Veneers from high quality logs are mechanically dried and they undergo strees relieving process,which are assemebled in such 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 caaliber plywood safe against borers.It is hot pressed under proper temperature and more than 16 kg/cm specific pressure.followed by preservative treatment.
Partition and paneliing,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.
