PLYWOOD is a versatile building material that can be used in decks, flooring, roofing and walls. Plywood is used in many interior and exterior applications and is even found in boat construction. It is durable material that provides a excellent foundation for building.
ADVANTAGES OF PLYWOOD
Plywood is constructed of layers of wood glued together at right angles, which is what gives it its strength. This layering make the plants resistant to warping, cracking and twisting, making it ideal for use in construction.
In addition to its strength, plywood is less expensive than similar boards made of full wood species, which makes it ideal as a construction planking material.
A typical plywood panel has face veneers of a higher grade than the core veneers. The principal function of the core layers is to increase the separation between the outer layers where the bending stresses are highest, thus increasing the panel's resistance to bending. As a result, thicker panels can span greater distances under the same loads. In bending, the maximum stress occurs in the outermost layers, one in tension, the other in compression. Bending stress decreases from the maximum at the face layers to nearly zero at the central layer. Shear stress, by contrast, is higher in the center of the panel, and zero at the outer fibers.
GRADE OF PLYWOOD
Grading rules differ according to the country of origin. Most popular standard is the British Standard (BS) and American Standard (ASTM).
1. A-----------Face and back veneers practically free from all defects.
2. A/B--------Face veneers practically free from all defects. Reverse veneers with only a few small knots or discolorations.
3. A/BB------Face as A but reverse side permitting jointed veneers, large knots, plugs, etc.
4. B-----------Both side veneers with only a few small knots or discolorations.
5. B/BB------Face veneers with only a few small knots or discolorations. Reverse side permitting jointed veneers, large knots, plugs, etc.
6. BB---------Both sides permitting jointed veneers, large knots, plugs, etc.
7. WG--------Guaranteed well glued only. All broken knots plugged.
8. X------------Knots, knotholes, cracks, and all other defects permitted.
9. BB/CC----Face as BB, back as CC. BB as very little knots of less than 1/4 inches, slight discoloration, no decay, split and wormholes mended skillfully, matched colors, no blister, no wrinkle. Most popular choice for most applications.
