Lamella structure
Homogeneous glulam for tensile loads
When glulam is made from lamellas of only one grading class , it is referred to as homogeneous glulam. Components subjected to tensile stress should have a homogeneous structure.
Combined lamella construction for beams in bending
In the case of bending beams, a combined construction using lamellas of different grading classes is possible. Higher strength class lamellas are used at the tension edge, while lamellas of the next lower strength class are used in the interior or at the compression edge.
Additional specifications for lamella construction
There are further specifications for lamella construction regarding the arrangement or rotation of outer lamellas, lamellas from two adjacent boards, and block-glued composite components.
