The BIGGER backyard event gazebo

The 3×4.5m pop up tent provides an additional 4.52 coverage that sometimes makes all the difference.

Expanding from the 9m2 coverage from a 3x3m gazebo to a 13.5m2 sheltered area makes the 3×4.5m gazebo the perfect size when your event space isn’t endless. We’ve found that our 3×4.5m pop up tents fit best in backyards for parties as well as for the well set up camper looking for bigger protection from the elements.

Built for safety
(Bonus points for style)

  •   Oversized footplates for safe anchoring on all surfaces
  •   High strength hexagonal aluminium frame
  •   Heavy-weight connecting joints
  •   Canopy attached at 14 points

We also finish our frames and canopy with an air of refinement to help make your event a complete success. The smooth, brushed aluminium on all heavy duty gazebo frame parts provide both form and function – it both looks great and ensures long-term smooth operation.

The Altegra elite canopy material is undoubtedly a stand-out feature that all our customers love. It’s a pliable woven polyester that is finished to deliver serious protection.

Altegra event marquees set up on hard ground with 20kg steel leg weights to anchor safely.

5 reasons The Altegra 3x4.5m Heavy Duty is the right choice for events

Altegra 10-year heavy duty marquee manufacturer's warranty icon - genuine support from the brand who cares about your investment.

10 Year Genuine Manufacturer's Warranty

We are the designers, Australian manufacturers, we test for quality and we’re the suppliers of your 3×4.5m Heavy Duty gazebo. An advantage of maintaining control of all our products from design to delivery is that we have complete confidence and will guarantee that they perform as expected.

A “genuine” warranty is one where we genuinely care about the performance of our products and our customers who use them. Therefore, we back our 3×4.5m Heavy Duty gazebo extensively.

Altegra Heavy Duty Gazebos and Marquees are endowed with Cast Aluminium frame joints, the most robust solution without significant weight penalty.

Cast Aluminium frame joints

Our Cast Aluminium Frame joints are steadfast. The frame joint is the most functional component of the marquee, attaching the leg to the upper frame, roof truss to roof truss, and connecting the extendable legs. Substantial forces are imposed upon the marquee joints – therefore, there can be no compromise on strength.

Our heavy duty marquee joints are a harmony of considerable strength and tight tolerance, suppressing superficial movement throughout the marquee. We are proud to state that we have never had an aluminium marquee joint fail and that our 3×4.5m gazebos have incredible lifespans.

The Altegra Hexagonal Aluminium frame - the frame that Altegra pioneered which is used in our Pro Lite and Heavy Duty gazebos and marquees.

50mm Hexagonal Aluminium Marquee Frame

The heavy-gauge, 50mm Altegra hexagonal aluminium frame commands strength and longevity but retains easy handling. It’s in balancing these concerns where our hexagonal frame shade structures shine.

Our 50mm Heavy Duty marquee frame is a carefully engineered combination of aluminium extrusions. We’ve crafted each leg and truss of the marquee, optimising for strength and smooth operation while ensuring it remains portable. Rest assured, your Altegra 3×4.5m gazebo is an investment for many years of reliable outdoor shelter.

Australian Standards Section 238 compliant product icon - Altegra Heavy Duty marquees and Pro Lite gazebos are structurally engineered for event marquee safety.
Altegra 100km/h marquee wind rating icon - Heavy Duty marquees and Pro Lite Gazebos are engineered to withstand winds of over 100km/h.

Prescribed Temporary Structures Certificate of Compliance (Section 238)

By designing and manufacturing our Heavy Duty 3×4.5m gazebos using Australian safety regulations and our valued customer feedback as the baseline, we can deliver an exceptional product that exceeds expectations. Australia holds exceptionally high safety standards, which forms the backbone of all of the design of our Heavy Duty marquees. Ensuring public safety when using a gazebo at events is an absolute MUST.

Section 238 regulatory compliance is mandatory for public use of 3×4.5m gazebos in Australia. All our 3×4.5m Heavy Duty gazebos carry current structural computations from independent Australian engineers authenticating conformance with the Prescribed Temporary Structures requirements.

We designed and Manufactured this gazebo to Suit the rigours of high-demand use

Our Heavy Duty gazebos and marquees have been revised through 15 years of improvement to target reliability for frequent use. Our commercial marquee users put our pop-up tents through the heaviest use, therefore, are a valuable source of feedback for product revision and innovation. As a result, all components of our Heavy Duty range are professional grade.

The Hire and Rental Industry Association Australia – HRIA is the authority who advocate for the safe use of portable shade structures. Our recommendations for safe marquee use is based on the HRIA Marquee Weighting Guide and the HRIA Marquee Pegging Guide. Our HRIA customers are among the most frequent users, who expect that their heavy duty pop-up marquees deliver exceptional performance.
