JB/LB/B/BA/HHB Joist, Beam, and Purlin Hangers
LEAD TIME: may be up to 3 Days
The BA hanger is a cost effective hanger featuring min/max joist nailing option. Min Nailing featuring Positive Angle Nailing targets moderate load conditions whereas the Max Nailing generates capacities for higher loads. The unique two level embossment provides added stiffness to the top flange.
The newly improved B hanger offers wide versatility with enhanced load capacities.
See Top Flange Hanger tables. See Hanger Options for hanger modifications, which may result in reduced loads.
Material: See Top Flange Hanger tables.
Finish: BA, JB, LB, and B—Galvanized; HHB - all saddle hangers and all welded sloped and special hangers - Simpson Strong-Tie® gray paint. BA, LB, B and HHB may be ordered hot-dip galvanized, specify HDG.
Use specified fasteners. See General Notes and nailer table.
LB, BA, B and HHB may be welded to steel headers with weld size to match material thickness (approximate thickness shown). The minimum required weld to the top flanges is 1/8" x 2" (1/8" x 1 1/2" for LB) fillet weld to each side of each top flange tab for 14 and 12 gauge and 3/16" x 2" fillet weld to each side of each top flange tab for 7 gauge.
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 welding information). Weld on applications produce the maximum allowable down load listed. For uplift loads refer to T-WELDUPLFT.
Ledgers must be evaluated for each application separately.
Check TF dimension, nail length and nail location on ledger.
Refer to T-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).
Options: B and HHB
Other widths are available; specify W dimension (the minimum W dimension is 1 9/16" for B and 3 1/4" for HHB).
See Hanger Options. BA, JB and LB hangers cannot be modified. Use LBV as an alternative for the JB/LB.
