This unpolished OSB board is a versatile construction panel designed for structural applications where a raw finish is acceptable. Measuring 2500 mm in length and 1250 mm in width with a thickness of 12 mm, it provides a stable and durable surface for various building needs. Because the surface is not sanded, it is well-suited for use in areas that will be covered by other materials, such as flooring underlays or wall sheathing, making it a practical choice for contractors and DIY enthusiasts working on interior framing or temporary structures.
