Heavy Duty 3x4.5m Gazebo Overview

Our Heavy Duty 3x4.5m gazebo has long been a favourite 13.5m2 for high-demand users and those who seek top quality. The Heavy Duty aluminium frame is our no-holds-barred robust folding gazebo frame, engineered to outlast while maintaining portability. Extensive integrity and extensive protection from the elements.

We developed our most integral 3×4.5m pop up gazebo to maintain important portability and ease of deployment. The burly frame is constructed using lightweight aluminium extrusions that resist torsional stresses and suppress frame movement. Every component is built to deliver integrity and to last. Our Lifetime Warranty ensures confidence.

We continue the premium quality approach with our Elite Canopy. High-quality PVC lined Polyester is double stitched with high-tensile thread, is double layered at key friction points, and gets anchored to your gazebo at numerous locations.

Altegra 3x4.5m Gazebos for events use with white UPF50+ canopy.

The bigger backyard event gazebo. An additional 4.5m2 coverage from your 3x4.5m pop up tent can make an impact.

Expanding to a 13.5m2 sheltered area makes the 3x4.5m gazebo the perfect size when your event space is tight. We've found that our 3x4.5m pop up tents fit best in backyards for parties, weddings, and events.

The added coverage area also makes for the perfect additional movement space for the well set up camper who's looking for more extended protection from the elements than the traditional 3x3m camping gazebo.

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

Built for Commercial Event safety

We 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 looks great and ensures smooth long-term operation.

To cap it off, the Altegra elite canopy material is undoubtedly a stand-out feature that all our customers love. The high-quality, woven polyester is pliable and delivers serious weather protection.

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

Altegra Lifetime Warranty icon - leading marquee manufacturer's warranties

Genuine Lifetime Manufacturer's Warranty

We design, manufacture, test for quality, and are the suppliers of your Heavy Duty 3x4.5m 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 3x4.5m Heavy Duty gazebo extensively.

Altegra heavy duty gazebo and heavy duty marquee cast aluminium joint image

Cast Aluminium Frame Joints

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

Our heavy duty gazebo joints harmonise high strength and tight tolerance, helping suppress superficial movement throughout the marquee. We are proud to state that we have never had an aluminium marquee joint fail and that our Heavy Duty 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. From our 2.4x2.4m gazebo to our 4x8m marquee, our hexagonal aluminium delivers strength and safety.

50/58mm Hexagonal Aluminium Marquee Frame

The heavy-gauge, 50mm (58mm diagonal) 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 Heavy Duty 3x4.5m gazebo is an investment for many years of dependable outdoor events.

Australian Standards Section 238 compliant product icon - Altegra Heavy Duty marquees and Pro Lite gazebos are structurally engineered for event marquee safety.

Prescribed Temporary Structures Certificate of Compliance (Section 238)

By designing and manufacturing our Heavy Duty 3x4.5m gazebos using Australian safety regulations and our valued customer feedback as the baseline, we can deliver an exceptional product that exceeds expectations. Australia holds particularly 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 commercial 3x4.5m gazebos in Australia. All our Heavy Duty marquees carry current structural computations from independent Australian engineers authenticating conformance with the Prescribed Temporary Structures requirements.

HRIA compatible icon - we've engineered Altegra heavy duty aluminium gazebos and marquees to the specific guidelines and requirements of the hire and rental association of Australia for safe public use, for reliability, and to last.

Engineered 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 that advocates 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.
