Experience the Double-U® difference…

Spanline Home Additions offers a variety of exclusive roofing profiles for use across our projects.

Our exclusive Double-U® features high tensile Aluzinc® coated steel which provides you with outstanding strength and quality. In fact, the exclusive roof shape and design makes it the strongest and most rigid profile in the home additions industry.

The unique design features high ribs, which create a shadowing effect to reduce absorption and radiation of heat. The valleys allow for greater water runoff, and provide resistance to debris and build up. The panels interlock, ensuring a weatherproof seal in all conditions. All of these aspects combine to offer a rigid and strong profile with longer spans, meaning fewer supporting posts. This means you can make space make moments® Double-U® is also fully tested for cyclonic weather and fire conditions and is certified to withstand extreme weather conditions, such as hail and storms.

Double-U® is manufactured by Spanline here in Australia, so we know it’s a quality product. Spanline is Australian owned and operated, so not only are you buying a quality product; you’re helping to keep business local.

With a variety of colour options available in our high-gloss Colorweld® finish and three different grades, there’s a Double-U® product for every project! Double-U® looks great on a patio, pergola or verandah, or a carport or shelter, and seamlessly integrates with our Spanlites® to help keep the weather out whilst still letting the light in.
