E.grandis plywood had better mechanical properties than poplar plywood, and its properties were comparable to those of beech plywood; however, E.grandis is very fast-growing tree species, whereas beech is a slow-growing species. They are widely employed in structural, exterior, and interior works where they produce outstanding results. RESEARCH ON MECHANICAL PROPERTIES OF BIRCH PLYWOOD WITH SPECIAL VENEER LAY-UP SCHEMES Plywood is a wood-based panel material laminated of veneers where the grain di- rection is perpendicular in adjacent layers. The layer structure leads to more uniform properties than solid wood, since the effects of grain anisotropy are minimized. Metsä Wood's Birch is made of cross-bonded 1.4 mm thick birch veneers. We carry Handprint, Columbia Forest Products, Swaner Hardwood and more. ers, sellers, and users of plywood products as well as other concerned parties. Structural. Key words: plywood, modulus of elasticity, tension, bending, shear. Birch plywood is ultimate in Plywood having excellent physical and mechanical properties.

Why to develop wood-based panel industry?Wood-based panel is made of wood or other plant fibers as raw materials, processed and separated into various unit materials through a special process, and then pressed under certain conditions with or without adhesive.The reason:1) Improved wood properties: the use […] Many of the questions that arise with wood-based compos-ites have to do with their mechanical properties, especially how properties of one type of material compare with those of clear wood and other wood products. Birch has a white sapwood and light reddish brown heartwood. Birch, basswood, or maple is also acceptable as a core material. Nevertheless, only limited research has been conducted to verify the difference between the two methods. 7). This core material is usually poplar. Birch plywood is classified as one of the most popular types of plywood due to its superior mechanical properties and aesthetic appearance. Wood varies wildly. Full plywood range including prefinished architectural panels. The use of plywood can be extended if there is a possibility to use special lay-up schemes designed to improve mechanical properties which depend on the grain direction in the outer plies. Cross-graining (thin plies glued at the right angle with each other based on their pattern of grain) allows the plywood sheets to resist splitting and provides uniform strength with increased stability. Suitable for high quality paint, stain or lacquer finish where the end product is intended to be open to display. Baltic birch's core is unlike traditional plywood you may be used to seeing: the layers of inner plies are about 1 mm-thick solid birch veneer, cross-banded, and laminated with strong adhesive.
