Product Overview
WP38 Welded Top Flange Joist Hanger
The WP is designed to support joists on purlins or beams and may be used for wood-to-wood or wood-to-steel applications. This top-flange hanger offers exceptional flexibility and versatility with the ability to be skewed up to 84° and/or sloped to a maximum of 45°. The WP is an economical choice with a low installed cost requiring a small number of nails for maximum downloads.
Key Features
Highly 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
Material
Stirrup — 97 mil (12 ga.)
Finish
Simpson Strong-Tie gray paint. Some models available hot-dip galvanized; specify HDG. See Corrosion Information.
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.
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.
