Why Make the Switch to Cliplock Steel Roofing?

Colorbond Steel has been tested and reworked for over 50 years in Australia’s most challenging environments. If you have a distinct vision for your home or commercial property, Cliplock (Klip-Lok) is strong, lightweight, customisable, easy to install, maintain, and thermally efficient all throughout the year.

Colorbond Cliplock Steel Roofing is more than just paint on steel. Manufactured in Australia to Australian Standards (AS1397 and AS/NZS 2728), you can expect more than premium aesthetics.

Whether you want an investment that will last a lifetime, are searching for coated steels, or just want a superior design for your industrial building, Cliplock 0.42 roofing sheets are an effective solution that exceeds performance standards. This blog will take you through style options, technical advantages, and why you should choose Colorbond over traditional metal roofing.

What is Cliplock 0.42 Steel Roofing?

Also known as Klip-Lok, Cliplock Steel Roofing is ideal for flat roof line designs. Along with supreme water tightness, a strong higher rib profile, and rising from flat pans into longitude fluting with long, straight lines for a clean finish, it is bound to make a bold statement for Australian homes. Let’s have a look at some of its features:

  • It has a Base Material Thickness (B.M.T) of 0.42.

  • The material is High Tensile Steel G550.

  • The roofing has an effective cover of 700mm in width per sheet.

  • Cliplock has a Rib Height of 42.5mm +/- 1mm, with a Roof Pitch of a minimum of 1 degree.


Using a concealed fixing system, Cliplock is suited to larger industrial or commercial buildings or low-pitched roof lines on residential buildings. Suitable for walling and roofing, these concealed fixing clips are excellent for water tightness, so you don’t need to worry about leaks during the rainy season.

Benefits of Choosing Steel Roofing

What are the benefits of choosing Colorbond Steel Roofing for your home or commercial property? There are many reasons to go for the Cliplock design.

1. Longevity and Durability

Longevity and durability of steel roofing

Used in all sorts of ways for old and new homes, Colorbond roofing adds character but is also incredibly durable and a worthwhile investment for the entire family. Colorbond has five layers of protection.

  • The steel base. Meeting manufacturing standards will always adhere to the required grade and strength. 
  • The base is coated in BlueScope industry-leading metallic coating. This incorporates an Activate Technology to provide enhanced corrosion resistance.
  • Next, a thin pre-treatment layer is applied to support the adhesion of further coatings. A corrosion-inhibitive primer is baked onto the surface.
  • Finally, a top coat is developed. This is an exterior grade paint baked on to provide resistance to chipping, flaking, and blistering. The finish retains its look for longer. It’s also important to note that Activate Technology is unavailable for Colorbond Intramax Steel or Colorbond steel products with a galvanised steel substrate.

2. Resistance to Corrosion and rust

Strong and secure for many property types, Cliplock Steel roofing sheets are an excellent choice as they don’t rust or corrode.

With a 30-year roofing warranty guarantee from BlueScope® Steel for weathering and corrosion due to natural elements, there is a 20-year warranty against paint flaking or chipping. Colorbond typically lasts at least 30 years but can last up to 70 with proper care and maintenance.

3. Thermal efficiency

When designing a project, it’s important to consider thermal reflective materials and the climate in which you are building.

Cliplock Steel Roofing has thermal comfort with Thermatech® Solar Reflective technology, which optimises solar reflective features. Reflecting more of the sun’s heat on hot, sunny days increases your family’s comfort without constantly relying on air conditioning.

Likewise, Colorbond is lightweight and insulated, preventing heat from transferring into your home at night. Steel has a low thermal mass, so it cools faster once the sun has gone down! Compared to pre-painted steel (regular PPGL), Colorbond with Thermatech can cut annual energy usage by up to 20%.

Note: Thermatech technology is available in all colours except Night Sky.

4. Sustainable and fire protection

All Colorbond Steel–including Cliplock roofing–is a recyclable material, with the steel itself being 100% recyclable. Creating a more sustainable, circular economy, this roofing is a resource that lasts. No losses are necessary due to the downgrading of recyclable material.

As steel has magnetic properties, it can easily be separated for recycling, and the economic value of steel results in a high recovery rate of all steel waste. This saves money for construction projects,

After its life cycle, Colorbond is processed for scraps and then recycled.

