T-TEC LSL Joists - Tolko Industries
T-TEC LSL Joists logo

Your floor and roof joists provide the backbone for your building.

They are responsible for transferring loads and creating the overall stiffness and strength of the structure. T-TEC LSL joists are made with laminated strand lumber (LSL) and therefore provide true consistency and uniformity.
