The PCZ/EPCZ Post Cap is designed for easy and fast installation for post-to-beam connections. The post and beam flanges are in-line with 90mm square post and 90mm beam. The PCZ/EPCZ Post Cap reduces the chance of the post splitting and eliminates nailing into end grain. 

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

k1 = 1.14

Lateral
k1 = 1.14

  1. Design Capacity is the lesser of (1) the Characteristic Capacity multiplied by the Australian Capacity Factor (φ), and applicable the k modification factors following AS 1720.1 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 0.85 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 Australia Joint Group JD4 per AS 1720.1 Table H2.4.
  5. Uplift loads do not apply to spliced conditions. Spliced conditions must be detailed by the Designer to transfer tension loads between spliced members by means other than the post cap.
  6. Structural composite timber columns have sides that show either the wide face or the edges of the timber strands/veneers. Values in the tables reflect installation into the wide face and do not allow for installation into the narrow face.
  7. Post and beam may consist of multiple members provided they are connected independently of the post cap fasteners.
