In this study, taun（Pometia spp.） and birch（Betula spp.） wood were compressed by 2-3 mm of thickness and treated with pressurized steam for compression fixing. It was found that surface density of the two wood samples increased by at least 0.15 g/cm,3, with unchanged densities in inner parts of the wood samples. After being processed into wood floors, dimensional change of the wood floor samples was at least 50% lower than the requirement of the National Standard GB/T 35913-2018,and thickness recovery of taun and birch wood floor samples was only 0.04 mm and 0.13 mm respectively, that proved effective compression fixation of the pressurized steam treatment.
