SORTING / STRENGTH GRADING

The sorting of timber allows us to determine whether it corresponds to specific standards. Wood which is of a poor level of quality or is inappropriate for use is therefore not a problem for consumers. Sorting is based on manual processes or on modern technologies. Those who sort sawn timber are all certified specialists. Depending on its quality, wood is used for furniture manufacturing, carpentry, construction, manufacturing of packaging, etc.
 

 
MECHANICAL STRENGTH GRADING

This is a method which looks at the strength of wood in relation to the tension of the bend. The system determines the point at which the wood might be damaged. The tension of the bend is measured with special equipment, thus specifying the resistance and class of the wood. On the basis of the results of this process and the requirements of various standards, a stamp is placed on each board to indicate its class. JSC Lindeks conducts mechanical strength grading with modern equipment from "Ersson" (Sweden) and "MPC" (UK). All of the employees who work with this equipment are certified.

 
VISUAL STRENGTH GRADING

The strength of timber depends on the type of tree and the conditions under which it grew. The extent to which wood corresponds to one or another class depends on the number
of branches, the quality of fibre, as well as gaps in the wood. Visual testing criteria determine the extent, type and number
of defects that are permissible for each class of wood.
This is a method which takes more time, but in most cases the number of defects and the extent to which the timber is appropriate for the needs of the client can be specified much more precisely.
JSC Lindeks conducts visual strength grading with technologies from "Hew Saw" and "Ersson". Certified specialists supervise the process, and a stamp is placed on each board to indicate its class.
