Determine the Installation Area of Roof
There are 4 different roof zones for tilt leg installation: Internal Zone, Intermediate Zone, Edge Zone and Corner Zone.
Please see diagrams and steps below to define area of each zone.
Step 1. Determine building height (h), width (b) and length (d).
Step 2. Choose the lowest value between "h", "b x 0.2" and "d x 0.2".
Step 3. The lowest value on Step 2, equates to a.

Verify Purlin Properties of Building
Please verify purlin properties of building, which could affect the interface spacing. Tilt legs spacing on in the
certification letter is based on steel purlin G450 1.5 mm thick or 35 mm Timber F7 (Pine). For example, if the steel purlin
is less than 1.5 mm thick, the corresponding reduction factor of interface spacing will be applied. Please refer generic
notes 6-7 for details.
