The Simpson 2-5/16 x 18 Top Flange I-Joist Hanger is a welded, heavy-gauge steel hanger engineered to support joists on purlins or beams across a wide range of structural framing conditions. Built by Simpson and finished with Simpson Strong-Tie Gray Paint, this top-flange hanger accommodates demanding skewed and sloped framing configurations that fixed hangers cannot address, making it a reliable choice for wood-to-wood, wood-to-steel, and cold-formed steel framing connections.

Key Features

• Welded top-flange design for joist support on purlins or beams - transfers loads efficiently without requiring additional blocking or custom fabrication at the bearing point.
• Adjustable skew up to 84 deg. - handles highly angled framing layouts that standard fixed hangers simply cannot accommodate, reducing the need for field modifications.
• Adjustable slope up to 45 deg. - supports pitched or sloped roof and floor framing conditions, giving installers flexibility on complex structural projects.
• 97 mil (12 gauge) stirrup construction - provides the structural strength needed for demanding load-carrying applications while maintaining a practical installed profile.
• Simpson Strong-Tie Gray Paint finish - delivers corrosion resistance appropriate for standard interior framing environments, with select models available hot-dip galvanized for more demanding conditions.
• Approved for wood-to-wood, wood-to-steel, and cold-formed steel framing - a single hanger solution that works across multiple structural systems, reducing the need to stock multiple connector types.
