The Simpson IUS3.56/16 Galvanized Face-Mount Joist Hanger is a hybrid hanger from Simpson that combines the advantages of face-mount and top-mount hanger designs into a single, versatile connector engineered for 3-1/2 in. x 16 in. engineered wood members. Designed to provide reliable support underneath the joist, rafter, or beam, the IUS series is fully compatible with shallow-flange I-joists and delivers a fast, secure connection that keeps structural framing on schedule and on spec.

Key Features

• Strong-Grip seat with snap-in I-joist positioning - lets the joist lock firmly into place without extra hardware, saving time and reducing the chance of misalignment during installation
• Easy-to-reach face nail locations and self-jigging locator tabs - guide the hanger into correct position automatically and put fastener points right where your hammer or gun needs them, speeding up every connection
• Hybrid face-mount and top-mount design - gives framers the flexibility of a face-mount hanger with the bearing benefits of a top-mount style, making the IUS series adaptable to a wider range of framing conditions than a conventional single-style hanger
• Full compatibility with shallow-flange I-joists - ensures a proper fit on the engineered lumber most commonly used in modern floor and roof systems, eliminating guesswork at the jobsite
• 18-gauge steel construction - provides the structural rigidity needed to carry joist loads reliably without adding unnecessary bulk to the connection
• G90 zinc galvanized coating - delivers extra corrosion resistance to protect the hanger in demanding environments where moisture exposure is a concern

Why This Product

• Faster installation from start to finish - the combination of a Strong-Grip snap-in seat, self-jigging locator tabs, and accessible face nail positions means fewer steps and less repositioning on every joist, directly reducing labor time on the job
• Purpose-built for engineered wood framing - the IUS series is specifically designed for shallow-flange I-joists, so contractors working with engineered lumber get a hanger that fits correctly and performs as intended rather than a generic solution that may require field modification
• Corrosion resistance you can count on - the G90 zinc galvanized finish protects the steel in wet or high-humidity framing environments, helping maintain connection integrity over the long term
• One hanger, two installation advantages - the hybrid design that draws from both face-mount and top-mount hanger technology gives builders a more adaptable connector, reducing the need to stock multiple hanger types for similar applications
