GBM's slab beams are currently the most resistant in the market.
Available in various sizes, they are made of solid fir.
GBM H20 and GBM H20+ slab beams are currently the most resistant in the market.
Available in various sizes, the outer parts are made of selected quality solid fir, comb-like coupled using the finger-joint technology, and with a three-layer core.
Upon request, they may come in plastic protections so as to reduce the risk of scratching the outer parts of the beams.
Below are the features of GBM's slab wooden H20 beams
Thanks to their perfect assembly, GBM H20 and GBM H20+ beams can be cut and used at any length.
|Dimension||Values (a)||Tolerance (b)|
|Beam height||200 mm||± 2 mm|
|External height||40 mm||± 0,6 mm|
|External width||80 mm||+ 0,8 mm/-1,2 mm|
|Core thickness||28 mm||± 1 mm|
a) The values are applied with wood humidity at 12% ± 2%
b) In compliance with the SIST EN 13377:2002 standards
|Certificates||DIN1052-1:1988-04||DIN1052:2008-12 / Eurocode 5|
|Resistance||Bending||Load capacity characteristic limit|
|Shear strength||ZUL Q = 11,0 kN||Vk = 23,9 kN|
|Bending moment||ZUL M = 5,0 kNm||Mk = 10,9 kNm|
|Load||-||Rb,k = 47,8 kN|
|Sectional modules (1)||Wx= 461 cm3|
|Geometric moment of inertia (1)||Ix= 4.613 cm4|
|Modulus of elasticity||E = 10.000 N / mm2|
|Shear modulus||G = 600 N / mm2|
1) The values of the sectional modules and the geometric moment of inertia are applied to new beams. A higher safety value must be used for worn out beams.
As a tool, the GBM slab H20 beams technical data sheet is useful for worksite operators. The technical data sheet instructs the operator on the main features of the beams.
