Green Chalkboard Writing Surface
The classroom standard, batch after batch.
A matte green surface formulated for chalk rather than markers — low glare under classroom lighting, even chalk take-off, and a tone held within a tight band so a replacement panel matches the board already on the wall.

Why buyers specify it
Why schools keep ordering green.
01
Low glare by design
The matte finish scatters light instead of reflecting it, so the board reads clearly from the back row under ordinary classroom tubes.
02
Chalk behaves on it
Surface micro-texture takes chalk evenly and releases it cleanly — no slick patches, no squeaking, no ghost images after wiping.
03
Tone held in a tight band
Green is measured per batch and logged, so panels from different orders sit side by side without a visible seam.
04
Frames like any other panel
Same steel core and gauge range as our whiteboard surfaces — your cutting and framing line does not change.
