COLORSTEEL colours

FlaxPodCharcoal by day, deeper in the shade.

FlaxPod is a strong, earthy charcoal that NZ Steel says is neither a true black nor a standard grey. It's one of the favourites NZ Steel names, in Classic and Low Gloss, and there's a separate textured FlaxPod Matte. It reflects 21% of the sun's heat, so it's a warm roof.

Why does FlaxPod change through the day?

NZ Steel says FlaxPod reads more charcoal in daylight and deeper in shade, and that warm timber, rusted metal and stone bring out its undertones. The same roof can look grey at midday and close to black on a slope facing away from the sun.

So a small brochure chip is a poor guide. You need a full sample sheet, seen in sun and shade.

How to judge a FlaxPod sample

  1. Start in the sun

    Lean it against your sunniest wall, at ground level, and look at it from the street.

  2. Move it into shade

    Put it on the shady side of the house and look again. This is where FlaxPod goes deepest.

  3. Add your materials

    Hold it beside your cladding, joinery and any timber or stone. NZ Steel suggests comparing Ironsand and Ebony samples too.

  4. Choose the finish

    Classic has the usual COLORSTEEL sheen, Low Gloss has less, and FlaxPod Matte is textured with an ultra-low gloss.

  5. Check the quote

    It should name COLORSTEEL FlaxPod, the finish, MAXAM or ALTIMATE, and include the warranty.

Heat figures, coast and geothermal

NZ Steel gives FlaxPod a TSR of 21% and an LRV of 7%, without saying which finish that pair is for. If the exact figure matters to your design, ask your roofer to check.

FlaxPod comes in MAXAM for most of the country and ALTIMATE for the harshest coastal sites. Close to the sea or near geothermal activity, get the roofer to confirm the product and warranty with NZ Steel for your address.

Where we'd start

If you want a dark roof that feels natural rather than stark, FlaxPod in Classic is where we'd start, with Ebony as the bolder option. We're independent and have no link to New Zealand Steel. Once you've picked, we can pass the job to one checked local roofer.

Questions

Straight answers.

FlaxPod or FlaxPod Matte?
Same colour family, different surface. FlaxPod Matte is textured with an ultra-low gloss and reflects 20% against standard FlaxPod's 21%. NZ Steel says there's no texture match if a Matte roof is ever overpainted.
FlaxPod or Ironsand?
NZ Steel steers you to Ironsand for a stronger brown-charcoal and FlaxPod for a softer, earthier warmth. On its figures Ironsand reflects a little more heat (TSR 25% against 21%).
