Custom steel structures for schools


A metal roof or COLA (covered outdoor learning area) structure is a cost-effective, steel shade solution for schools needing waterproof cover to their sports courts, playgrounds and quadrangles. Options of the traditional gable or curved style mean your COLA structure can effortlessly fit in with the existing architecture.

Size: [W] 6m to 50m typically, up to 100m. [L] 6m to 150m typically, but not limited.
Typical Applications: Schools, shopping centres, recreational areas, car parks, bus shelters, quadrangles, playground equipment, sports courts.
Key Design Advantages: Robust, cost effective, excellent vandal resistance.
Coverage Options: Metal, options for skylights and acoustic paneling.





A Cantilever structure provides shade right where you want it!

The columns are in a line to one side of the area and the supporting rafters span out over the area, pinpointing the shade where it’s needed most. When you need shade but can’t have columns at the extremities, this is the obvious choice.

Hundreds of Greenline Cantilever structures have been installed in shopping centre car parks across Australia, because it is the most practical, stylish and long-lasting option. These are most often used in car parks because Australian Standards (AS2890.1) restricts post placement.

Size: [W] 4m to 15m typically, up to 25m. [L] 6m to 50m typically, but not limited.
Typical Applications: Car parks, pools, awnings against buildings, walkways, courtyards, restaurants.
Key Design Advantages: Posts offset to maximise shade + accessibility.
Coverage Options: PVC, shade fabric or metal.

ballina fair shade umbrella conic structure


The high centre peak of the Conic shade structure provides a striking aesthetic feature, creating a unique ambience unmatched by any other structure.

Also known as a pavilion shape, or even just a ‘circus tent’, large areas can be covered with minimal columns, meaning you have better scope to use your space.

The low perimeter gives good all day cover, and the high centre point creates a spacious feel without compromising weather protection.

Size: 4m to 50m typically, but not limited.
Typical Applications: Schools, pool areas, quadrangles, playgrounds.
Key Design Advantages: Maximum weather protection with fantastic style.
Coverage Options: PVC, shade fabric.

I have used Greenline for a number of years now as I have always found them to provide excellent customer service, great quality and reliability. Our most recent project was a covered walkway to provide extra shelter for our students.

From day one, the walkway was such a big hit, with so many students using it that we actually had to provide extra staff in the area for additional student supervision. Thank you Greenline.
