Extremely uniform resistance In the longitudinal direction, this type of wood is 25-45 times more resistant than in the transversal one. Criss-crossing adjacent sheets tend to make resistance equal in all directions.
A material that does not contract, swell and warp Solid wood shows significant changes in the transverse direction to grains, but contraction or swelling on the longitudinal plane are usually limited. A well-balanced manufacturing of a plywood panel with the direction of the grains of adjacent veneers at a right angle tends to balance tension, reducing shrinkages, swellings and deformations.
Anti-tear properties Solid wood breaks easily along the grains. Thanks to its criss-crossed layers, plywood can be nailed or screwed near the edges without danger of breaking.
Availability of relatively large sizes It is possible to obtain sawn wood with a considerable length, but with a relatively limited width. Panguaneta plywood can be sold in sizes up to 3120 x 2120 mm.
Thick woods can be cut into veneers and glued in plywood panels To be used to manufacture pieces of furniture that would be too heavy if built by using solid wood.
Easy construction of curved surfaces The current trend of modern architectural design is to create curved surfaces. With plywood, the desired shapes can be obtained quickly, by using male and female shapes or a single piece forming a vacuum press or an autoclave.
One of the key features of plywood production is that it allows the conservation of wood without the residues of sawing (such as sawdust). The discarded part is limited to the small central part that remains after veneer cutting, the veneers lost by turning the trunk and the defects removed such as knots and cracks.
Plywood panels are to be preferred to others because they use lower quantities of glue and guarantee higher performances.
Resistance being equal, plywood structural works are lighter than those in solid or lamellar wood and, therefore, require a more limited use of material.
