What to Consider When Finishing Metalwork Near the WA Coast
Westforge Works · Reviewed 2026-08-21
Short answer
Salt exposure. Coastal air accelerates corrosion, so metalwork in Rockingham, Baldivis, Secret Harbour, Mandurah and similar locations needs thorough preparation, a coating system chosen for salt exposure, and attention to edges, welds and fixings.
Why coastal exposure is harder on metalwork
Airborne salt settles on surfaces and holds moisture against them. Corrosion starts wherever the coating is thinnest or the surface was not properly prepared — typically edges, welds, bolt holes and fixings.
What helps
A few practical decisions make a large difference to service life near the coast.
- Thorough preparation before any coating is applied
- A coating system selected for salt exposure rather than appearance alone
- Attention to edges, welds and fixings during coating
- Suitable fixings and hardware, not just a coated frame
- Periodic washdown and inspection of exposed metalwork
Gates and property metalwork
Coastal driveway gates and property metalwork are common in our primary service areas. The gate itself, its frame, hardware and any automation should all be considered together when choosing a finish.
Limitations worth noting
- No finish is maintenance-free in a coastal environment.
- Coating selection depends on the item, its exposure and its expected life.
