Product Features

  • 100% imported

    OSB products are produced by the largest OSB OEM in Europe and America. Upholding the 3A standard (Anytime, Anywhere, Anypiece), we promise to provide every piece of “OU SONG” board which is in compliance with LY/T1580-2010, EN300-2006, PS2-10, GB/T18580-2017, and other related standards.

  • Top - level environmental protection

    "OU SONG" board is the premium eco-friendly material which is ideal for creating a healthy and comfortable space, as its formaldehyde emission is only 0.3-0.5mg/100g (mean value obtained from the test), which is equal to 0.003-0.005ppm (formaldehyde naturally contained in wood; for instance, an oak emits 0.009ppm of formaldehyde), far below the E0 European formaldehyde emission standard (5mg/100g).

  • 100% fresh pine as raw material

    100% fresh Euro-pine or Ray-pine is used as raw materials, with the bark peeled.

  • Stable structure without deformation

    The product is of three-layer structure, in which the core layer and the surface layer is arranged in a crisscross pattern, effectively eliminating the internal stress of the wood and keeping the whole structure even and stable.
