Simpson Strong-Tie HB3.56/28 - 3-1/2" x 28 Top Flange I-Joist Hanger

The HB is a top-flange hanger designed to carry medium to high loads for solid sawn and engineered wood applications. This heavy beam hanger features a full-height joist flange that captures the top chord of the joist to prevent rotation. With its one-piece design, the HB provides a cost-effective solution compared to welded hangers.

Key Features

• Efficient design that provides a cost-effective options for high-load applications
• Available for special order to accommodate sloped and/or skewed members

Finish

• Galvanized. May be ordered hot-dip galvanized; specify HDG.

Installation

• Use all specified fasteners; see General Notes and nailer table.
• May be used for weld-on applications. The minimum size weld is a 2"-long fillet weld to each side of each top flange; weld size to match hanger material thickness. Distribute the weld equally on both top flanges. Welding eliminates the top and face nailing requirements. Consult the code for special considerations when welding galvanized steel. The area should be well-ventilated; see General Instructions for the Installer, note k for weld information. Weld-on applications produce the maximum allowable download listed. For additional load information, refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-WELDUPLFT).
• Web stiffeners are required for I-joists.
• Ledgers must be evaluated for each application separately. Check TF dimension, nail length and nail location on ledger.
• 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).
• Bevel-cut the carried member for skewed applications.

Options

• Other widths are available; specify W dimension (the minimum W dimension is 1 9/16").
• For modified hangers, fastener quantity listed in tables may need to increase depending on joist size, skew and slope.
• Hangers may be modified for slopes and/or skews up to 45º. The top flanges may be sloped as much as 35º and may be open or closed up to 30º.
