Product Description

The Simpson HB312 Top Flange Hanger for Heavy Beam 3x12 is a professional-grade structural connector from Simpson designed to support medium to high loads in both solid sawn and engineered wood heavy beam applications. Its top flange configuration and one-piece steel construction make it a dependable choice for top chord bearing installations where rotation prevention and consistent load transfer are essential.

Key Features

  • Top Flange Design - The full-height joist flange captures the top chord of the joist, preventing rotation under load and helping maintain structural alignment throughout the life of the installation.
  • Heavy Beam Compatibility - Sized specifically for 3x12 heavy beam applications, this hanger works with both solid sawn lumber and engineered wood, giving builders flexibility across a range of structural framing projects.
  • One-Piece Construction - The single-piece design eliminates the complexity and cost associated with welded hangers, streamlining installation while delivering reliable performance for medium to high load demands.
  • Galvanized Finish - The standard galvanized finish provides corrosion resistance suited to demanding job site conditions, with a hot-dip galvanized option available for applications requiring enhanced protection.
  • American-Made Quality - Produced in the United States, the HB312 reflects the manufacturing standards that structural professionals rely on for consistent, code-compatible framing connections.

Why This Product

  • Purpose-Built for Heavy Beam Work - Unlike general-purpose hangers, the HB312 is engineered specifically for heavy beam connections in solid sawn and engineered wood applications, making it a precise fit for demanding structural framing rather than a compromise solution.
  • Rotation Prevention Where It Counts - The full-height joist flange actively captures the top chord, reducing the risk of joist rotation during and after load transfer - a critical performance factor in top chord bearing installations.
  • Cost-Effective Alternative to Welded Hangers - The one-piece steel construction delivers structural performance for medium to high load applications without the added expense or lead time that welded connector assemblies typically require.
  • Finish Options for Different Exposure Conditions - With both a standard galvanized finish and a hot-dip galvanized option available, the HB312 can be matched to the corrosion-resistance requirements of the specific installation environment.
