Combining striking aesthetics, proven performance and durability for Australian conditions, COLORBOND® steel offers a practical and versatile solution for homes designed to last.

Whether you're building a new home, planning a renovation or refreshing outdoor spaces, the materials you choose today can influence how your home looks, performs and feels for years to come.
 

A trusted Australian choice

Since its introduction in 1966, COLORBOND® steel has become a familiar feature of Australia's residential landscape. Manufactured in Australia and designed specifically for Australian conditions, it has earned its place as Australia's favourite roofing material.

From contemporary architectural homes to suburban renovations and rural retreats, COLORBOND® steel is used across a wide variety of applications, including roofing, walling, fencing, sheds, patios and garages.

When you choose COLORBOND® steel, you're choosing a product backed by decades of Australian manufacturing experience and innovation.
 

Colour that brings a home together

Selecting exterior colours is one of the most important decisions in the home design process. The COLORBOND® steel palette makes it easier to create a cohesive and considered look across your home's exterior.

The range includes 22 colours in the Classic finish and six colours in the premium Matt finish, with tones inspired by Australia's natural environment. Whether your style leans towards coastal, urban, modern or traditional, the palette offers flexibility to complement a wide range of architectural styles.

Many manufacturers, including Dulux, Stegbar and Wideline, offer products matched to COLORBOND® steel colours, making it easy to create a coordinated look across your home's exterior.

Designed and tested for Australian conditions

Australian homes are exposed to a diverse range of environmental conditions, from intense UV and high temperatures to heavy rainfall, humidity and coastal salt exposure.

To help ensure COLORBOND® steel performs where it matters most, it undergoes extensive testing programs that assess corrosion resistance, durability, outdoor exposure and compatibility with common building products and applications.

Helping create more comfortable homes

The roof plays an important role in the overall comfort of a home.

Twenty-one colours in the COLORBOND® steel Classic range, along with all six Matt colours, feature Thermatech® solar reflectance technology. Designed to reflect more of the sun's heat on hot sunny days, Thermatech® technology may reduce cooling energy consumption depending on factors such as roof colour, insulation levels and overall home design¹.

For homeowners seeking comfort and efficiency, roof colour selection can make a meaningful difference.
 

Supporting sustainable building choices

Sustainability considerations continue to influence the way Australians design and build homes.

All COLORBOND® steel contains recycled content, while the steel itself is 100% recyclable. In some applications, steel products can also be reused without requiring reprocessing, helping conserve energy and resources.

For homeowners looking to incorporate sustainable materials into their projects, these attributes can be an important consideration.
 

Easy-to-maintain

Modern life is busy enough without adding unnecessary maintenance requirements.

COLORBOND® steel is designed to be easy to care for, helping maintain its appearance over time with minimal upkeep. In many situations, regularly washing exposed surfaces with clean, fresh water can help maintain the product and prolong its service life.

Maintenance is typically not required for surfaces that are naturally washed by rainwater, such as roofing.

This makes it an attractive choice for homeowners wanting a practical building material that supports long-term performance.

Supporting bushfire design requirements

For homes located in bushfire-prone areas, material selection plays a critical role.

Roofing, walling, gutters and downpipes manufactured from COLORBOND® steel may form part of a compliant construction system for bushfire-prone areas, including areas with a BAL-FZ rating (Bushfire Attack Level – Flame Zone), as defined by AS 3959:2018.

Homeowners should always seek professional advice to ensure compliance with relevant building regulations and project requirements.

When building a home that's designed to last, what's beneath the surface matters. Genuine COLORBOND® steel is backed by decades of Australian innovation and engineering, helping deliver the durability, performance and appearance homeowners have trusted for generations. It's one of the reasons COLORBOND® steel continues to be chosen for homes across Australia, from contemporary new builds to renovation projects inspired by shows like The Block.
