FAQ

What is corten steel, and why is it ideal for garden use?

Corten steel is a weathering steel that forms a stable, rust-like patina that protects the material from corrosion. It’s durable, low-maintenance, and develops a natural look perfect for NZ landscapes.

Will the rust stain my patio or garden surface?

When corten steel begins to weather, some rust runoff may occur. We recommend placing planters on gravel, grass, or concrete during the initial rusting stage. After the patina stabilizes, staining is minimal if at all.

Do the planters come assembled?

All our planters are flat-packed for easy delivery and include stainless steel fixings. Assembly typically takes minutes with tools supplied.

Can I use corten steel planters for vegetables and herbs?

Yes! Corten steel is safe for growing edibles. You can also use internal lining recommendations for added peace of mind.

How long does corten steel take to develop its patina?

Initial patina development usually starts within a few days and matures over several weeks. The process depends on local moisture and weather conditions.

Can I customise the size or design?

Absolutely. We cater to trade and custom orders — contact us with your specifications, and we’ll provide a custom quote.
