Top-Flange Hangers for Solid Sawn Lumber

This product's information may differ depending on the category of use. You are currently viewing details related to Top-Flange Hangers for Solid Sawn Lumber.

The HWP is designed to support joists on purlins or beams in both wood and cold-formed steel construction. This top-flange hanger has enhanced uplift and is ideal for high-wind applications. The HWP offers design flexibility and versatility in supporting trusses off of wood or steel and can have a sloped and/or skewed seat up to 45°.

Key Features

  • Modifiable with alteration options including opened/closed top-flange and offset top-flange
  • Top flange may be sloped to a maximum of 35° to accommodate a sloped header
  • Features a solid one-piece top flange that provides extra stability in panelized roof applications


  • 7-gauge top flange and 12-gauge stirrup


  • Simpson Strong-Tie gray paint. Hot-dip galvanized available; contact Simpson Strong-Tie.



  • Use all specified fasteners.
  • The HWP may be used for weld-on applications. The minimum-size weld is a 1 1/2"-long fillet weld to each side of the top flange; weld size to match hanger material thickness. See General Instructions for the Installer, note k for weld information. Weld-on applications have the maximum allowable capacity listed. Uplift loads do not apply to this application.
  • Non-modified hangers can support joists sloped up to 1/4 :12 using table loads. For joists sloping between 1/4:12 and 3/4 :12 use 85% of the table loads. See technical bulletin Sloped Joist in Non-Sloped Hangers (T-C-SLOPEJST).
  • Web stiffeners are required for these hangers.
  • If joist is shorter than hanger by more than 1/2" use only 50% of the table loads.

Load Tables

See Top-Flange Hanger Tables.

See Hanger Options for hanger modifications, which may result in reduced loads.

The table indicates the maximum allowable loads for HWP hangers used on wood nailers. Nailers are wood members attached to the top of a steel I-beam, concrete or masonry wall.

Nailer Table

HWP Nailer Table
  1. Attachment of nailer to supporting member is the responsibility of the designer.
  2. Uplift loads are based on DF/SP lumber. For SPF/HF, use 0.86 x DF/SP uplift load. 

Various Header Applications

HWP Various Header Applications
  1. Code values are based on DF/SP header species.
  2. Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  3. For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.
  4. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connector.
