Produced by gluing together timber lamellas under pressure
With the raw material being precisely planned the resulting product is strong, stable and aesthetically pleasing, therefore giving significant advantages over other structural materials.
Advantages
Aesthetically pleasing with a natural appearance
Customized sizes and lengths to meet Your needs
Dimensionally stable compared to solid wood
Light to handle and transport
Large load bearing capacity allowing large spans
Sound absorbing with good insulating properties
Fire resistant (0.7 mm/min), corrosion resistant, energy conserving
A large amount of energy is required to produce structural products
Economical in many cases compared to steel and concrete
Due to its versatility it is mostly used for roof structures and joists in the constructions such as arenas, swimming pools, schools and domestic dwelling, etc.
Variety of wood species and sizes
End product can be drilled, moulded and cut in different angles
