Plywood is available at local retail stores and specialty wholesalers. with most offering a wide selection.


       Plywood has been one of the most recognized. and trusted wood building products for decades. Manufactured from thin sheets of cross-laminated veneer and bonded under heat. and pressure with strong adhesives, plywood panels have superior dimensional stability. and an excellent strength-to-weight ratio. and are resistant to impacts, chemicals, and changes in environmental temperature and humidity.


      Plywood manufactured by APA member mills is . available in a wide variety of appearance grades. ranging from smooth. natural surfaces suitable for finish work to more cheap grades used for sheathing. With more than a dozen common thicknesses and over twenty different grades. plywood is well-suited to a multitude of demanding applications.

plywood size thickness


       The usual length and width specifications are 1220 x 2440 mm. while the thickness specifications are generally 3, 5, 9, 12, 15, 18 mm.  The main tree species are beech, camphor, willow, poplar, eucalyptus and so on.


 What are different types of plywood? 


      Plywood is a kind of three or more layers of laminated material. which made up of wood segments cut into veneers or planned into thin wood, then bonded with adhesives. Odd layers of veneers are

usually used, and the fibers of adjacent layers of veneers bonded to each other.


      Softwood is a type of plywood. that manufacturers make using softwoods, like pine, redwood, or cedar. Although the name implies that these woods aren’t as strong as others. you might surprised to know that construction workers. use softwoods for exterior frame sheathing, roof sheathing. and sub-flooring.


      Softwood plywood can also create things like sheds. temporary flooring, doghouses, shelving, and more.


      Hardwood plywood has between three and seven layers. and uses hardwoods, like birch, maple, oak, and walnut. Manufacturers glue the layers of wood at right angles to. one another to create an strong finish.


      Hardwoods are best for things like furniture, packing cases, sporting equipment, musical instruments. and other intricate projects that need strong frames.

What is plywood used for?


      plywood is suitable for a variety of end uses. including subflooring, single-layer flooring, wall and roof sheathing. sheathing ceiling/deck, structural insulated panels. marine applications, siding, webs of wood I-joists, concrete forming, pallets. industrial containers, mezzanine decks, and furniture.


   plywood application has many , so you can use whichever type you deem fit based on the project you’re building. But, to make shop plywood online easier, most suppliers. or lumber stores will break down their plywood in basic building materials categories.


      structural plywood or exterior plywood designed. for permanent use in building structures like beams, subfloors. bracing for walls or roofs. and in any other instance where strength and stability are vital. Structural plywood is often quite thick. made of softwood species and without an attractive finish. The majority of veneer core structural plywood is moisture-resistant.


      Exterior plywood is going to be strong, but most. it’s designed for water-resistance and weather exposure. Adhesives used in Exterior plywood withstand water. and harsh sunlight for longer without degradation. But, Exterior plywood that will exposed to the elements. engineered wood exterior plywood will still need a surface treatment (e.g. waterproof sealant) . as it designed to covered with siding, flooring, roofing, etc.


      Interior (decorative) plywood is usually chosen for its looks rather than its strength. You’ll find Interior plywood ideal for household home improvement projects like wall paneling, ceilings. and ceiling treatments (e.g. coffered ceilings) cabinets and furniture. Interior plywood should not used for structures nor should interior plywood used outdoors.


       If you’re looking for beautiful look. consider skipping softwoods and selecting an interior, hardwood product instead. Hardwood plywood is a budget-friendly way of getting a stunning real wood finish. without the price tag of solid wood.


exterior plywood usage


      plywood sheets is one of the common furniture materials. It is one of the three major wood-based panels. It can also  used for plane, ships, trains, automobiles, buildings and packing boxes. A group of veneers are usually bonded to each other in the direction of the adjacent wood grain. Usually, the surface and inner veneers arranged on both sides of the central layer or the core. 


       Slab made of glued veneer interlaced. and in the direction of wood grain pressed under heating or non-heating conditions. The number of layers is usually odd, and a few even. The difference of physical and mechanical properties. between vertical and horizontal directions is small. The commonly used plywood types are three plywood and five plywood. Plywood can improve wood use rate, which is a main way to save wood.
