Formply is made of a high-density overlay (HDO) of phenolic resin impregnated paper bonded to plywood. Formply is ideal for concrete formwork. The overlay helps to protect the hardwood face veneer as well as providing a sound surface for the poured concrete, ensuring it holds a structural rating.

The Non-structural Formply is purely for aesthetics, commonly used in cabinetry commercially as well as residentially. It is distinguished from the structural sheets by a green coloured edging.
