Steeline is a national network of independent steel and roofing distributors that also supplies a complete garage door range. We supply and install Steeline roller and sectional doors across Toowoomba and the Darling Downs — particularly when the garage door needs to colour-match an existing Steeline shed or roof.

Steeline (no hyphen — different company to Steel-Line) is an Australian-owned cooperative of independent steel and roofing distributors with branches across the country. Founded in 1985, Steeline started as a roofing and steel framing supplier and expanded into the garage door category to give its trade customers a single supplier for the shed, the roof and the door.
Because Steeline is a distributor network rather than a manufacturer, the garage doors are made by partner factories to Steeline's specification and supplied through the local Steeline branch. The big advantage is colour matching — a Steeline garage door is guaranteed to come from the exact same Colorbond batch as a Steeline shed or roof, which matters a lot on rural builds where everything needs to match.
Limitless is a recognised installer for the Steeline Toowoomba branch. That means we install Steeline-supplied garage doors on rural shed packages and re-roofs, with full warranty cover passed through from the Steeline supplier and the underlying door manufacturer. The benefit to the customer is single-supplier accountability — one invoice, one warranty contact, perfect Colorbond colour match across the door, the shed and the roof.
The models we install most often across Toowoomba, the Darling Downs and SE Queensland.
Standard residential / shed roller, Colorbond
From $1,750 supplied & installed
Steeline's everyday roller door. Full Colorbond colour palette, smooth-running drum and bracket assembly. Most common spec on Steeline rural shed packages.
Heavy-duty roller for sheds and workshops
From $2,650 supplied & installed
Heavier curtain and reinforced barrel for industrial sheds, workshops and machinery shed openings up to 6m wide.
Residential sectional, full Colorbond
From $2,300 supplied & installed
Steeline-supplied sectional door — typically used when a customer wants a sectional residential look with a guaranteed colour match to existing Steeline cladding or roofing.
Door + matching cladding from same Colorbond batch
Quoted on plan
Combined supply of garage door and matching shed/roof cladding from one Colorbond production batch. The right call when an exact colour match across all elements is important.
Like-for-like roller curtain replacement
Quoted on inspection
Replacement Colorbond curtain colour-matched to the original Steeline supply. We measure, order through the Steeline branch and fit on site.
Oversize / non-standard industrial doors
Quoted on plan
Steeline can spec doors well beyond the standard residential range — wide-span shed openings, custom shed kits and rural machinery sheds. We measure and quote from your shed drawings.
Steeline is almost always the right answer when the customer is doing a Steeline shed package — particularly across rural properties in the Lockyer Valley, Western Downs, Cambooya, Greenmount and Vale View. Single-supplier accountability and a guaranteed Colorbond colour match across the door, the shed walls and the roof is something the bigger national door brands genuinely can't offer. For pure standalone garage door work without a shed or re-roof in the mix, B&D, Steel-Line or Gliderol are usually a better fit.

No — completely different companies despite the very similar name. Steeline (no hyphen) is a national distributor network of independent steel and roofing branches. Steel-Line (with the hyphen) is a Brisbane-based garage door manufacturer. We're an authorised supplier for both, and the products are not interchangeable.
When you want a guaranteed Colorbond colour match across a new shed, re-roof or extension. Steeline garage doors are supplied from the same Colorbond batch as Steeline cladding and roofing, so on a rural shed package the door, the walls and the roof come out perfectly matched. For pure garage door work without those other elements, B&D, Steel-Line or Gliderol are usually a better choice.
Yes. We service every Steeline-branded door regardless of who originally supplied or installed it. The underlying mechanism is standard so we carry compatible springs, drums and openers in stock.
Steeline doors carry a 7 year structural warranty on the curtain or panel and 12 months on hardware in domestic applications. Warranty is administered through the Steeline branch that originally supplied the door, with Limitless acting as the installer service agent.
Yes. Steeline carries both roller and sectional doors. Sectional spec is less common in Steeline supply (most customers go for a roller as part of a shed package) but the option is there if you need it.
