About Steel Line
Steel-Line has been making doors in Australia since the 1980s, with factories in Perth and Brisbane and a dealer network across the country. Their ranges, from the Smartline roller door to the Streetscape sectional, are built from Colorbond steel for Australian conditions, made to a spec that Perth builders have come to trust over many years.
As an authorised Steel-Line dealer and installer, our team knows the full range, and we’re not tied to one product, so when we recommend a Steel-Line door it’s because it genuinely suits your opening, your site and your budget. We supply, install and service Steel-Line doors right across the Perth area for businesses, builders and strata managers.

Why Choose Steel Line
There’s a reason builders and business owners keep asking us for Steel-Line. Here’s what sets the doors apart, whatever the job requires.
Design Your Steel Line Door
Download the Steel-Line brochures below to see the full range of profiles, colours and finishes, then send us a photo of the opening and tell us how the door will be used. We’ll come back with the options that suit the site, explain how each one opens and what headroom it needs, then arrange a free measure so the sizing and detail are spot on.
Our Steel Line Service In Perth
Knowing the product is one thing; fitting it properly is what makes it last. Our installers handle the whole job, from a free measure and a fixed quote to a clean, professional install and ongoing service. We fit Steel-Line doors on business premises right across Perth, we put the same effort into a single replacement as a full new build, and we clean up and leave the site tidy. We’ve stripped out enough cheap imports that warped in their first summer to know what a properly made door is worth.
Most Steel-Line jobs start with the opening, not the catalogue. We check the headroom, side room, wind exposure and how many times a day the door will cycle, then match the range and the motor to suit, so the door you choose for its looks also holds up to the work.
