HWPH High-Wind Purlin Heavy Hanger

Top-Flange Hangers for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Top-Flange Hangers for Plated Truss. You can also view product information related to the categories of: Top-Flange Hangers for Solid Sawn Lumber, Top-Flange Hangers for Engineered Wood

The HWPH is designed to support joists on purlins or beams in both wood and cold-formed steel construction. This heavy top-flange hanger has enhanced uplift and is ideal for high-wind applications. The HWPH offers design flexibility and versatility that provides very high uplifts and down loads.

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
  • Available with a sloped and/or skewed seat up to 45°


  • 3-gauge top flange and 7-gauge stirrup


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


  • Use all specified fasteners.
  • H dimensions are sized to account for normal joist shrinkage. W dimensions are for dressed timber widths.
  • The HWPH 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. For additional load information, refer to technical bulletin Top-Flange Hangers Welded to Structural Steel Members (T-C-WELDUPLFT).
  • Hangers can support multi-ply carried members; the individual members must be secured together to work as a single unit before installation into the hanger.
  • 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).
  • If joist is shorter than hanger by more than 1/2" use only 50% of the table loads.
  • Web stiffeners are required for these hangers when using engineered wood.
  • For attaching to multi-ply headers in engineered wood applications, refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-MPLYHEADR).


  • See General Notes for Hanger Options.
  • Some model configurations may differ from those shown. Contact Simpson Strong-Tie for details.
  • Hangers with a skew greater than 15° may have all the joist nails on the outside angle.
  • For skewed condition, top flange width can increase up to 18". Contact Simpson Strong-Tie for specific application.
  • When using in solid sawn or engineered wood applications, specify the slope up or down in degrees from the horizontal plane and/or the skew right or left in degrees from the perpendicular vertical plane. Specify whether low side, high side or center of joist will be flush with the top of the header.
  • The HWPH may have a sloped and/or skewed seat up to 45°. See Modifications and Associated Load Reductions table below for reduction associated with modifications.
  • HWPH can be skewed up to 84°
  • The top flange of the HWPH may be offset and/or sloped down up to 35°. The top flange may also be opened/closed up to 30°. See Modifications and Associated Load Reductions table below.
  • HWPH models are available in Type A (bevel-cut) for solid sawn and engineered wood applications. Contact Simpson Strong-Tie when ordering.
  • Hangers with a skew greater than 15° may have all the joist nails on the outside angle.
  • For hanger modification options, see Modifications and Associated Load Reductions table below.
  • For concrete and masonry applications, refer to the WMU top-flange hanger.

Load Tables

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

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

Nailer Table

HWPH 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

HWPH Various Header Applications
  1. Uplift loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Joist dimensions do not include truss plate thickness.
  3. 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.
