Simpson Strong-Tie WP211.25-2 - Welded Top-Flange Joist Hanger for 1-1/2" x 11-1/4" Double Top Flange Ijoist 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

Finish

• Simpson Strong-Tie^® gray paint. Some models available hot-dip galvanized; specify HDG. See Corrosion Information.

Installation

• Use all specified fasteners.
• H dimensions are sized to account for normal joist shrinkage. W dimensions are for dressed timber widths.
• 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. For additional load information, refer to technical bulletin Top-Flange Hangers Welded to Structural Steel Members (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.
• 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).
• If joist is shorter than hanger by more than 1/2" use only 50% of the table loads.
• Web stiffeners are required for these hangers when using engineered wood.
• For attaching to multi-ply headers in engineered wood applications, refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-MPLYHEADR).

Options

• See General Notes for Hanger Options.
• Some model configurations may differ from those shown. Contact Simpson Strong-Tie for details. For special order WP hangers, see technical bulletin Special-Order Worksheet - WP Hanger (T-C-WP-WS).
• WP models are available in Type A (bevel-cut) or Type B (square-cut) style for solid sawn and engineered wood applications.
• Hangers with a skew greater than 15° may have all the joist nails on the outside angle.
• For skewed condition, top flange width can increase up to 18". Contact Simpson Strong-Tie for specific application.
• When using in solid sawn or engineered wood applications, 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.
• Uplift loads are not available for open/closed TF, TF sloped and offset options.
• The WP may have a sloped and/or skewed seat up to 45°. The WP may be skewed up to 84°.
• The top flange of the WP may be offset and/or sloped down up to 35°. The top flange may also be opened/closed up to 30°. See Modifications and Associated Load Reductions table below.
• For hanger modification options, see Modifications and Associated Load Reductions table below.
• 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.

Ridge Hanger

• Top flange may be sloped to a maximum of 35° to accommodate a ridge. Specify angle of the slope. Reduce allowable load using straight-line interpolation. Specify H/L/C flush when ordering sloped top flange.

Saddle Hanger (WPD)

• WPD saddle hanger allowable loads are WP loads for each stirrup. Saddle hangers on stud walls do not achieve catalog loads.
• Recommended S dimension is 1/16" oversized for carrying members 2 1/2" wide and less or 1/8" oversized for greater than 2 1/2" wide.
