ENGINEERING NOTES
ENGINEERING NOTES
1.	 The Span Tables are to be used for external non-habitable applications only.
2.	 Design Wind Class is to be determined in accordance with AS 4055:2021 - Wind loads for housing.
3.	 Any side of new roofing with more than 50% of clear area from ground to sheeting blocked is 
considered  to be an enclosing wall.
4.	 Maximum post height is to be 3m.
5.	 Beams are to be stitch-screwed at 300mm centres maximum.
6.	 Allowable mid-span deflection limits adopted for Delta BeamsTM are:
Wind Loads - span / 125
Maintenance Loads - span / 150
Permanent Loads - span / 300
7.	 Allowable lateral deflection limit adopted for the posts is height / 150
8.	 Maintenance load of 1.4kN has been allowed for.
9.	 No gable infill is allowed.
GENERAL NOTES
The information contained in this Engineering & Construction Manual is specifically designed to suit the 
range of freestanding and attached Delta Panels™ Awnings, Patios & Carports Kits which have been 
engineered for Insulated Roofs. 
Delta Panels™ Awnings, Patios & Carports Kits are considered to be a freestanding structure unless it’s 
attached to an existing structure for at least 50% of its shortest side.
The information contained in this Engineering manual relates specifically to products supplied by Delta 
Panels Pty Ltd™. Any products not approved by Delta Panels Pty Ltd™ will void Engineering Approvals 
and Warranties expressed or implied.
All assembly, connection and installation procedures must comply with the Delta Panels™ standards as 
set out in the Engineering & Construction Manual
CONCRETE/FOOTINGS
For any connections to an existing concrete slab, it is the Builder/Owner’s responsibility to ensure that the 
slab is structurally adequate to support the additional load, including consideration of any uplift forces.
-   Concrete strength must be a minimum of N25 in accordance with AS 1379-2007.
-   The slab must cover the full width of the roof and reinforced with SL72 mesh or greater.
-   Any Piers are to be founded in natural firm to stiff clay with a minimum allowable bearing capacity of  
    100kPa. Contact a Geotechnical Engineer for advice to establish that these conditions can be met.
-  If fixing to a concrete slab, the slab is to be continuous over the area under the roof and the slab  
    dimensions shall be equal to or greater than the overall roof width and length.
