Block Board [IS:1659:2004]

Magnus block boards are made in moisture resistant & boiling water resistant grade. The wooden battens are seasoned in scientifically run seasoning kiln plants and then get plain with the four sider precision plainer to obtain the uniform thickness of battens.

These battens are systematically arranged and care is taken to avoid any gap between the battens. Regular test are conducted to maintain the quality of block boards as per relevant standards.

Application: Furniture and partition, panels, beaded doors, interiors of portable houses, bins and racks.

Size (In feet): 6×3, 7×3, 8×3, 6×4, 7×4, 8×4, 7×5, 8×5

Thickness: 19mm
