I-Joists are engineered wood structural components shaped like the letter �I,�
designed to provide high strength
and stability while using less material than solid timber beams. They consist of two flanges
(top and bottom)
made from LVL or solid wood, connected by a vertical web made from OSB (oriented strand
board) or plywood.

These joists are widely used in residential and commercial construction for floor systems,
roof framing, and
ceiling structures. Their design allows them to span long distances with minimal deflection,
making them highly
efficient for modern building projects.

I-Joists are valued for their strength-to-weight ratio, dimensional stability, and ease of
installation. They reduce
warping, twisting, and shrinking issues common in solid timber, while also allowing space
within the web for
plumbing, electrical, and HVAC installations.
