do the rollers last?
With normal use and proper maintenance (periodic lubrication, cleaning after use), Bernardo rollers last for years. Wear depends on the volume of work and the thickness worked. Optional rollers cost €110-180 per pair, so replacement is not particularly expensive.
