steamtreated
Steam-treated refers to materials that have undergone a treatment in which steam or water vapor is used as part of the processing, most commonly in wood. In wood, steam treatment is a form of thermal modification where the timber is heated in a steam-rich environment to elevated temperatures, typically around 160 to 260 degrees Celsius. The steam atmosphere helps drive chemical changes in the wood and serves as a heat carrier. The process is usually performed in a controlled chamber, involving a gradual temperature rise, a soak at the target temperature, and a controlled cooling and conditioning phase. The exact parameters vary by species and end use.
The primary goals of steam-treated wood are to improve dimensional stability, reduce swelling and shrinkage, and
Applications and market terms vary. Steam-treated wood is marketed as thermally modified or steam-treated wood and
Limitations can include higher cost and potential changes in strength or coating adhesion that are species-
