The Simpson Concealed-Flange Heavy Face-Mount Hanger HUC5.31/11 is an engineered structural connector from Simpson built for heavy structural framing applications where both performance and finished appearance matter. Its face-mount joist hanger design integrates concealed header flanges that keep the connection profile clean and unobtrusive - making it a practical choice for exposed framing conditions in residential and commercial construction where visible structural members are part of the design.

Key Features

• Concealed Header Flanges - Hidden flanges produce clean, unobtrusive visible lines once installed, so exposed structural framing looks intentional and refined rather than cluttered with hardware.
• Heavy Face-Mount Design - The face-mount configuration allows direct attachment to the header face, simplifying installation in both new construction and retrofit framing assemblies that require reliable joist connections.
• 14-Gauge Steel Construction - Fabricated from 14 ga. (68 mil) steel, this hanger delivers the load-bearing capacity and structural integrity required in demanding heavy framing applications.
• Galvanized Finish - The galvanized coating provides corrosion resistance, helping maintain structural reliability over the long term in typical framing environments.
• Broad Application Compatibility - Approved for heavy structural framing assemblies, residential and commercial face-mount joist connections, and projects where a clean header-to-joist connection profile is desired in visible areas.

Why This Product

• Aesthetics without compromise - The concealed-flange design solves a real problem in exposed framing: you get the structural strength of a heavy-duty hanger without the visual bulk of visible flanges interrupting the finished look.
• Heavy-duty gauge for demanding jobs - At 14 ga. (68 mil), this hanger is built for applications that require enhanced strength and elevated safety margins, giving builders and engineers confidence in the connection.
• Trusted domestic manufacturing - Produced in the United States, the HUC5.31/11 reflects consistent quality control standards that professionals rely on for structural connectors in critical framing assemblies.
• Versatile across project types - Whether the application is residential or commercial, and whether the framing is hidden or exposed, this hanger adapts to both structural requirements and aesthetic considerations in a single product.

Frequently Asked Questions

What does "concealed-flange" mean, and why does it matter?

The concealed-flange design means the header flanges are hidden once the hanger is installed, resulting in clean, unobtrusive visible lines. This makes the HUC5.31/11 especially well-suited for exposed framing conditions where the structural members remain visible and aesthetics are a consideration alongside performance.

What gauge steel is the HUC5.31/11 made from?

The HUC5.31/11 is fabricated from 14-gauge (68 mil) steel, which qualifies it as heavy-duty construction designed to deliver superior strength and load-bearing capacity in demanding structural applications.

How is the HUC5.31/11 installed?

This hanger uses a face-mount design, meaning it mounts directly to the face of the header or beam. This approach is intended to provide straightforward installation while ensuring reliable load transfer between the supported joist and the header or beam.

What finish does the HUC5.31/11 have, and does it offer corrosion protection?

The HUC5.31/11 features a factory-applied galvanized finish. This galvanized coating is intended to help resist corrosion, contributing to extended service life in demanding structural environments.
