Large span widths are no problem for glued laminated timber. However, the limits for very long glulam components are soon reached when it comes to overseas projects or narrow construction site access roads. For more than ten years now we have been realizing projects with our specifically developed, patented and approved all-in-one solution HESS LIMITLESS. Arbitrarily long glued laminated timber beams are specially pre-fabricated on our site and subdivided into short, convenient segments. The segmentation facilitates a flexible, safe and economical worldwide transport by trucks or in shipment containers. On the construction site, experienced assembly specialists subsequently glue the subsegments by using our patented HESS LIMITLESS joint system and prepare them for assembly.

The unique degree of effectiveness [η = 1] of the pure wood-wood connection results from the optimal interaction of the general finger joint and the so-called scarf joint. The scarf joint is a specially designed fitting piece with an angular cut on both sides and which, depending on the load case, is applied either on the upper or bottom side of the glued laminated timber construction part. In addition, both the subsegments and the scarf joint are equipped with specially sorted premium lamellas on the side that is under tensile load. The ingenious combination of the different components lessens the strength reduction the general finger joint and enables the realization of highly economical and optimally dimensioned glued laminated timber constructions.
