Advancing timber innovation for a better tomorrow.

Mass timber for high-performance, low-carbon buildings

Mercer Mass Timber is the premier provider of timber building solutions in North America.

MMT is a part of Mercer International, a global leader in renewable bio-based products.  

MMT’s production capacity and service capabilities are unmatched.

Our 270,000-square-foot manufacturing facility is outfitted with the most advanced, sophisticated technology used at every step of the process to improve efficiency, transparency, and performance. We have invested the time and resources in the tools, equipment, and processes necessary to consistently deliver best-in-class mass timber products.

By taking a technology-first approach, heavily investing in R&D, and continually innovating at each step of the value chain, our portfolio of mass timber products will continue to raise the standard of quality.

We’re developing a portfolio of next-generation mass timber products, assemblies, and full-scale modular systems that will expand the horizons of what mass timber can do.

We use Design for Manufacturing and Assembly (DfMA) as a framework to facilitate an integrated partnership that ensures high quality, speed, and competitive cost thanks to our robust technology systems and high-volume fabrication.

By designing for manufacturing and assembly and utilizing Virtual Design and Construction (VDC) and BIM processes, we are able to maximize built time and reduce costs, while maintaining flexibility to configure the final product for a wide range of design expressions.
