Plywood is made by assembling number of veneers in defined pattern to get uniform strength in different directions. Typically the veneers are strong in the direction of grains and hence veneers assembled in different directions provide strength in different directions. The veneers are coated with synthetic resin and then assembled. The assembled mat is hot pressed to form it into a plywood. Smaller factories make plywood using plantation wood primarily due to absense of quality logs. Plywood is made by logs such as imported Gurjan, Silver Oak,Eucalyptus, Popular and other African wood.

A vast number of varieties of plywood exist for different applications - these depend on wood from which they are made.

Softwood plywood is usually made either of spruce, pine, and fir, and is typically used for construction and industrial purposes.

Decorative plywood is usually faced with hardwood, including red oak, birch, maple, lauan (Philippine mahogany) and a large number of other hardwoods.

Plywood for indoor use uses urea-formaldehyde glue that has limited water resistance. Outdoor and marine grade plywood use water resistant phenol-formaldehyde glue to prevent decay and preserve strenght in humid environment.

Other types of plywoods are fire retardant, moisture resistant, marine grade, sign grade, pressure treated, hardwood and softwood plywoods. Each of these products are designed to fill a need in industry. Applications: Quality Furniture, Structural work in interior design, Auto Motive Coach Building, Match-plates in Foundries. Applications: Furniture and structures exposed to heavily fluctuating humidity Cycles, Furniture used in washrooms, bath rooms and kitchens, Match plates in Foundries. Applications: Boat Building, Load and stress Bearing Industrial uses. Applications: Industrial Filters, Panelling and ceiling substrate in Hotels, Hospitals, Theatres, etc. Recommended for all safety conscious people. Applications: Gliders, Small Aircraft manufacture.
They are made from mahogany and/or birch, and use adhesives with increased resistance to heat and humidity. Applications: Industrial Filters, Panelling and ceiling substrate in Hotels, Hospitals, Theatres, etc. Recommended for all safety conscious people.

• High uniform strength Plywood is 45 times stronger along the grain than across the grain. The strength can be made equal in all directions by crossing 2 sheets of plywood.
• Non-splitting qualities:Plywood can easily be nailed or screwed near the edges as splitting does not cause any damage like in other wood.
• Removal of shrinking, swelling and warping: The construction of a plywood panel with the grain direction of adjacent veneers at right angles equalises stress and reduces shrinkage, swelling and warping.
• Availability of relatively large sizes: Plywood can be sold in larger sizes compared to sawn timber which can have long lenghts but the width is narrow.
• Economical and effective utilisation of figured wood: Sheets of plywood can be glued to core of cheaper material can produce a high grade panel. This typically cannot be duplicated with other materials.
• Fabrication of curved surfaces:Curved surfaces and shapes can be readily fabricated in plywood construction, utilising male and female forms, or a single forming a vacuum press or autoclave.
• Reduction of waste: The waste is reduced in plywood from whatever waste happens in sawing. This results in conservation of timber.
• Wood can be sliced and bonded into plywood panels for use in furniture construction. Furniture from timber or other would is heavy and can't ususally have other wood panels.
