No “Armstrong” Processing: The New Standard for 1/8" Aluminum Signs

See the Proof: 1/8" Aluminum Punching in Action

Watch the Porta Press corner rounder shear through .125 aluminum plate with a perfect, clean radius in under two seconds. No strain, no mess.

1. The Power: Punching 1/8" Without the Pull

Most desktop corner rounders are built for thin sign blanks (.040" or .063"). Try to force 100 thou or 1/8" aluminum through those tools, and the result is usually a jammed blade or a strained back. Our station handles the heavy lifting for you.

• Effortless Shearing: Optimized handle geometry and pneumatic power.
• Burr-Free Results: Clean cuts that eliminate secondary grinding time.
• Inclusive Shop Floor: High production speeds maintained by any operator.

2. The Geometry: Why the 3-Inch Radius Matters

For MUTCD compliance and FDOT infrastructure, a standard radius isn't enough. A 3-inch radius is the "Gold Standard" for safety, wind-load resistance, and coating longevity.
