Clean COLORBOND™ steel
Clean COLORBOND™ steel has been at the forefront of steel technology and product innovation for years. Clean COLORBOND™ steel continues to set new performance benchmarks. Through constant innovation, Clean COLORBOND™ steel is now Improved. The latest enhancement is an innovated pre-painted coating technology that is proven to keep your building cooler and looking newer for longer. Not to be used closer than 5km from breaking surf(beach)
Clean COLORBOND™ Ultra  
If you want long lasting attractive roof material that offers you excellent protection against severe environments, Clean COLORBOND™ Ultra steel is the only choice.
From severe coastal environments to severe industrial environments, Clean COLORBOND™ Ultra steel is one of the most effective building materials to combat these harsh environments, where there may be a smell of salt or salt spray in the air, approximately 100 to 200m from breaking surf. Similarly, the effects of industrial emissions (fumes and/or particulate fall out) are typically lessened 100 to 200m from the source.
Its coating consists of 55% aluminium, 43.5% Zinc and 1.5% silicone and comes with a AZ200 coating which means that for every square meter of steel that there is a minimum of 200 grams of zinc/aluminium coating.
With the higher metallic coating mass and unique protective paint system, Clean COLORBOND™ Ultra steel is one of the most effective building materials available for harsh environments.
Its coating consists of 55% aluminium, 43.5% Zinc and 1.5% silicone and was developed after extensive research into improving the traditional performance of galvanised iron.
Product Description and Features
Roof sheeting made from ZINCALUME® steel is available in a range of profiles. The zinc/aluminium alloy coating on ZINCALUME® steel imparts corrosion resistance of up to four times the life of galvanised steel.
One of the most thermally efficient roofing materials available today

Heat Stop is an innovative development in polycarbonate translucent roof sheeting. This product effectively eliminates 60% of the radiated heat of the sun, resulting in a cool shaded environment.
Heat Stop is a polycarbonate profiled extrusion, manufactured in South Africa, which has a co-extruded layer of UV stabilised surface protection on the weather side. Microscopic reflective particles are incorporated in the core material which create the silver colour and the reflective qualities of the product.
If an application for a translucent roof sheet or skylight requires a minimum heat build-up under the natural light panel – MODEK offers a polycarbonate solution. It should be remembered, however, that a lower level of light
transmission is achieved with Heat Stop. The appropriate surface area of translucent roof sheets must therefore be used to achieve the required interior light levels.
Heat Stop offers the following properties:
• All the excellent physical properties of polycarbonate.
• UV surface protection on weather side.
• Exciting new colour – silver.
• 20 % light transmission.
• It is available in 1 mm and 1.25 mm profiles: IBR Corrugated Nurib Grecca