Cliplock Steel Roofing is also fire-resistant. If you intend to construct your commercial or residential property in a bushfire-prone area, Colorbond steel protects you as it is incombustible.

5. Design Versatility

Cherish your home for years to come. One of the most attractive things about Colorbond roof sheets is that you can design them however you want. Team up the dramatic tones with timber and stone.

Whether your goal is hardwood or aluminium window frames and doors, poured concrete sections or reclaimed timber decks surrounded by flora, design options are endless. Colorbond has a contemporary palette for roofing and walling profiles, so it’s perfect for an upgrade. Choose Woodland Grey® for a classic finish and make your property look expensive.

6. Range of Steel Colours Available

Have a specific colour in mind? With 28 colours in the range, Cliplock steel transforms roof aesthetics.

If you envy pale tones, Colorbond BlueScope Steel shades are naturally inspired and light, and they are equally at home for contemporary or heritage buildings. Tones such as Dover White®, Surfmist®, Classic Cream®, Evening Haze®, Southerly®, Shale Grey®, and Dune® are the ideal base for a dramatic contrast of colour and material, perfect for a seaside home.

Aiming for more earthy mid-tones? Blending beautifully with any landscape, colours such as Basalt®, Bluegum®, Windspray®, Gully®, Wallaby®, and Pale Eucalypt® are warm, welcoming, and distinctively Australian.

For bolder, darker tones such as Manor Red®, Iron Stone®, Monument®, Woodland Grey®, Jaspar®, Night Sky®, Deep Ocean®, and Cottage Green® suit all steel profiles and complement many design palettes. Accentuate new architecture and create a premium, design-driven feeling for urban and rural properties.

7. Premium Finishes

Planning a new garage door with a classic finish or dark walling, or do mid-tones inspire you? With a Matt roofing material that is soft in appearance yet durable, this diffuses light for a textured finish and a modern, sophisticated look. 

Choose Windspray® roofing and gutters in a Classic finish or a Surfmist® Matt finish for a roof that anchors colour and material palette for both interior and exterior.

Pairing Matt with a Classic finish creates an elegant look for any home style, and Cliplock Roofing Systems does the job for homes and businesses.

8. Weather Resistance

Worried about howling winds, torrential rain, or a hailstorm? Colorbond steel can handle anything, including wind pressure. Although these would put normal roofing to the test with costly repairs and frustrating maintenance, Colorbond is a high-performing solution throughout all seasons. 

  • Hot and sunny climates. Posing difficulties for roofing, high temperatures, and direct UV radiation from the sun can accelerate the aging and degeneration of roofing materials, such as fading over time.
  • Cold and snow climates. For rural Victorian areas, Cliplock roofing systems can endure snowfall and handle the weight of snow, which can damage your structure. 
  • Coastal climates. Colorbond can withstand strong winds, exposure to seawater, and places vulnerable to tropical storms. Able to resist corrosive effects from seawater, Colorbond can offer additional reinforcement, protection, and durability for your home.
  • Heavy rainfall climates. Colorbond can handle heavy precipitation, preventing water leakage with waterproofing properties and superior drainage systems. 
  • Hail-prone climates. Hailstorms can seriously harm roofs, resulting in leaks and a weakened structure, but Colorbond can withstand different-sized hail stones, reduce damage, and increase the lifespan of your roof.

Cliplock Steel Roofing – Tips for Installation

Let’s look at the best tips for Cliplock steel roofing installation and what will support the process.

  1. Hire qualified installers. Whether you’re dealing with a fascia gutter, standard roofing fasteners, or Cliplock steel roofing, your installers must be trained in Colorbond installation methods and the correct flashing, fixing, and sealing techniques.
  2. Use recommended accessories for Colorbond roofing, such as ridge cappings, valleys, flashings, and other accessories required as per the manufacturers’ instructions.
  3. Always follow manufacturer guidelines. This can include precise information on installation techniques, suggested fasteners, sealants, and important considerations.
  4. Allow for thermal expansion. As a Cliplock steel roof stretches and shrinks due to temperature changes, installers need to allow room for expansion by creating gaps and adhering to the manufacturer’s instructions. This can prevent tension or harm to the roof.
