Tolko Laminated Strand Lumber (LSL) | Engineered Wood Products

Engineering Better Solutions - Without Compromise

Nature doesn’t design trees to become lumber – but we do. Our line of LSL, EWP and Industrials is engineered for performance, consistency, and efficiency, allowing you to stop worrying about your material and focus on your job.

Calculated Perfection. Engineered Performance.

By peeling apart fibre strand by strand, we’re able to piece it back together to optimize the structural properties of each piece of lumber. With complete control over the quality of each piece of lumber, we can provide a superior product to suit the unique needs and budgets of builders.

Tolko’s line of LSL includes T-TEC LSL and Tolko LSL Industrials. Each product is designed to meet evolving design requirements and the demanding expectations of builders and manufacturers.
