The Simpson IUS3.56/11.88 IUS Galvanized Face-Mount Joist Hanger is a hybrid structural connector from Simpson engineered to support 3-1/2 in. x 11-7/8 in. engineered wood I-joists in residential and commercial framing. Combining the advantages of face-mount and top-mount hanger designs, this connector delivers a fast, secure connection that is fully compatible with shallow-flange I-joists. The G90 zinc galvanized coating provides extra corrosion resistance, making it a dependable long-term solution for structural framing applications where moisture protection matters.

Key Features

• Strong-Grip seat with snap-in I-joist installation - simply fasten the hanger to the header, position the I-joist, and snap into place, eliminating extra steps and reducing labor time on the job site.
• Easy-to-reach face nails and self-jigging locator tabs - speed up installation by keeping fastener points accessible and the hanger automatically positioned correctly, reducing the chance of misalignment.
• Hybrid face-mount and top-mount design - gives framers the flexibility and structural performance of both hanger styles in a single connector, suited to a wide range of engineered wood framing conditions.
• Full compatibility with shallow-flange I-joists - ensures a proper fit with the engineered lumber commonly used in modern floor and roof framing, so there is no need for field modification.
• 18-gauge steel construction - delivers solid structural integrity while keeping the hanger lightweight enough for efficient handling during installation.
• G90 zinc galvanized finish - provides extra corrosion resistance, extending the service life of the connector in applications exposed to moisture or humidity.
• Installs with 10d common nails - uses a widely available, standard fastener so there is no need to source specialty hardware to complete the installation.

Why This Product

• Faster framing with fewer steps - the Strong-Grip seat, self-jigging locator tabs, and snap-in I-joist positioning work together to cut installation time, which helps keep projects on schedule and reduces installed cost.
• Built specifically for engineered wood I-joists - the IUS series is fully compatible with shallow-flange I-joists, making this hanger a purpose-built solution rather than a generic connector adapted to fit, so structural performance is not compromised.
• Corrosion-resistant coating for long-term reliability - the G90 zinc galvanized finish goes beyond basic protection, making this joist hanger appropriate for framing environments where moisture exposure is a concern and long service life is a priority.
• Trusted hybrid design from a recognized structural connector brand - Simpson engineered the IUS series to combine the strengths of both face-mount and top-mount hangers, giving builders a single versatile connector that handles a broad range of I-joist framing applications.
