WM/WMU/WP/WPU/WNP/HW/HWU

The WPU, HWU and HW series purlin hangers offer the greatest design flexibility and versatility.

Material: WNP/WPI/WPU - 7 ga. top flange, 12 ga. stirrup; HW - 3 ga. top flange, 11 ga. stirrup; HWU - 3 ga. top flange, 10 ga. stirrup.

Finish: Simpson gray paint; hot-dipped galvanized available: specify HDG.

Allowable Loads: For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.

Installation:

Hangers may be welded to steel headers with 3/16" for WPU/WNP/WP/WPI, and 1/4" for HW/HWU, by 1 1/2" fillet welds located at each end of the top flange. Weld-on applications produce maximum allowable load listed. See weld information. For uplift loads refer to T-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.
MID-WALL INSTALATION: Installed between blocks with duplex nails cast into grout with a minimum of one grouted course above and below the top flange and one #5 vertical rebar minimum 24" long in each adjacent cell.
TOP OF WALL INSTALLATION: Install on top of wall to a grouted beam with masonry screws.

Options: See Hanger Options for hanger modifications and associated load reductions.

Some model configurationsmay differ from those shown.
Contact Simpson for details.

Table

The table indicates the maximum allowable loads for WNP, WP, WPU, HW or HWU hanger used on wood nailers. Nailers are wood members attached to the top of a steel I-beam, concrete or masonry wall. This table also applies to sloped-seat hangers.

Uplift value for the HWU hanger is for depth ≤ 18". Refer to uplift values in table below for taller depths.
Attachment of nailer to supporting member is the responsibility of the Designer.

16d sinkers (0.148" dia. x 3 1/4" long) may be used where 10d commons are called out with no load reduction.
Uplift loads are based on Douglas Fir and have been increased 33% and 60% for wind or earthquake loading; no further increase allowed. Divide by 1.33 for normal loading like cantilever construction.
Minimum f'_m = 1500 psi. See Installation Notes.
NAILS: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long, 10dx1 1/2 = 0.148" dia. x 1 1/2" long. See other nail sizes and information.
