Production and Delivery
Sawn timber manufacturing
Sawn timber manufacturing is a highly automated process. It proceeds in the order of the the process.
After sorting and measuring the log, the actual sawing process begins. Process begins with peeling and continues with demonstration of sawing techniques, sawing machines, saw lines, by-product handling and blade technology. This is followed by fresh sorting, ribbing, drying, dry sorting and packing of lumber.
Timber can be dried in chamber and progressive kilns.
The moisture content of exported dry sawn timber is 20 +4%, but depending on the application, the sawn timber can also be dried according to the customer’s order.
The stamp at the end of the piece, i.e. the shipping mark, indicates its manufacturer and quality. Stamps used by different manufacturers can usually be found on the company’s website.
In strength-graded sawn timber, the pieces are sorted and stamped according to an agreed standard.
The timber is tied with straps and usually wrapped in plastic wrap to protect the pieces during the transfer, transportation and storage stages. The package is marked with product information. The size of the finished package is about 1×1 m. The length of the package depends on the length of the sawn timber.
Visual quality and strength
Timber pieces can be sorted according to both visual quality and strength. In quality sorting, a piece is evaluated on the basis of all four sides, as described on grading page. Strength graded timber is used in load-bearing structures.
Visually or by machine
Structural timber refers to spruce or pine timber that is used for load-bearing structures or part of such a structure and for which there are set minimum strength and elasticity requirements. Structural timber is graded mechanically using different machine vision, X-ray, ultrasonic or natural frequency methods or visually. In visual strength grading, the criteria for determination include the number and location of branches, the twist of the sawn timber piece and cracks. Machine strength grading is based on mechanical measurements of the timber’s density and knots
Machine-graded sawn timber must bear the CE marking, which indicates that it complies with a harmonized product standard. The CE-marked product meets the essential safety and health requirements of the Construction Products Directive.
