Blockboard (MR & BWR Grade)

Sonear Block boards are made of extra thick Premium Grade veneers of Imported Pine cut from Central beam and are Core-composed. They are fabricated from extra thick circular pieces of imported hardwood and long core veneers and bonded with the best quality Resin, pertaining to the desired grade, under high temperature and pressure. Utmost care is taken to ensure uniformity so as to eliminate gaps, overlapping or corrugation which prevents the chances of the board disintegrating when cut. Sonear Block boards provide exceptional strength and durability to wall cabinets, cupboards, wardrobe and furniture with additional grip for screws and nails.
