These are made out of the excellent quality of Plantation Timbers. Logs are quarter swan into Planks using the SDR method, which is chemically treated and well seasoned before converting into battens in multiple ripsaws. Battens are sandwiched between two glued mechanically dried veneers and are pressed in the hot press under accurate temperature and pressure. Quarter sawing of logs and proper seasoning of planks make it dimensionally stable and treatment of planks, poisoning of glue line and preservative treatment of finished block board make caliber plywood durable and safe against borers.
