birch trees are deciduous outdoor trees that grow in temperate climates. the white birch, the most distinctive of the birches, is easily recognised by its white, paper-like bark. birch wood is widely used for various purposes because of its easy availability and low price, relative to other species of outdoor.
yellow birch on the other hand, tends to be a larger tree and exhibits a more consistent golden brown colour, with little creamy white sap wood. often yellow birch shows a nice curl pattern. in commercial operations, unlike maple,it is rarely sorted for colour.

plywood categories: wood and natural products; wood. material notes: plywood is made of several thin layers, or 'plies' that are laminated together. the layer structure leads to more uniform properties than solid wood, since the effects of grain anisotropy are minimized.

properties of wood and structural wood products 3.1 introduction wood differs from other construction materials because it is produced in a living tree. as a result, wood possesses material properties that may be significantly different from other materials normally encountered in structural design.
birch plywood from the best material. metsä wood's birch plywood products are produced of high-quality finnish birch. birch plywood is characterized by excellent strength and stiffness properties, and therefore it performs very well in applications demanding high strength and rigidity.

the properties of plywood include increased stability, surface dimensional stability, high-impact resistance, chemical resistance and a high strength-to-weight ratio. plywood is made from layers of wood pressed together and bonded with an adhesive.
because the properties of wood may vary greatly depending on different factors, it is advisable to sort it according to its purpose. sorting can distinguish two main examining criteria, which are the appearance and strength-technical properties of the wood. in wood quality and strength sorting, about 90% of quality criteria are related to its
sustainability: this wood species is not listed in the cites appendices or on the iucn red list of threatened species. common uses: plywood, boxes, crates, turned objects, interior trim, and other small specialty wood items. comments: birch is one of the most widely used woods for veneer and plywood worldwide. besides regular sheets of plywood
