Flexiroof is engineered using materials chosen for performance (6061-T6 aluminium, 99% UVA + UVB blocking polycarbonate sheet, and 316 stainless steel fasteners) to make it suitable across all of New Zealand’s coastal, alpine and urban environments.
The Flexiroof structure is constructed from high-tensile 6061-T6 structural-grade aluminium. Aluminium is an exceptional construction material: it is light, strong, corrosion-resistant, long-lasting and infinitely recyclable.
Aluminium has a powerful strength to weight ratio, meaning it’s strong while also very light. Having an aluminium structure means Flexiroof puts minimal weight stress on your house and deck, so both your shelter and your existing structures stand the test of time.
The Flexiroof system uses 6061-T6 aluminium. Aluminium tempered to T6 has very high tensile strength, making Flexiroof aluminium extremely strong and resilient. Aluminium has minimal deflection, meaning it is very rigid and doesn’t sag under load in the same way as other construction materials. Flexiroof is rated for up to 1.5 kPa snow loads (150kg of load per m²), making it well suited to handling snow loads in New Zealand's alpine climates.
Aluminium is naturally corrosion resistant, which means that Flexiroof won’t rust, even in coastal areas. The Flexiroof system uses a 6106 alloy, a structural-grade alloy known for its ability to withstand salt spray and harsh coastal air. This makes Flexiroof suitable across all of New Zealand, meaning we can guarantee all Flexiroof shelters with our 10 year warranty no matter where in the country you are.
The aluminium used in our Flexiroof structure is extruded locally in New Zealand by McKechnie Aluminium, New Zealand’s only recycled aluminium extruder. McKechnie is Toitū carbon reduce certified; they recycle 100% of waste aluminium, which is contributed directly back into their extrusions, including Flexiroof.
Flexiroof uses Eurolite 3™ polycarbonate roofing; lightweight, incredibly strong, and designed for New Zealand conditions. UV-stabilised for long-term performance, with a subtle grey tint that softens light while maintaining clarity.
Up to 250 times stronger than glass and significantly lighter, Flexiroof reduces the load on your home while delivering exceptional durability.
UV-protected to maintain strength and clarity in both direct and reflected sunlight; designed to handle New Zealand’s demanding environment.
Blocks 99.9% of UVA and UVB rays with noticeable heat reduction, creating a more comfortable outdoor space year-round.
Working with ThermaAssist™ technology, this eliminates noise and reduces stress on the structure.
The engineered sheet profile naturally channels water away from joins and into the integrated gutter system.
The Flexiroof system uses 316 stainless steel fasteners, the highest standard for outdoor construction.
316 stainless steel (also known as ‘surgical steel’) has high resistance to chlorides, giving it superior corrosion resistance compared to standard 304 grade stainless steel. Using 316 stainless steel fasteners means Flexiroof stays strong and enduring in coastal environments.
316 stainless steel is solid all the way through. It remains bright and clean over time, and has the flexibility to move slightly with temperature changes without cracking.
