Frequently Asked Questions

What makes the HUC5.31/14 different from a standard joist hanger?

The HUC5.31/14 is a heavy-duty hanger built from 14 ga. (68 mil) steel, which provides additional strength and elevated safety factors compared to lighter-gauge standard hangers. It also features concealed header flanges, which eliminate visible hardware on the header face - a distinction that matters in exposed or architectural framing conditions where appearance is a consideration.

Is this hanger suitable for exposed framing applications?

Yes. The concealed header flange design is specifically intended for use in exposed framing conditions. Because the flanges are hidden against the header rather than wrapping visibly around it, the installed result presents cleaner, more unobtrusive visible lines suited to finished or architectural assemblies.

What finish does the HUC5.31/14 have, and what environments is it appropriate for?

The HUC5.31/14 has a galvanized finish, which provides corrosion resistance suitable for a variety of interior and protected exterior structural applications.

How is the HUC5.31/14 installed?

The HUC5.31/14 uses a face-mount design, meaning it attaches directly to the face of the header or beam. This approach simplifies installation across a wide range of framing configurations without requiring the hanger to wrap around or be recessed into the supporting member.
