Glulam beams are used as supporting columns and load-bearing elements of timber frame houses. The moisture content of 10-12% across the section. They have a stable geometric shape, not transformirovalsya, do not crack unlike the wooden planks from the array. This material has a greater ratio of strength and bearing capacity than wooden beams of solid wood. They are not limited by the size of the log, which gives the possibility of overlapping large spans and buildings. The advantage of this material compared to steel and reinforced concrete beams is their low thermal conductivity and a small specific gravity. Glued wood products simplify the Assembly of structures. So they found wide use in the installation of complex roofs (ice rinks, shopping malls, water parks), were used in the reconstruction of the Trinity Cathedral in St. Petersburg, etc.

Laminated wood beams are used for the manufacture of slabs - design of the building, dividing it into stories. Hardwood floors make installation easier and have a low thermal conductivity compared with steel or concrete products. They overlap for the most reliable material as the rafters – load-bearing construction of pitched roofs. Mauretania elements of the lower support trusses and designed to distribute loads in the slabs. Glued wooden beams are used as supporting columns and other force elements. Glued beams and rafters are fabricated using the equipment of companies «Grikon», «Weining», «Polzer», «Rex», «Spanevello», «Hundegger».
After a bonding end and vertical presses they ostrugivajutsja rafters and treated with antiseptic. These wood items in automatic mode, cut the necessary holes and gashes for quick installation on site. If necessary, they are tense with reverse camber or arch - it enhances the strength of the slab.
For the manufacture of these materials, laminated veneer lumber and trusses using materials softwood (spruce, pine). Their humidity during production and acceptance must be within 2 12%. When bonding is applied, two-component structural adhesive for wooden bearing structures, the trademark "PI Bond" model PI-111. Manufacturer: Oshika corporation 1-4-21 Funado, Itabashi-KU, Tokyo Japan 174-0041. For transporting glulam beams are shipped Packed with six sides in plastic wrap.
The main advantages of wooden ceiling elements from an array: by removing defects and gluing the boards with the opposite direction of wood fibers glued beams have a higher strength ratio and bearing capacity. Humidity of 10-12% over the entire section prevents cracking and deformation. A wide range of sizes (height from 160 to 1500 mm., thickness from 60 to 280 mm and length up to 18 meters or more) makes it possible to overlap large spans and buildings. We manufacture in Saint Petersburg and sold in Russia and CIS countries: the simulator logs, construction materials, slabs, rafters, stairs, block-house, Windows, doors and other timber products.
