Spruce Beams

In recent years, the trend towards more ecologically friendly construction has motivated architects and engineers to use wood, a natural building material par excellence, in the most varied works as a distinctive architectural element. The charm of the wooden beams, and especially of the laminated wood, is in the possibility of the free configuration of the elements of wood and in its bearing capacity.

With the MM masterline mark Mayr-Melnhof Holz manufactures laminated beams according to DIN 1052-1 / A1, ÖNORM EN 386.

High resistance to fire

A laminated wood support structure is, in the case of fire, safer than unprotected steel since a carbonized layer is formed around the central support which reduces the supply of oxygen and heat from the outside which considerably delays the combustion. A fire resistance of 30 minutes is achieved without problems and with appropriate sections can reach 60, 90 or more time, according to the normative requirements.
