We offer wood SK-Beams with a reinforcement beam made of OSB. The company’s products are certified (ETA 17/0424), the components in service have the corresponding European certificates. Beams are designed and manufactured at their own production facilities in the Vilnius region and are used as load-supporting units of floorings, rafter structures and framed wall elements for the construction of low-rise residential and public buildings. Wood I-beams are used in houses made of bricks, lightweight concrete block, timber, in frame houses and effectively replace the floorings made of reinforced concrete slabs, timber, boards, steel beams. Wood I-beams are manufactured based on OSB-3 oriented standard board (10 mm thick), the flanges are made of a board with 38×64 and 38×89 mm sections from the LVL timber. The entire production is controlled by the QCD, which is the guarantor of quality. Samples from each batch of the beams are tested in complex on a special test bench. The formula “LVL+ OSB + LVL” allows to avoid the drawbacks inherent in wood, and due to the I-section, there are high strength properties. The I-beam maintains its stiffness for the entire useful life of the building.
