Exploring material options and Colorsteel^® finishes for Roller Doors

Why material choice matters for Roller Doors

Roller Doors are a traditional style of garage door. However, because they offer strength and smooth operation with minimal maintenance requirements, they remain one of the most popular options in both residential and commercial settings. Roller Doors are particularly ideal for garages with limited headroom, especially compared to more modern Sectional Garage Doors, which are more suited to contemporary homes with ample overhead space.

You’ll typically find Roller Doors made from steel or aluminium. The right material depends on your environment, budget and style preferences. Below, we break down the pros and cons of each option.

Common Roller Garage Door materials compared

Steel Garage Doors

Steel Garage Doors are strong and long-lasting. They provide solid against the elements and are impact-resistant However, if the powdercoating is scratched or not maintained, can become an issue, especially in coastal  areas.

Aluminium Garage Doors

The key features of Aluminium Roller Doors make them an appealing option for homeowners. They are lightweight, more resistant to rust compared to steel (which makes them ideal in coastal or humid settings) and they’re also quieter and require less maintenance. On the downside, they can be more expensive than steel and more prone to dents.

Composite or custom materials

Composite Doors, often made from an aluminium core with a fibreglass or vinyl exterior, are known for being low-maintenance and corrosion-resistant. They can mimic the look of timber without the upkeep. While durable and stylish, they tend to be the most expensive option.

What is Colorsteel®?

New Zealand-made Colorsteel® is a pre-painted steel product that is designed and tested to withstand our harsh weather conditions.

It begins with Zincalume® coated steel, offering a longer lifespan than traditional galvanised steel. This base is then pre-treated, primed and painted using a system that improves corrosion resistance, UV protection and scratch durability.
