The Simpson HGLTV5.518 Heavy Top-Flange Hanger is a heavy-duty structural connector from Simpson Strong-Tie built specifically for structural composite lumber header applications that require high load capacity. Engineered for 5-1/4 in. x 18 in. engineered lumber members, this top-flange hanger features nail holes precisely sized and located to prevent splitting of laminations, protecting the structural integrity of SCL headers under demanding loads. The Funnel Flange design simplifies beam seating during installation, making this hanger a dependable solution for professionals working with large-dimension engineered wood in joist, rafter, and beam support connections.

Key Features

• Top flange constructed from heavy-duty 3-gauge steel - delivers the rigidity and load-bearing strength required for high-capacity structural composite lumber header connections.
• Stirrup built from 7-gauge steel - provides a robust cradle for the supported member while keeping overall hanger weight practical for handling on the job site.
• Nail holes precisely sized and located to prevent lamination splitting - preserves the full structural integrity of engineered lumber headers so load ratings are maintained over the life of the connection.
• Funnel Flange design - guides large-dimension beams into position quickly and accurately, reducing installation time and the risk of misalignment during placement.
• Compatible with weld-on applications - gives fabricators and contractors the flexibility to integrate this hanger into prefabricated assemblies where welding is the preferred attachment method.
• Web stiffeners required with I-joists - when properly installed with stiffeners, this hanger ensures correct load transfer across the full depth of the I-joist web, maintaining connection performance.
• Simpson Strong-Tie gray paint finish - provides a durable protective coating suited to the dry, interior structural environments where engineered lumber headers are commonly used.

Why This Product

• Purpose-built for high-load engineered lumber applications - the HGLTV5.518 is specifically designed for structural composite lumber header connections where standard hangers cannot meet the load demands, making it a direct fit for large-dimension SCL and engineered wood framing systems.
• Dual-gauge steel construction optimizes strength where it matters most - the 3-gauge top flange handles the concentrated forces at the bearing point while the 7-gauge stirrup secures the member, giving the assembly targeted strength without unnecessary bulk throughout.
• Fastener-specific engineering protects the host member - nail hole placement is deliberately engineered to avoid degrading the header through lamination splitting, so the engineered lumber performs to its rated capacity after installation.
• Versatile installation options including weld-on capability - support for both standard nail-fastened and weld-on installation methods makes this hanger adaptable to a wider range of structural framing and prefabrication workflows.
