The Simpson WP12 Welded Top-Flange Joist Hanger is an engineered structural connector from Simpson designed to support joists on purlins or beams across a wide range of framing conditions. Built for demanding applications, this top-flange hanger accommodates wood-to-wood, wood-to-steel, and cold-formed steel assemblies, while its welded construction and adjustable geometry ensure reliable load transfer where precision and structural integrity are non-negotiable.

Key Features

• Welded Top-Flange Design - Provides a secure, rigid connection at the top of the supporting member, simplifying installation and delivering consistent structural performance in joist-to-beam or joist-to-purlin assemblies.
• Skews Up to 84 deg. - Allows the hanger to accommodate severely angled framing layouts, giving builders flexibility to handle complex structural geometry without requiring custom fabrication on site.
• Slopes Up to 45 deg. - Supports pitched roof and sloped floor framing conditions, making this connector suitable for a broad variety of residential and commercial construction scenarios.
• Multi-System Compatibility - Approved for wood-to-wood, wood-to-steel, and cold-formed steel framing applications, so one hanger model can serve across different structural systems on the same project.
• 12 Gauge Stirrup Material (97 mil) - Heavy-gauge steel construction provides the strength needed to handle demanding load conditions in structural framing applications.
• Simpson Strong-Tie Gray Paint Finish - Factory-applied finish offers corrosion resistance for standard interior and protected framing environments, with hot-dip galvanized available as an option for more demanding exposure conditions.

Why This Product

• Exceptional Angular Flexibility - With skew capability up to 84 deg. and slope capability up to 45 deg., this hanger handles angled and pitched framing assemblies that would challenge most standard connectors, reducing the need for field modifications.
• Broad Application Range - Approved for wood-to-wood, wood-to-steel, and cold-formed steel framing systems, this connector adapts to mixed-material construction environments rather than locking you into a single structural approach.
• Engineered for a Specific Joist Profile - Sized precisely for a 1-3/4 in. x 12 in. joist, the WP12 delivers a clean, accurate fit that supports proper load transfer without guesswork or makeshift adjustments.
• Trusted Simpson Construction Quality - Produced in the United States to Simpson engineering standards, this welded top-flange hanger is built to perform reliably in the structural framing applications where connection integrity matters most.
