  • Description

    The Malco ER3 3-Station Metal Edge Roller delivers clean, uniform bends along the full length of metal roofing panels. Designed for professional field forming, the ER3 quickly adjusts to create bends from 5/8″ to 4″ deep in 29–22 gauge steel.

    Its exclusive 3-station roller design distributes pressure evenly across the material, producing consistent bends all the way to the panel ends. A precision English/Metric depth gauge on the center station ensures accurate, repeatable settings across all three roller stations.

    The independently adjustable center roller also allows mild curved bending by retracting the outer stations, giving roofing professionals greater flexibility in the field.

    Built with hardened rollers and heavy-duty components, the ER3 is designed for long service life and daily jobsite use.

Malco ER3 3-Station Metal Edge Roller – Adjustable 5/8″–4″ Bend Depth

Frequently Asked Questions

What makes the ER3 different from 2-station panel benders?

The ER3 uses a true 3-station roller design, meaning three roller assemblies contact the panel during bending. This distributes pressure more evenly across the material and produces a highly uniform bend along the entire length of straight panels.

Compared to 2-station tools, the ER3 offers:

  • More consistent bend depth
  • Better tracking over long straight runs
  • Improved stability on wider panels

It is especially effective when uniformity across long panels is critical.

What materials and gauges can the ER3 bend?

The ER3 is rated for 22–29 gauge steel (approximately .030″–.014″ thick).

This includes common roofing materials such as:

  • 29–26 gauge residential standing seam
  • 24–22 gauge commercial roofing panels
  • Trim and flashing stock within the rated thickness range

Always verify material thickness before bending to ensure it falls within rated capacity.

What bend depths can the ER3 make?

The ER3 is adjustable from 5/8″ to 4″ (15.9–102 mm) in bend depth.

This allows you to:

  • Form shallow trim edges
  • Create deeper custom flashings
  • Adjust quickly between applications without changing tools

The precision English/Metric gauge ensures consistent depth alignment across all three roller stations.

Can the ER3 bend curves?

Yes.

The center roller station can be independently adjusted while the outer stations are retracted and locked. This allows the tool to make mild curved bends.

For best results:

  • Use lighter pressure
  • Make multiple passes
  • Avoid attempting full 90° bends on tight curves

The ER3 performs best on curves with a radius of approximately 17 feet or larger.

Do the rollers need to be replaced?

No. The ER3 features hardened rollers designed to last the life of the tool under normal professional use. Rollers are not intended to be replaced.
