Frameless OUTDOOR Chalkboard Panels in over 100 standard sizes. Nominal 1/8" thick.
There's nothing like them on the market.
The chalkboard surface is the highest quality porcelain on steel. The panel construction is composed entirely of non-porous materials to give the board extended outdoor life - free from excessive warping and moisture absorption that you would experience when exposing a standard chalkboard to the elements.
- Recommended for do-it-yourself framing.
