Product Description
The Simpson MIU3.56/9 Face-Mount I-Joist Hanger by Simpson is built for commercial and high-load engineered wood applications, delivering a strong, reliable connection beneath the joist without requiring web stiffeners. Engineered to fit a 3-1/2 in. x 9-1/2 in. I-joist member, this face-mount hanger simplifies structural connections where performance and efficiency matter most.
Key Features
- Positive-angle nailing - minimizes splitting of the flanges while allowing nailing from a better angle, helping crews work faster with less risk of damaging the joist.
- No web stiffeners required - designed specifically for high-load I-joist applications without this added step, reducing labor and simplifying the installation process.
- 16-gauge steel construction - provides the structural strength and rigidity needed for demanding commercial framing applications.
- Zinc Galvanized (G90) coating - adds a protective layer against corrosion, making this hanger suitable for use in environments where moisture exposure is a concern.
- Fixed, non-modifiable design - ensures the hanger maintains its engineered load ratings and geometry as intended, so you can trust the connection performs as specified.
Why This Product
- Built for high-load commercial work - the MIU series is engineered specifically for commercial and high-load I-joist applications, giving contractors a hanger rated for the demands of larger-scale structural framing.
- Faster installation without compromise - positive-angle nailing and the elimination of web stiffener requirements combine to cut installation time while maintaining a strong, code-friendly connection.
- Corrosion resistance built in - the G90 galvanized finish provides durable protection against corrosion, adding long-term reliability to the connection wherever the hanger is used.
- Consistent, dependable fit - the fixed design ensures dimensional integrity is preserved every time, so the hanger performs exactly as engineered for a 3-1/2 in. x 9-1/2 in. engineered wood I-joist member.
