Great job done in a relatively short time, wasn’t cheap, but worth it. We’re now enjoying our new large and modern veranda daily. Jamie the builder was friendly and hardworking.

We recently had a roof fitted over our deck area and we couldn't be happier. Jamie was fantastic to work with, very professional and I felt very assured with the choice of design and colour we chose. The product itself is of very good quality, super sleek design. Aaron did an absolutely fantastic job installing the roof. He was professional, friendly, prompt and an absolute pleasure to work with. I couldn't recommend Spanline Port Macquarie highly enough. Thank you team.

We are very happy to have chosen Spanline to replace our back verandah. They have supplied a very good product & we can't fault the workmanship. The two guys on the job were pleasant to have around. John & Kerry Presland, Kew, NSW.
Thanks Spanline ACT for making our "vision" from 6 years ago into a reality! My garden studio/sunroom was completed by Spanline recently in June 2026 after initial contact in January 2026. It took us awhile to get our plans into place because we were disappointed with other companies for not being helpful and we also lack the expert knowledge. Overall: Spanline made everything easy for us from start to finish. Everyone we encountered with Spanline are wonderful and have great customer service skills! We would like to acknowledge everyone involved in the project: Peter - was our "go-to" from start to finish. Peter showed us the showroom, did the visits, the planning, approvals and the blueprint. Peter goes above and beyond by being approachable/contactable if we have concerns by connecting us with the appropriate persons for the job. Peter explains technicalities in simpler terms which is extremely helpful for us being ESL and having no industry knowledge. Thanks for making everything easy for us Peter! Bede - did all the transport of the materials and rubbish, everything was handled with care. Bede just like the other Spanline guys is approachable and friendly. Sebastian - the project manager or the expert problem solver, there were issues but Sebastian always have a solution for everything. Thank you for being attentive to our questions and concerns. Janno - did most of the construction of the project, Janno has remarkable and professional handiwork. Janno listens to our concerns and questions. Janno is respectful by always checking with us first before doing the installations e.g location of windows or doors. There had been leaks in our sunroom, Janno has been coming over to assess and repair until we are leak-free. Aside from being highly competent and professional at the job, Janno is warm and friendly to our neighbors, our family and pets while working on-site. Thanks Janno! Claudia - thanks for the calls and for updating with what is happening with the projects. We will miss your warm and friendly voice!

A big thank you to Jamie for his great advice and professional service throughout the process and to Josh for his outstanding workmanship and attention to detail. The whole experience was smooth from start to finish, and the finished patio looks fantastic. I highly recommend Spanline Mid Coast to anyone looking for a quality outdoor addition.

Adam was very professional and skilful. He was very friendly and informed us of any issues. A couple of days he was late but made up for it. The bad wind was a set back but Adam handled it very safety and professionally.

So far I have just had a visit, assessment and quote from Scott Basman from Spanline, for alterations to my home. I found Scott very informative, attentive, and has plenty of ideas, and gives sound reasons for his recommendations. I would certainly invite his opinion and quote for quality work.

We recently had an opening roof and verandah extension done by Spanline and are very happy with the result. We have a Solar passive house and wanted an addition which was in keeping with our needs. Getting the winter sun into our house is very important to us and Spanline were very respectful of our needs. There were a few hiccups along the way during the build but Spanline were always quick to resolve any issues that came up. We cannot praise Dean our tradie onsite highly enough. He was always very professional and considerate of our needs. Thank you Spanline team.

Jamie gave great advice in suggesting that I could have new Insulated Roof Panels installed to the existing posts as they were sturdy, and it would save me money. The new panels look so good and will be much cooler in summer months, and also much quieter when it pours raining. Aaron was fantastic with the installation, from arrival to completion he was courteous. He cleaned up and removed rubbish after each stage of the work. Aaron is a very experienced builder. I am extremely happy with the finished roofing and Spanline was easy to communicate with, from the quoting process with Jamie to completion of the installation.

A big thank you to Nick, Frank, Jeff and the team at Spanline Illawarra. We had a room built onto the back of our house that has doubled our living area and we couldn’t be happier with the end result. It would be fair to say they exceeded our expectations. Frank came out and listened to what we wanted and with his experience in the industry provided suggestions on further improvements and design. Frank took care of all the approvals and this gave us pieces of mind. Nick came back to us with additional options and we are so glad we incorporated these. Nick kept us in the loop while the build was underway the communication was great. The build was completed in a very short timeframe, nothing was too much trouble and our home was kept clean and tidy. We have no hesitation recommending these guys we are so happy we used Spanline Illawarra.

After a considerable wait and evaluating the competition, I decided to put my faith in Spanline. Aaron was assigned to my project and encountered some challenges on the day, notably the weather. Despite this, he remained composed, showed patience and did not complain. He made a few visits and fitting off some flashing to complete the project. I’m very pleased with the results and attention to detail and only wish I didn’t wait so long to get my carport done

We had our entertainment area fully enclosed and could not be happier with the result. These guys are true professionals who clearly take great pride in their work. From the initial design right through to manufacturing and installation, they communicated brilliantly, arrived when they said they would, and went the extra mile to make sure everything was perfect and we were completely satisfied. The quality of the finished product is excellent.I can’t recommend them highly enough — they made the whole process smooth and stress-free. Highly recommended!

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.
