Pragati Marine plywood is manufactured from durable face and core veneers, so it performs longer in both humid and wet conditions and resists delaminating and fungal attack. Its construction is such that it can be used in environments where it is exposed to moisture for long periods.
The finished plywood is subjected to proper chemical treatment with Water-Soluble fixed type preservatives under vacuum pressure to ensure protection against wood destroying organism and to make the product insects, borer, termites and fungi free.
