What Are the Best Shed Materials for Perth’s Climate?
Perth’s hot summers, high UV, coastal corrosion (C3/C4 zones), and easterlies demand the right steel and paint system. The industry standard for premium garages is Colorbond or Zincalume cladding over a galvanised steel frame. Here’s how they compare for WA conditions.
Colorbond vs Zincalume — Which Is Better for WA Conditions?
| Feature | Colorbond Steel | Zincalume Steel |
|---|---|---|
| Coating system | Painted, baked-on finish over AZ coating | Aluminium-Zinc (AZ) coating, no colour |
| UV resistance (Perth) | Excellent. Keeps colour and gloss longer | Very good, but reflective silver only |
| Corrosion near coast (C3/C4) | Very good with correct grade; consider Ultra where applicable | Good; can show tea-staining near surf coasts |
| Heat island/thermal | Cooler colours with high solar reflectance available | Reflective but hotter under radiant load without insulation |
| Cost | Higher | Lower |
| Best use | Homes, coastal, premium finish | Rural, budget, inland |
Added 2024 WA wind-rating compliance notes: For Perth and coastal WA, specify the wind region (A or B), Terrain Category (often TC2), topographic modifier, and consider AS 4312 corrosion category to select standard or “Ultra” finishes.
