The Simpson S/B3.12/12 High-Capacity Top-Flange Hanger is a precision-formed cold-formed steel connector engineered by Simpson to support 3 in. width x 12 in. height cold-formed steel joists in demanding structural framing applications. Manufactured from 97mil (12 ga.) steel and finished with a Zinc Galvanized, G90 coating, this top-flange hanger installs to structural steel or cold-formed steel beams, delivering the load-rated performance and dimensional accuracy that CFS construction requires. Whether you are working on light gauge steel framing for commercial or residential builds, this hanger is built to meet the connection demands of every cold-formed steel application.

Key Features

• Precision forming for dimensional accuracy - ensures proper bearing area and a consistent, secure connection at every installation, reducing field adjustments and rework.
• High-capacity, top-flange design - transfers loads effectively at the top of the joist, maximizing structural performance in cold-formed steel framing systems.
• Versatile attachment options - attaches to cold-formed steel members with screws or to structural steel with powder-actuated fasteners or welds, giving contractors flexibility across different jobsite conditions.
• Load-rated, tested, and code listed - provides verified load values and code compliance documentation, supporting project approvals and inspections with confidence.
• Made from 97mil (12 ga.) steel - delivers the rigidity and strength required for high-capacity joist support in light gauge steel construction.
• Zinc Galvanized, G90 coating - provides corrosion resistance suited to cold-formed steel environments, helping protect the connection over the long term.

Why This Product

• Built for the full range of CFS applications - Simpson designs these cold-formed steel connectors to meet the strength and performance requirements of every CFS project, from smaller residential work to large-scale commercial framing.
• Multi-substrate compatibility saves time on mixed-structure jobsites - the ability to attach to both cold-formed steel and structural steel using screws, powder-actuated fasteners, or welds means one hanger works across the varied beam conditions commonly encountered in CFS construction.
• Precision manufacturing reduces installation error - the high-capacity, top-flange design is produced with strict quality control, helping ensure proper bearing area and connection geometry right out of the box.
• Code-listed with verified load ratings - tested and listed performance data gives engineers, contractors, and inspectors the documentation they need to move projects forward without guesswork.
