IronsandNamed for the west coast. Check your distance from it.

Ironsand is a deep brown-charcoal that NZ Steel says draws on the rugged tones of New Zealand's west coast. It's one of the favourites NZ Steel names, in Classic and Low Gloss. A TSR of 25% means it reflects a quarter of the sun's heat, like most dark roofs.

How brown is Ironsand in real light?

The brown is what separates it from the cooler greys. NZ Steel suggests comparing physical samples beside your cladding and joinery. Beside cedar, brick or earthy weatherboards it usually looks settled; beside a cool white it can read closer to plain charcoal.

A west coast colour on a west coast house

If you actually live on the west coast, the colour is the easy part. NZ Steel's coastal categories reach further inland on that side: Very Severe runs from 50 m to 500 m from the coast, and Extremely Severe covers the first 50 m from the high-water line. MAXAM isn't recommended in Extremely Severe, where ALTIMATE, the marine-grade aluminium product, takes over.

Away from the sea, MAXAM covers most of the country. Near geothermal activity, NZ Steel asks you to talk to COLORSTEEL or your supplier before choosing.

How to settle on Ironsand

  1. Get samples of all three

    Ironsand, FlaxPod and Ebony side by side make the brown easy to spot.

  2. Look outdoors, from the ground

    Prop them against a wall in morning and late-day light. NZ Steel says screens show colour differently, so don't decide from a photo.

  3. Check for colour rules

    Some rural zones control roof colour. Queenstown Lakes District Council's colour guide lists Ironsand as usually appropriate in its rural zones.

  4. Get it in writing

    Ask for COLORSTEEL Ironsand by name in the quote, with the product, the finish and a copy of the warranty.

Questions

Straight answers.

Is Ironsand brown or grey?
A bit of both. NZ Steel calls it a deep brown-charcoal, and how brown it looks depends on the light and what's beside it. For less brown, compare it with FlaxPod.
