Plywood is glued with phenol glue to produce a flat sheet; or more softwood made of coating layer. tree arranging its fibers perpendicular to each plywood layer reduces shrinkage and increases durability. This cross-grain structure ensures that the final product has high dimensional/dimensional stability, does not warp and does not warp, and is stable/resistant to temperature - humidity changes. Guaranteed to stay.
Plywood Grade 4 - Durable. It is the most basic and durable plywood grade used for building and civil works, formwork and sheet/plate work. It is not sandblasted/ground, there are non-damaging wood defects/faults.
