The direction of the glued joint (horizontal or vertical) is irrelevant for the load-bearing capacity. Unless the manufacturer declares different strengths in the direction of both axes, which is not done by now. If a particular direction is preferred for the glued joint, this must be specified when the order is placed. Preferred cross-sections for other wood species are available on request.
1) According to EN 14080 these cross sections are denominated as glulam, but typically they are subsumed as glued solid timber.
