* For the complete range of panel spans versus load, refer to Bondor New Zealand's Design Guide
* Spans are indicative only and apply to wall and roof profiles using 0.6 BMT steel, specific site conditions need to be calculated by an Engineer.
* For canopies and snow load use AS1170.3.
* For wind speed direction refer to code AS1170.2 regions A6 and A7 and W, by default use 1.00Kpa, note wind pressure depends on life of building
* 0.50kPa loading takes account of fire load.

* Roof pitches will vary depending on site conditions, loads, purpose, configuration, snow loading and span requirements.
* Buildings designed with widely spaced purlins and portal frames may require a frame pitch increase of 1.5%.
* Under the building code, insulated panel used as a cladding is an Alternative Solution. In a roofing application, Bondor New Zealand panel satisfies the requirements of the NZBC External Moisture – Clause E2, when correctly specified and installed with flashings, which direct the flow of water away from the building envelope.
