WP/HWP/HWPH/WMU Plated Truss Top-Flange Hangers

WP/HWP/HWPH/WMU

On This Page

The WP hangers offer design flexibility and versatility supporting trusses off of wood or steel. WMU hangers are designed for use on standard 8" grouted masonry block wall construction.

Material

  • WP/HWP — 7-gauge top flange and 12-gauge stirrup; HWPH — 3-gauge top flange and 7-gauge stirrup

Finish

  • Simpson Strong-Tie gray paint; hot-dip galvanized available: specify HDG

Installation

  • Use all specified fasteners.
  • The WP 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.
  • 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.

Options

  • For skewed trusses using the WP hanger, order the Type B stirrup for proper bearing
  • For 4x2 trusses, the ANP nail pattern may be ordered with WP hangers, which will relocate the joist nails to the top and bottom chords
