Areas of application • Walls and ceilings • Visible roof structures • Post-and-beam construction • Timber frame and skeleton construction • Visible components for very demanding designs Quality for highly visible timber structures MMvistaline is a rectangular-shaped, glued lamella beam for visible applications in private and commercial buildings. MMvistaline solid timber beams consist of 2 or 3 lamellas that are vertically glued with one another. A special cutting pattern, the exceptional sorting and the careful drying of the spruce wood form the basis for the unique visual quality of the...

Span table Z-9.1-440: Permissible bending stress: Permissible shear stress: Permissible deformation: Span tables for single span beams These tables are only to be used for predimensioning purposes. Prior to implementation a precise structural analysis must be carried out in accordance with the currently applicable dimensioning standards in every case. System assumptions: • Uniform loading • Beam is supported against lateral shifting; no risk of tilting • Shear and creep deformations are not taken into account • Uniform load q is composed of: g: permanent load, incl. dead load of the beam p:...
