SOFTWOOD PLYWOOD USES
Softwood Plywood is used mainly in the construction industry for structural purposes. There are many grades, sizes and thicknesses of softwood plywood depending how they are to be used however in the highest of grades they are sometimes used for decorative purposes such as furniture and cabinet making. Most softwood plywood is made with moisture resistant glue (such as phenol resin adhesive#1) and are Exterior Grade panels.
Softwood plywood can be handled with ordinary woodworking tools and basic skills. When hand sawing or cutting on a table saw, support the panels firmly with the best face up. Cut with the best side down when using a portable power saw. Do not force-feed the panel into the tool or the tool into the panel too quickly because this will increase the roughness of the cut and may induce splintering-out on the exit side. Proper backup of the material also can reduce splintering.
