HHB/GB/HGB Beam and Purlin Hangers


This series of beam and purlin hangers may be used for wood to wood or wood to steel applications. Precision forming provides dimensional accuracy and helps ensure proper bearing area and connection.

Material: See Top Flange Hangers – Glulam Beam table.

Finish: HHB, GB, HGB, all saddle hangers and all welded sloped and special hangers—Simpson Strong-Tie® gray paint. May be ordered hot-dip galvanized; specify HDG.


  • Use specified fasteners. See General Notes.
  • HHB, GB and HGB may be used for weld-on applications. The minimum required weld to the top flanges is 3/16″ x 2″ fillet weld to each side of each top flange tab. Distribute the weld equally on both top flanges. Welding cancels the top and face nailing requirements. Consult the code for special considerations when welding galvanized steel. The area should be well-ventilated. See welding information. Weld on applications produce the maximum allowable load listed. Uplift loads do not apply to welded applications.
  • Ledgers must be evaluated for each application separately. Check TF dimension, nail length and nail location on ledger.


  • HHB – other widths are available; specify W dimension (the minimum W dimension is 2 1/2″).
  • Saddle hangers are made to order; add “D” to model (e.g. HHBD3); specify S (for saddle) dimension. They may be used for most conditions except at end wall locations, and are preferred for nailer applications.
  • The coating on special B hangers will depend on the manufacturing process used. Check with your Simpson representative for details. Hot-dipped galvanized available: specify HDG.
  • B dimensions may be increased on some models.
