910×10

910x10 refers to a specific size designation, commonly encountered in the context of lumber and timber. This notation indicates the nominal dimensions of a piece of wood, meaning its approximate rough-sawn size before it has been planed or finished. The first number, 910, represents the width in millimeters, and the second number, 10, represents the thickness in millimeters. Therefore, a 910x10 piece of wood would be approximately 910 millimeters wide and 10 millimeters thick.

In practical applications, the actual finished dimensions will be smaller due to the planing process, which smooths the surfaces and makes the wood more uniform. For example, a 910x10 piece might finish to a size closer to 900x8 millimeters or similar, depending on the milling standards and the amount of material removed. This size designation is typically used in international markets or for specific construction or manufacturing purposes where metric measurements are preferred. It is important for users to be aware of the difference between nominal and actual dimensions when purchasing or working with lumber to ensure accurate material calculations and project outcomes. The 910x10 size might be less common than standard lumber dimensions found in imperial systems, suggesting its use in specialized applications or regions.
