Glue-laminated beams

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.
