Green Board Color
A special function coated steel sheet used for black boards.
A smooth surface with superior writability, erasibility, and anti-wear properties.
USAGE
Green board: The two types of green board include one for chalk made from carbonic acid or sulphuric acid; the other is for anti-powder flying chalk.
White board: Improved writability, erasibility and anti-wear properties overcome problems with whiteboard coating.
Any type of erasable marker may be used.
