Simpson Strong-Tie Top Flange Engineered Joist Hanger

Heavy-Duty Joist Support for I-Joists and Structural Composite Timber

The Simpson Strong-Tie HB Top Flange Joist Hanger is designed for robust and secure support of I-joists and engineered timber members from timber headers. Tailored specifically for use with single ply headers 89mm thick or more, this hanger provides versatility, high performance, and weld-on compatibility, making it ideal for engineered floor systems.

Key Features

• Top Flange Fixing
  Mounts securely to timber headers using a top flange for strong vertical load transfer in floor and ceiling systems.

• Engineered Timber Compatibility
  Suitable for I-joists, LVL, and structural composite lumber, accommodating modern engineered framing materials.

• Single Ply Header Use
  Specifically designed for headers 89mm or thicker, simplifying specification for common construction standards.

• Weld-On Compatibility
  For steel fabrication, the HB can be used in weld-on applications, with a 3.0mm x 50mm fillet weld required on each top flange tab. Welded configurations allow maximum load capacity as listed in technical documents.

• Slope and Skew Adjustability
  Can be sloped or skewed up to 45°, allowing it to adapt to angled joist layouts. Load adjustment factors apply—see technical documentation for specifics.

• Pre-Galvanised Finish
  Made from pre-galvanised mild steel, offering durability and corrosion resistance in interior structural environments.

Benefits

• Versatile Installation Options
  Can be nailed or welded depending on the construction requirements—perfect for both timber and steel framing integration.

• High Load Capacity
  Engineered to support substantial joist loads, including those used in long-span floors or composite timber construction.

• Customisable Design
  Other widths and heights are available as special orders, ensuring tailored solutions for non-standard joist sizes.

• Meets Structural Design Requirements
  Supports code-compliant construction when used with the correct fasteners and installation practices.

Applications

• Timber-to-timber engineered floor joist support

• I-joist hanger for residential or commercial floor systems

• Hybrid timber-steel framing (weld-on applications)

• Sloped or skewed framing with engineered timber joists

Installation Notes

• Use all specified fasteners. Ensure the timber header can accommodate all nails or screws required.

• Web stiffeners are mandatory when installing I-joists in HB hangers.

• In welded applications, uplift values do not apply. Always take special care when welding galvanised materials (ventilation and prep required).

Important Notes

• Always refer to Simpson Strong-Tie technical data sheets for design values, fixing patterns, and load adjustment factors for sloped or skewed installation.

• Special sizes and configurations available—contact Simpson Strong-Tie for ordering custom widths or heights.
