Mass timber products
We offer custom solutions and standard Cross-laminated Timber (CLT) Cross-laminated timber (CLT) is a high-performance engineered wood product made by layering lumber at perpendicular angles and bonding them with structural adhesives. This crosswise configuration delivers strength, rigidity, and dimensional stability—ideal for floors, walls, and roof systems across a range of building types. , Glulam (GL) Glulam (GL) is formed by laminating multiple layers of dimensional lumber, bonded with structural adhesives and aligned in the same direction. This orientation delivers exceptional strength and load-bearing capacity, making it well-suited for beams, columns, and arches. Its versatility extends to a wide range of shapes and sizes—including curved forms—offering both structural performance and design flexibility. , and structural Connection Mass timber connections are the structural joinery systems—such as screws, bolts, plates, and proprietary hardware—that transfer loads between timber elements like beams, columns, and panels. Depending on the unique constraints of each project, connection choices are influenced by a range of factors, including aesthetics, load-bearing capacity, fire-rating requirements, quality assurance standards, cost, and constructability. products for your building needs.
Discover the benefits of wood
The structural, aesthetic, and biophilic properties The innate human tendency to connect with and seek out nature and natural elements, which has been shown to have positive effects on physical and mental health, productivity, and well-being. of wood are limitless. Whether as a load-bearing element or interior finish, wood enhances the well-being of the people who use them.

Product FAQs
What mass timber products does Mercer supply?
We manufacture cross-laminated timber (CLT) and glulam (GL) beams and columns across our three North American facilities. Our product lineup supports a wide range of structural systems, including commercial, multifamily, institutional, and civic projects.
What are your maximum product sizes?
We manufacture:
- CLT panels up to 12 feet wide and 60 feet long
- Glulam beams up to 8 feet deep, with lengths up to 110 feet, subject to shipping logistics.
For span charts, panel thicknesses, and structural properties, please visit our Product Specifications section.
What species do you use in your CLT and glulam?
We source regionally:
- Alaskan Yellow Cedar (AYC)
- Douglas Fir- Larch (DF-L)
- Hem-Fir (HF)
- Southern Yellow Pine (SYP)
- Spruce-Pine-Fir (SPF)
All fiber is sustainably sourced and third-party certified.
What certifications and approvals do your products carry?
All Mercer mass timber products are:
- APA-certified for structural use
- Tested for fire resistance, acoustics, and seismic performance
- Compliant with IBC, NBCC, and other North American codes
Full documentation is available, please visit our Product Specifications section.
Do you offer support for connections and detailing?
Yes. We collaborate with design teams to ensure structural efficiency and constructability, from typical connection guidance to custom hardware solutions. We also offer a downloadable Connection Catalog—launching soon—to support early-stage detailing.
Do you offer product recycling or end-of-life services?
We reduce waste upstream through optimized panel layouts and smart offcut strategies. Any remaining is chipped and included in our processing residuals, which are sold to a fiberboard manufacturer in Oregon, giving that material a second life. While we do maintain standard waste services for non-recyclable materials, we aim to keep our production streams as close to zero waste as possible. Circularity remains a key focus of our sustainability roadmap.

How is mass timber made?
At MMT, we manufacture mass timber by layering, gluing, and pressing dimensional lumber into high-performance structural elements. Two of the most common types – cross-laminated timber (CLT) and glue-laminated timber (glulam) – are each engineered with distinct layering techniques to serve different structural purposes.
Design capabilities with mass timber
From exposed wood columns to sweeping, curvilinear roofs, the expressive potential of mass timber is boundless.
