3mm hardboard sheets in standard 2440 x 1220mm (8 x 4) dimensions. Made from dense, compressed wood fibres, 3mm hardboard is a strong, cost-effective option for a variety of jobs. Being on the thinner end for hardboard, these sheets are flexible enough to bend slightly when working, while still being durable. They have a regular dual-surface finish, with a smooth side for finishing and a textured reverse for grip and adhesion. Common uses include floor underlay, wall linings, and backing boards for furniture.
