The shipping marks stamped on the ends of sawn timber inform the recipient who the timber producer is as well as the type and grade of the sawn timber.
Sawn timber is classified into various grades based on its technical and visual properties. The technical properties include the dimensions, moisture content and warping of the sawn timber. The visual properties include the location, size, number, quality and composition of knots and warps.
Our sawn softwood grading softwood use a seven-step scale, which includes:
- US – Grade I-IV
- V – Grade V
- VI – Grade VI
- Domestic (Grade VII) and schaalboards
The US grades (US standing for unsorted) that are the highest contain the grades US I – IV. The majority of Metsä Fibre’s spruce sawn timber, which is of a consistent quality, falls under the US I – IV grades.
The shipping marks which were all sawmill-specific have been replaced by the new brand image. This has led to a new design based upon the Metsä logo and a mark indicating the timber’s grade. For spruce sawn timber, the logo’s base colour is green, and for pine sawn timber, it is red.
