Product Description
The Simpson MIU3.56/20 Face-Mount I-Joist Hanger by Simpson is purpose-built for commercial and high-load I-joist applications, delivering a strong, reliable face-mount connection for 3-1/2 in. x 20 in. engineered wood members without requiring web stiffeners. Constructed from 16-gauge steel with a G90 zinc galvanized finish, this hanger is built to handle demanding structural connections where performance and durability are non-negotiable. The MIU series incorporates positive-angle nailing (PAN) technology, making it a practical choice for contractors who need both speed and precision on the job site.
Key Features
- Positive-angle nailing (PAN) - minimizes splitting of the I-joist flanges while allowing nailing from a more efficient angle, saving time and reducing material damage during installation
- No web stiffeners required - simplifies installation on commercial and high-load I-joist applications, reducing labor steps and keeping your project on schedule
- 16-gauge steel construction - provides the structural strength needed for demanding load conditions in engineered wood framing
- G90 zinc galvanized finish - delivers extra corrosion resistance, helping the hanger hold up in moisture-prone environments over the long term
- Non-modifiable design - ensures the hanger performs exactly as engineered and rated, protecting the integrity of the connection and keeping installations code-compliant
Why This Product
- Engineered for heavy commercial loads - the MIU series is specifically designed for high-load I-joist applications, making it a dependable choice when standard hangers are not rated for the job
- Faster installation without sacrificing connection quality - positive-angle nailing lets crews nail from a better angle, cutting installation time while maintaining a strong, split-free flange connection
- Built for engineered wood with precision sizing - sized specifically for 3-1/2 in. x 20 in. I-joist members, this hanger fits engineered lumber accurately and eliminates guesswork in the field
- Corrosion-resistant for lasting performance - the G90 galvanized coating provides a layer of protection that helps maintain structural integrity in conditions where bare steel would be at risk
