Chris got a spanline deck - once it went thru council, it happened quickly. Easy communication, the deck looks amazing, they also helped follow up a gutter problem that was not their fault at all. Highly recommend!

We have a very large north-facing deck that bakes in the summer sun and was not very usable. When it rained our front stairs became a waterfall.Jamie from Spanline designed and quoted for a roof to cover about half the deck. This allows winter sun to still get into the house but protects the stairs and front door from rain and gives us a great shaded space to use. He also designed in the option of being able to enclose the space with walls later if we want to.The work was done promptly and to a high standard by the local tradesman and there was no dispute when we changed a couple of details late in the design stage.We couldn't be happier with the result and highly recommend Spanline. Not the cheapest option but definitely worth it for the quality of materials and installation.

Absolutely love my little deck awning. The finish is perfect. Shahil and Scott were great communicators, easy to deal with and paid attention to detail! Great job guys. 👏
We recently had a first-storey awning installed by Jason and his team at Spanline Coffs Harbour. Our original area was small and the wooden deck had deteriorated. Jason came out and met with us and we talked through what we wanted to achieve with area. Jason gave us several patio design options to choose from as well as a variety of colours and materials for the flooring. Jason recommended the Spanline Double U roof sheet advising us it was low maintenance and had long spans so we wouldn't need as many posts. Once we'd agreed on design things moved pretty quickly. The builders were very professional and were really pleasant to deal with. They even roped off the build area to make sure our gardens and lawn areas were protected. When the finished they left the site clean and tidy. The build quality is top notch and the Double U roof and new decking blend perfectly like it has always been a part of our house. Jason and his team were great and very easy to deal with. We honestly could not be happier with our new outdoor area that we can now sit out on and enjoy the views. We highly recommend Spanline.

The science of Roll Form Beams

Local Spanline Franchises produce Roll Form Beams at their manufacturing facilities. The beams are manufactured in a range of sizes and rolled to length to accommodate different size spans and floor construction weights.


What makes roll form beams the perfect solution for durable flooring:

  1. Production Process: Roll form beams are produced by gradually bending a flat sheet of metal into the desired shape. The beams are typically very consistent in shape and size – important for applications that require precision. Roll forming is a highly efficient process that produces beams at a high speed, making it a cost-effective solution.
  2. High Strength: Roll forming can produce beams with high strength-to-weight ratios, making them ideal for supporting heavy loads in flooring systems. The Spanline Flooring System subfloor will take up to 500kgs/m2.
  3. Durability: Roll formed beams, especially those made from steel, are highly durable and resistant to various environmental factors such as moisture, termites, and fire. Your subfloor will withstand even the most extreme weather conditions without warping or cracking.
  4. Versatility: Roll forming can be used to produce a wide variety of beam shapes and sizes making it ideal for both residential and commercial purposes. This includes standard shapes like I-beams and C-channels, as well as custom profiles.
