Why Choose Galvanised Over Corten?

While corten steel develops a rustic rust patina, galvanised steel maintains its bright metallic finish and offers the longest-lasting corrosion protection of any steel finish. Choose galvanised when you want a clean, modern look or when installing in coastal or high-moisture environments where maximum corrosion resistance is essential.

Frequently Asked Questions

How long does galvanised steel last outdoors?
Galvanised steel is the longest-lasting steel finish available. In most Australian conditions it will outlast both mild and weathering (corten) steel, often lasting 20+ years with minimal maintenance.

Can I connect Ridgidline to Flexline?
Yes, Ridgidline and Flexline panels can be connected using Straightcurve joining hardware, allowing you to combine straight and curved sections in the same garden design.

Is it easy to install?
Yes. Ridgidline is designed for easy DIY installation on soft ground, hard surfaces and even concrete. Smaller heights simply peg into the ground, while taller panels use pins for stability.

Will the galvanised finish rust?
The hot-dip galvanised coating is specifically designed to resist rust and corrosion. It is particularly well suited to coastal and humid environments where untreated steel would corrode quickly.
