Product Description
The Simpson Strong-Tie MIU3.12/9 is a galvanized face-mount I-joist hanger engineered for commercial and high-load I-joist applications. Designed to accept a 3 in. x 9-1/2 in. engineered wood member, this hanger provides dependable support underneath the joist to create a strong, reliable connection without requiring web stiffeners. Constructed from 16-gauge steel with a G90 zinc galvanized coating for enhanced corrosion resistance, the MIU series is a trusted solution across a diverse range of structural framing applications. Positive-angle nailing (PAN) geometry is built into the design to minimize flange splitting while enabling faster, more efficient installation.
