Engineered wood is a new all-wood decorative material with superior performance, which is made of ordinary wood (fast-growing wood) as raw material and is produced by various modified physical and chemical treatment of ordinary wood and fast-growing wood using the principle of bionics. Compared with natural materials, almost no bending, no cracking, no distortion. Its density can be artificially controlled, the product stability is good, in the processing process, it does not exist the waste and value loss of natural wood processing, can increase the comprehensive utilization rate of wood to more than 86%.
