Methods for producing structural materials from lumber are provided. The methods use an oxygen pre-treatment or a carbonate pre-treatment followed by densification via thermal compression to produce structural materials with strong mechanical properties. The pre-treatments are able to partially delignify the lumber without substantially adversely affecting the mechanical properties of the subsequently densified wood.

The invention provides the method for producing fire retardant, decay and moisture resistant lumber, and production line for its implementation, achieved by combining a treatment chamber and other technological components in one production line, resulting in possibility of carrying out a multi-stage lumber treatment within the same treatment chamber, by using water-insoluble natural mineral raw materials to impart refractory, decay and moisture resistant properties to the lumber by impregnation through a two-stage process, consisting of converting the insoluble natural mineral, e.g. magnesite, into the wood impregnating solution, followed by transforming the dissolved mineral inside the wood capillaries into an insoluble heat, decay and moisture resistant material.

This disclosure is directed to methods of separating wood veneer material by property measurements, and thereafter improving the properties of veneer material with property values lower than a target threshold value, until those materials meet or exceed that threshold values. In some aspects of the disclosure, veneer materials are prepared, non-destructively measured, and separated into passing and failing material collections. The failing material collection may then be treated to improve the density and flexural modulus of the material therein. Also disclosed herein are products and materials incorporating the treated veneer materials according to the disclosed methods.
