T-TEC LSL Joists

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