Quality Certifications

Welcome to Shree Gopal UdyogSGU


Veneers from high quality logs are mechanically dried and they undergo stress relieving process, which are assembled insuch a way to from a balanced construction . High quality fortified synthetic resins are used for gluing the veneers. Glue line is poisoned by special formulations of chemicals to make Caliber Plywood safe against borers. It is hot pressed under proper temperature and more than 16 Kg/cm specific pressure. Conditioning is done after pressing, followed by preservative treatment.

Partition and paneling, ceilings in public rooms and corridors, floor underlayment, computer rooms furniture, bus bodies, railway coaches, milk booths, sign boards, insert in panel doors, storage racks.

flush doors

These are made from high Density Farm Timbers, which are chemically treated and well sesasoned. Battens are edge glued to make these doors durable and dimensionally treated and well seasoned. Battens are edge gludeto make these doors durable and dimensionally stable. Special formulations of chemicals are used to poison the glue line against borers and fungus. External preservative treatment is given to make these doors perfectly resistant to all the Micro Organisms.Caliber Flush doors are available in all sizes and thickness. Flush doors are laminated with decorative veneers are per customers' requirements.

Door in homes and offices.

Block Boards

These are made out of excellent quality of Plantation Timbers. logs are quarter sawn into Planks using SDR method, which are chemically treated and well seasoned before converting into battens in a multiple ripsaw. Battens are sandwiched between two glued mechanically dried veneers and are pressed in 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.
