Glued laminated timber offers unique product features and myriad application options. Using precision CNC machining for assembly joints together with our long-standing technical expertise, Mayr-Melnhof Holz can offer the best solutions for the design and manufacture of special shapes and versatile structural building elements, whatever your project requires. 

The possibility to combine a variety of high-quality straight, tapered, or curved glulam beams opens up virtually endless design options. MM masterline is the international quality brand for glulam beams from the Mayr-Melnhof Holz Group. MM masterline eingineered glulam is precisely manufactured and finished on state-of-the-art CNC machining stations. The high degree of prefabrication means fast, low-dust installation at the construction site. Engineered from individually strength-graded lamellas, planed & parallel-glued, these glulam elements offer a convincing solution to applications where high load-bearing capacity, outstanding dimensional stability, cost efficiency as well as design versatility are needed.

MM masterline engineered glulam is subject to rigorous quality control during production and, like all Mayr-Melnhof Holz timber construction products, is PEFC-certified. As a natural, regrowing building material that stores CO2, the use of engineered glulam makes an important contribution to active climate protection.


Mayr-Melnhof Holz also serves as a one-stop-shop for timber engineering & turn-key construction. Learn more about our range of services at Timber engineering & turn-key construction MM complete by Hüttemann.
