CLTimber Bay System
Sterling Structural is pushing the boundaries of what mass timber can do—starting with smarter, more sustainable warehouses, data centers and “big boxes”. Building on our expertise delivering large-scale industrial projects, we developed the CLTimber Bay System: a prefabricated, high-performance solution tailored to meet the growing demand for sustainable, occupant- friendly industrial and commercial buildings.
As corporate real estate evolves, developers are prioritizing smarter building systems that support both people and the planet. Our CLTimber Bay System responds to this shift by combining the environmental benefits of mass timber with
the speed and efficiency of a pre-engineered solution. Optimized for performance, flexibility, and constructability, it’s a system that delivers— on site, on time, and on budget.
Comprehensive, Fully Engineered Building Solution ideal for:
- Warehouses
- Datacenters
- Big Box Stores
Completing the building envelope quickly is a priority, which is why we offer the option to supply panels with factory-applied WRB to fast-track progress. CLT offers a continuous structural surface, attaching racking, mechanical systems, or tenant improvements is simple — no additional blocking or costly field coordination required.
Need comparative data? Sterling and its complementary product, engineering and installation partners are ready to provide environmental product data, material weight, logistics, and schedule benefits over traditional tilt-wall construction.
CLTrainer Mock-Up
Sterling Structural is excited to offer a small-scale mass timber building mock-up designed to educate and train installers on the fundamentals of mass timber construction. This hands-on learning tool showcases key components of prefabricated CLT and glulam systems, demonstrating best practices for installation, connection detailing, and material handling.
Built to reflect real-world construction scenarios, the mock-up provides experience that helps you gain confidence working with mass timber, in preparation for the growing demand in sustainable, high-performance building solutions. Through this initiative, we aim to strengthen workforce readiness and bridge the knowledge gap in mass timber construction techniques.
What’s Included:
- CLT Panels – The large majority of mass timber projects include CLT panels, the mock-up features both 3-ply and 5-ply CLT to familiarize teams with different panel weights and handling requirements.
- Floor & Roof Systems – Users will learn panel-to-panel spline connections that are critical to a building’s lateral strength. The mock-up includes both recessed plywood splines and surface-mounted straps, as both are common in the industry.
- Glulam Column Connections – Require different connections based on structural loads, fire rating for the super structure, and aesthetics. The kit includes column base connections to include a raised stand-off typical with concrete topping slabs.
- Glulam Beam Connections – To demonstrate more advanced connection techniques, the kit includes knife plate connections and concealed hangers, both of which require precise installation. Exposed bucket connections are not featured, as they are simpler to install and require less specialized training.
