WP3520-2 Double Top Flange I-Joist Hanger
The WP, HWP and HWPH series purlin hangers offer the greatest design flexibility and versatility. WMUs are designed for use on standard 8"-grouted masonry block wall construction.
The HWP and HWPH high-wind purlin hangers have enhanced uplift. They are ideal for high-wind applications.
(Top flange /stirrup): WP — 7 /12 gauge; HWP — 7 /12 gauge; HWPH — 3 / 7 gauge
Simpson Strong-Tie Gray Paint
Use all specified fasteners.
H dimensions are sized to account for normal joist shrinkage. W dimensions are for dressed timber widths.
WP/HWP/HWPH hangers may be welded to steel headers with a minimum 1 1/2"-long fillet weld on each side of the top flange to the header. Weld sizes: WP = 3/16", HWP = 3/16", HWPH = 1/4" (see General Instructions for the Installer, note k for welding information). Weld-on applications achieve maximum allowable download. Uplift loads do not apply to this application. For uplift loads, refer to technical bulletin 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.
If joist is shorter than hanger by more than 1/2", then use only 50% of the table loads.
See General Notes for Hanger Options.
Refer to technical bulletin Sloped Joist in Non-Sloped Hangers (T-C-SLOPEJST) for information regarding load reductions on selected hangers which can be used without modification to support joists which have shallow slopes (≤3/4:12).
Some model configurations may differ from those shown. Contact Simpson Strong-Tie for details.
WP models are available in Type A (bevel-cut) or Type B (square-cut) style. Contact Simpson Strong-Tie when ordering.
Hangers with a skew greater than 15° may have all the joist nails on the outside angle.
Skewed HWs have face nails and require a minimum header depth of 3 1/2".
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 (see illustration).
Uplift loads are not available for open/closed TF, TF sloped and offset options.
Ridge Hanger (only available for WP)
Top flange may be sloped to a maximum of 35° to accommodate a ridge (see illustration). Specify angle of the slope. Reduce allowable load using straight-line interpolation. See Open/Closed example.
