BLOCK BOARD IS:1659

MAESTRO block board is a premium quality board with high resistant properties againse borer and terrnite attacks. All the three components of this block board i.e., Face Veneer, Core Veneer & Wooden battens are well matched. The wooden battens are thoroughly seasoned in scientifically run seasoning kiln plants and then cut with great precision to obtain uniform thickness.

These battens are systematically arranged and utmost care is taken to avoid any extra gap between the battens. Regular tests are conducted to maintain the quality of blockboards as per the standards of IS:1659.

Suggested uses:

Suggested uses: Furniture and partitions, panels, beaded doors, interiors of portable houses, bins, racks. Where panels of higher thickness with greater banding resistance are required.
