Precision Tolerances

One surface is skidded smooth which allows for flatness and uniformity. Tolerances are +/- 1/16" for thickness and +/- 1/8" for width and +/- 1/8" length fabrication.

ECOSE Technology

Our patented, bio-based binder is a smarter alternative to using phenol formaldehyde. It’s been foundational in our commitment to sustainability.
