The Simpson HGLTV3.59 Heavy Top-Flange Joist Hanger is purpose-built for structural composite lumber header connections that carry high loads, supporting members sized at 3-1/2 in. x 9-1/2 in. Engineered by Simpson Strong-Tie, this hanger combines a heavy 3-gauge top flange with a 7-gauge stirrup to deliver reliable strength in demanding framing applications. The Funnel Flange design eases beam placement during installation, and top-flange nail holes are precisely sized and strategically located to prevent header degradation caused by splitting of laminations - making this hanger a dependable choice for engineered lumber joist, beam, and weld-on framing applications.

Key Features

• 3-gauge steel top flange - provides heavy-duty structural capacity suited for high-load header connections in engineered lumber framing
• 7-gauge steel stirrup - delivers a robust cradle for the supported member, maintaining consistent alignment under load
• Funnel Flange design - guides beams into position during installation, reducing placement difficulty and saving time on the job
• Precisely located top-flange nail holes - sized and positioned to minimize the risk of lamination splitting, protecting the integrity of structural composite lumber headers
• Compatible with weld-on applications - expands installation flexibility for framing scenarios where nailing alone is not the preferred method
• Simpson Strong-Tie gray paint finish - provides a consistent, recognizable finish that holds up in typical covered framing environments
• Web stiffener requirement clearly defined - when used with I-joists, the requirement for web stiffeners is established upfront, helping installers plan correctly and avoid field errors

Why This Product

• Engineered specifically for high-load SCL header applications - unlike general-purpose hangers, the HGLTV series is designed around the demands of structural composite lumber connections, with nail placement engineered to prevent lamination splitting that could compromise the header over time
• Heavy-gauge dual-component steel construction - the combination of a 3-gauge top flange and a 7-gauge stirrup means this hanger is built to handle the elevated loads common in engineered lumber framing without compromising connection integrity
• Versatile across multiple installation methods - approved for use in top-flange joist hanger applications, I-joist installations, and weld-on framing, this single hanger covers a range of structural scenarios that might otherwise require separate products
• Backed by Simpson Strong-Tie engineering - part of a trusted line of structural connectors, this hanger is made in the United States and supported by the technical documentation and application guidance that professional framers and contractors rely on
