MM masterline is the international quality brand for glulam beams from the Mayr-Melnhof Holz Group. It is engineered from individually strength-graded lamellas, which are planed & parallel-glued. These glulam elements offer a competitively priced solution to applications where high load-bearing capacity, outstanding dimensional stability, as well as design versatility are needed. The possibility to combine high-quality straight, curved, and customized load-bearing components allows architects unlimited freedom of design. Mayr-Melnhof Holz offers a full range of glulam products from standard stock goods through to complicated special components.

MM masterline glulam beams, like all the products in our range of engineered timber, are produced under strict quality control and are PEFC certified. As a natural and renewable building material that stores CO2, the use of MM Masterline makes an important contribution to active climate protection.
