Strength graded wood

Strength graded material

The rough-planed or calibrated surface is flattened, but it may not be perfectly smooth. When rough planing, the planer’s blade touches most of the surface. The most common cross-sections of calibrated and strength graded structural timber produced for the Estonian market are: 45mm x 70/95/120/145/170/195/220 / 245mm. All construction products are calibrated (planed to exact dimensions), strength graded by a machine and CE-marked. Demand for high-quality and durable frame materials has increased in both manufacturing and construction. You can buy C24 strength graded material from us.
