Hardwood Block Board
A blockboard, also known as a lumber core, is an artificial board. In hardwood blockboards, the hardboard veneers are pressed and glued together with thick hardwoods under high pressure. The glue used in hardboards is used in the exteriors. Zander hardwood block boards are in wide use for interior as well as exterior. The hardwood blockboards are used for making bookshelves, benches, heavy top tables, sofas, doors and flush doors with a solid core, wall panels, railways carriages, and bus bodies, among many. The hardwood raw material makes the final board stronger, with a heavier and dense structure.

Zander hardwood block boards feature stiffness and stability across their length. Due to this reason, long panels of blockboard are used to craft doors. The boards are easy to handle and cut. The solid and durable water-resistant blockboards are suitable for outdoor uses, such as flooring and decking.
