Product Overview
BA7.12/9.5 Top Flange Joist Hanger
The BA hanger is a cost-effective hanger used for structural composite lumber and high-capacity I-joists. When used with I-joists, the positive-angle nailing at the joist seat allows the hanger to be used without web stiffeners.
The HB hanger is also available with higher capacity for structural composite lumber and heavier I-joist applications.
Material
See top-flange hanger tables.
For modified hangers, gauge may increase from that specified for non-modified hangers. Hanger configurations, height and fastener quantity may increase from the tables depending on joist size, skew and slope.
Finish
BA and HB — galvanized; all saddle hangers and all welded sloped and special hangers — Simpson Strong-Tie gray paint
BA and HB may be ordered hot-dip galvanized; specify HDG
Installation
Use all specified fasteners; see General Notes and nailer table.
BA and HB 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 cancels 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 uplift loads refer to technical bulletin Top-Flange Hanger Reductions for Multiple-Ply Headers (T-C-WELDUPLFT).
HB hanger requires the use of web stiffeners. BA min. nailing does not require web stiffeners. BA max. nailing requires the use of web stiffeners.
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").
The coating on special BA hangers will depend on the manufacturing process used. Check with your Simpson Strong-Tie representative for details. Hot-dip galvanized available: specify HDG.
For modified hangers, fastener quantity may increase from the tables depending on joist size, skew and slope. All modified hangers are 12 ga.
The BA and HB hangers may be modified for slopes and/or skews up to 45º. The top flanges may be sloped up to 35º and may be open or closed up to 30º. See Modifications and Associated Load Reductions below.
