The Simpson WP5.31/12 Welded Top-Flange Joist Hanger is a heavy-duty connector engineered to support I-joists and dimensional lumber on purlins or beams across a broad range of structural framing applications. Built by Simpson to handle wood-to-wood, wood-to-steel, and cold-formed steel connections, this top-flange hanger delivers reliable load transfer in both standard and complex framing layouts, including skewed and sloped configurations that demand precise angular adjustability.

Key Features

• Top-flange hanger design - seats the joist from above the supporting member, providing a clean bearing surface and simplifying installation in tight framing conditions
• Skewable up to 84 deg. - accommodates highly angled framing layouts, reducing the need for custom fabrication on projects with non-perpendicular joist runs
• Slopeable up to 45 deg. - supports pitched roof and floor framing applications without requiring specialized hardware, saving time and material costs
• Compatible with wood-to-wood, wood-to-steel, and cold-formed steel connections - gives contractors a single versatile solution across multiple structural assemblies and building types
• Supports joists on purlins or beams - suits a wide variety of structural configurations from floor systems to roof framing, expanding the range of projects where this hanger applies
• 97 mil (12 ga.) stirrup material - provides the structural thickness needed to achieve rated download capacity with a minimal number of fasteners, keeping installed costs low
• Simpson Strong-Tie Gray Paint finish - offers corrosion resistance suitable for protected interior applications, with hot-dip galvanized options available for more demanding environments

Why This Product

• Engineered for versatility across connection types - supporting wood-to-wood, wood-to-steel, and cold-formed steel framing means this single hanger model covers a wide range of structural scenarios, reducing the number of SKUs a contractor needs to manage on site
• Exceptional angular flexibility - the ability to skew up to 84 deg. and slope up to 45 deg. makes this hanger well suited for complex architectural framing where standard perpendicular hangers fall short
• Efficient fastening for lower installed cost - the welded construction is designed to reach maximum download capacity with a small number of nails or screws, reducing labor time without sacrificing structural performance
• Domestic production from a trusted connector brand - manufactured by Simpson, a recognized name in structural connectors, this hanger is produced in the United States and carries the quality standards that structural engineers and inspectors expect on the job site
