Gatorboard is a lightweight board which is strong and resists bowing. It has a polyfoam core, but the facing material is melamine impregnated to give it a hard surface. Gatorboards are much stronger than ordinary Foamboards and less prone to bowing making them the board of choice for large works, longer term applications and as a premium backing in frames. We supply Gatorboards in 5, 10 and 20 mm. The 10 and 20 mm comes with a black or white edging as a finish.
