The BA Top Fix I-Joist Hanger is designed to be used where a heavy load/connector is required. It is cost-effective and 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.   

Please check Corrosion Information if it is suitable for your application.

  1. Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the NZ Strength Reduction Factor (φ), and applicable the k modification factors following NZS 3603 and (2) the Serviceability Capacity which is the load at 3.2mm joint slip. Design Capacity is the minimum of test data and structural joint calculation.
  2. The Capacity Factor (φ) is 0.8 for nails and screws for structural joints in a Category 1 application. Reduce tabulated values where other Category applications govern.
  3. Duration of Load Factor (k1) is as shown. Reduce Duration of Load Factor where applicable. Capacities may not be increased.
  4. Timber species for joint design is seasoned Radiata Pine, which is New Zealand Joint Group J5 per NZS 3603 Table 4.1.
  5. The Design Capacities may be multiplied by 1.3 when 75mm x 3.75mm face nails are used.
