Colorsteel Metal Cladding: The Modern Steel Wall
Steel is not just for roofs anymore. Colorsteel metal cladding has become one of the most popular ways to finish the walls of a modern New Zealand home — crisp lines, a huge colour range, and the same tough, low-fuss performance that makes steel such a good roofing material. This guide covers how metal cladding works, vertical versus horizontal, the common profiles, the architectural look everyone is after, and how to pair cladding with your roof so the whole house reads as one.
What metal cladding is
Metal cladding is long-run steel sheet — the same family of products used on roofs — run down or across the walls of a building as its outer skin. On homes it is almost always Colorsteel: steel coil with a zinc-aluminium protective coating and a baked-on paint finish, rolled into one of several profiles. It gives you a weathertight, durable, low-maintenance wall that looks sharp and modern.
It can clad a whole house or just feature sections — a lot of designers mix cladding materials, using steel on part of the home alongside timber, brick or plaster to create contrast and interest.
Vertical vs horizontal
Which way you run the cladding changes the whole feel of a building, and it is one of the first decisions to make.
Vertical cladding draws the eye upward and makes a building feel taller and more striking — it is the look you see on a lot of sharp, contemporary builds and barn-style homes. Horizontal cladding feels calmer, wider and more grounded, and can echo the lines of traditional weatherboard. Neither is "better" — it is about the look you want and how it suits the shape of the house. Both are fully weathertight when detailed and installed correctly.
- Vertical: taller, bolder, modern and barn-style looks
- Horizontal: wider, calmer, echoes classic weatherboard lines
- Mixing both on one home is a common way to zone different areas
Common cladding profiles
The profile is the shape pressed into the sheet, and it sets the character of the wall. There is a profile for almost every look.
- Corrugate: the classic rounded wave, run vertically for that rural-meets-modern feel
- Trapezoidal / rib profiles: squarer, bolder ribs for a strong contemporary line
- Interlocking plank and tray profiles: flat, crisp panels with clean shadow lines for a sleek architectural look
- Weatherboard-look steel: profiles designed to mimic traditional timber boards with far less upkeep
The modern architectural look
A big part of why metal cladding has taken off is simply how it looks. Clean, continuous lines, deep matte colours, and sharp shadow detail give a home a confident, current feel that is hard to get any other way. Darker charcoals and blacks are hugely popular on contemporary builds, while softer greys and heritage tones suit homes that want to feel a little warmer or more rural.
Because the roof and the walls can be the same material and colour family, you can wrap a whole form in one skin for a bold, monolithic look — or deliberately contrast cladding against timber and glass. It is a flexible, designer-friendly material, which is exactly why architects reach for it.
Durability and performance
Metal cladding brings the same toughness that makes steel such a good roof. It stands up to our weather, does not rot or warp like timber can, resists insects, and the baked paint finish holds its colour well. It is lightweight, which keeps things simple structurally, and it is non-combustible — a genuine plus.
As with roofing, the coating grade has to suit your environment. Closer to the coast or in harsher conditions, you step up to a more corrosion-resistant grade. Warranties on the steel and the paint finish are real but vary by product, colour and location, so we will confirm the exact position for whatever we recommend rather than quoting a number that might not apply to your site.
- Tough against wind, rain and sun
- Does not rot, warp or attract borer like timber
- Lightweight and non-combustible
- Low maintenance — an occasional wash in sheltered spots
- Coating grade matched to how exposed your site is
The things to weigh up
To be straight with you, metal cladding is not the answer for every home. The right coating spec matters in coastal and industrial areas, and like all metal it can dent under a solid impact. Good detailing around windows, corners and junctions is critical — that is where a cheap or rushed install shows up as leaks or scruffy lines down the track. The material rewards doing it properly.
It is also a design choice as much as a practical one. Bold cladding looks fantastic on the right house; it is worth getting the profile, colour and orientation right for your home rather than just copying what is on the house down the road.
Pairing cladding with your roof
Where metal cladding really sings is when it is considered alongside the roof. Running the same Colorsteel colour across roof and walls gives a seamless, modern, wrapped look. Or you can pick a complementary pairing — a dark roof over lighter cladding, or steel walls under a contrasting roof profile.
Because we do both roofing and cladding, we can help you get this right from the start so the two work together rather than clashing. Matching coating grades, colours and detailing across the whole exterior is the kind of thing that is easy when one team is thinking about the whole house.
Cladding on new builds — and getting a quote
Metal cladding is a natural fit for new builds and architectural projects, where it can be designed in from the start alongside the roof for a cohesive result. We work on new builds and architectural homes regularly and are happy to work in with your builder, designer or architect on the roofing and cladding together.
What a cladding job costs depends on the area to be clad, the profile and colour you choose, the coating grade for your site, access, and how much detailing is involved around windows and corners — so we quote properly rather than guessing. Paul Makuch Roofing has been doing this across the Waikato since 1997, we are a Licensed Building Practitioner and fully insured, based in Pirongia and serving Hamilton, Cambridge, Te Awamutu and beyond.

Common questions
What is the difference between metal roofing and metal cladding?
They are the same family of long-run steel products — cladding is simply run down or across the walls instead of over the roof. Using the same Colorsteel on both lets you wrap a home in one seamless, modern skin.
Should I run my cladding vertically or horizontally?
Vertical cladding makes a building feel taller and bolder and suits modern or barn-style homes; horizontal feels wider and calmer and echoes classic weatherboard. Both are fully weathertight when installed properly — it comes down to the look you want.
Is Colorsteel cladding low maintenance?
Yes. It does not rot, warp or attract borer, and the baked paint finish holds its colour well. In sheltered spots that rain does not naturally rinse, an occasional wash keeps it looking fresh — otherwise there is very little to do.
Can you do my roof and cladding together?
Yes, and it is the best way to get a cohesive result. Because we handle both, we can match colours, coating grades and detailing across the whole exterior so the roof and walls work together. Call Paul on 07 847 9785 to talk it through.
