WMU/WP/WPU/HW/HWU Purlin Hangers

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

Material

• WP/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 Strong-Tie^® gray paint. Hot-dip galvanized available; specify HDG.

Installation

• Hangers may be welded to steel headers with 3/16" for WPU/WP, 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 General Instructions for the Installer, note m for weld information. For uplift loads refer to technical bulletin Top-Flange Hangers Welded to Structural Steel Members (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.

Options

• See Hanger Options for hanger modifications and associated load reductions

Load Tables

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

Nailer Table

The table indicates the maximum allowable loads for 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.

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

1. 16d sinkers (0.148" dia. x 3 1/4" long) may be used where 10d commons are called out with no load reduction.
2. Uplift loads are based on DF/SP lumber and have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
3. Minimum f'_m = 1500 psi.
4. For hanger heights exceeding the joist height, the allowable load is 0.50 of the table load.
5. Nails: 16d = 0.162" dia. x 3 1/2" long, 10d = 0.148" dia. x 3" long, 10d x 1 1/2" = 0.148" dia. x 1 1/2" long.
