About Steel-Line
Steel-Line has been manufacturing garage doors in Australia for over 45 years. Founded as a family business and headquartered in Brisbane with manufacturing plants in QLD, NSW and VIC, Steel-Line is the country's largest privately-owned garage door manufacturer. Their key competitive advantage is the direct-from-factory model — Steel-Line supplies installers like Limitless without a wholesale layer in between, which keeps lead times short and pricing sharp.
The brand is best known for the Fortex sectional door (a flush, contemporary panel that's become extremely popular on modern Toowoomba builds) and a deep custom panel program that lets us match almost any architect's drawing. Steel-Line uses Australian BlueScope Colorbond steel across the entire range.
Why Limitless is an Authorised Steel-Line Dealer
Steel-Line operates a tightly controlled dealer network — they only sell direct to authorised installers, never through retail. As an authorised Steel-Line dealer, Limitless receives factory pricing, priority production scheduling on custom panel orders and direct technical support from the Brisbane plant. Every door we install is genuine factory product with the full Steel-Line manufacturer warranty backed by the OEM, not a third-party reseller.
- 100% genuine factory parts
- Manufacturer-backed warranty cover
- Factory-trained installers
- Direct supplier pricing

Steel-Line — Frequently Asked Questions
What's the difference between Steel-Line and Steeline?
Two completely different companies despite the similar name. Steel-Line (with the hyphen) is a Brisbane-based garage door manufacturer. Steeline (no hyphen) is a national network of independent steel and roofing distributors that also supplies garage doors. We deal with both — the products are not interchangeable.
How long does a Steel-Line custom door take to make?
Standard Fortex and Heritage doors typically arrive at our workshop within 10-15 working days of order. Custom panel builds in non-standard sizes, mixed materials or special colours generally take 4-6 weeks from final drawing approval.
Is Steel-Line made in Australia?
Yes. Steel-Line manufactures in Brisbane, Sydney and Melbourne using Australian BlueScope Colorbond steel. The bulk of Limitless installs come out of the Brisbane plant, which keeps freight time to Toowoomba under 48 hours.
What warranty does a Steel-Line door carry?
Steel-Line provides a 7 year structural warranty on sectional and roller door curtains, and 12 months on hardware in domestic applications. Commercial warranties are quoted per project. Limitless administers warranty claims directly with the Steel-Line factory on your behalf.
Can you fit a Steel-Line Fortex door to an existing opening?
Yes — that's our most common Fortex install. We measure the existing structural opening, order the panel kit cut to size from Steel-Line, and fit it to your existing brickwork or timber jamb. Most retrofits are a half-day on site.
