The Simpson S/B High-Capacity Top-Flange Joist Hanger for 3 in. x 8 in. Cold-Formed Steel Joists is a precision-engineered 12-gauge connector from Simpson designed to support cold-formed steel joists when installed to structural steel or cold-formed steel beams. Built with precision forming and rigorous quality control, this top-flange hanger delivers the dimensional accuracy and reliable load performance that cold-formed steel framing applications demand. Its G90 zinc galvanized finish adds a layer of corrosion resistance suited to demanding construction environments, while its versatile fastening compatibility makes it a dependable choice across a wide range of CFS jobsite conditions.

Key Features

• Precision forming and dimensional accuracy - ensures proper bearing area and connection alignment, reducing installation errors and improving structural confidence on every cold-formed steel framing job.
• High-capacity, top-flange design - delivers the structural strength required in cold-formed steel applications, so builders can count on consistent, load-rated performance in critical connections.
• Versatile fastening compatibility - attaches to cold-formed steel members with screws or to structural steel with powder-actuated fasteners or welds, giving contractors flexibility across different substrate conditions on the same project.
• Load-rated, tested, and code listed - provides documentation and third-party validation that inspectors and engineers require, helping projects move through approval processes with confidence.
• Made from 97mil (12 ga.) steel - heavy-gauge construction provides the strength and rigidity needed to handle the demands of high-capacity cold-formed steel joist connections.
• Zinc galvanized G90 coating and finish - offers corrosion resistance to help the connector hold up in demanding construction environments over the long term.

Why This Product

• Engineered specifically for cold-formed steel framing - the S/B hanger is purpose-built to support CFS joists and install to both cold-formed steel and structural steel beams, meaning it covers multiple connection scenarios without requiring a different product for each substrate.
• Tested and code listed for verified performance - load ratings backed by testing and code listing give engineers, inspectors, and contractors the documentation they need to specify this hanger with confidence and keep projects on schedule.
• Corrosion resistance built into the finish - the G90 zinc galvanized coating helps protect the connection over time in demanding site conditions, reducing concerns about long-term durability in the structure.
• Precision manufacturing from a trusted connector brand - Simpson quality control and precision forming mean each hanger arrives ready to install with consistent dimensions, reducing field adjustments and helping ensure a reliable bearing area and connection every time.
