Light heavyweight commercial 3x4.5m Popup Marquee.

Reducing weight enhances portability. Our Geo42 frame takes a small step down in weight for a pared-down heavy duty aluminium gazebo that still packs a punch.

The Altegra aluminium gazebo frame has been the yardstick for leading quality, commercial-grade marquees since 2004. And when you asked for a more portable model to stand the test of time in all conditions, we listened.

The Geo42 frame combines redesigned geometric aluminium extrusions and slightly thinner sidewalls (.5mm thinner) to save 15% or 5.5kg from its Heavy Duty sister—the difference between struggling to set up and getting it done quickly and easily.

Starting at the critical ground-to-gazebo foundation are 140mm, bolt-free triangular galvanised steel footplates. An innovative internal wedge eliminates weak points for a more robust, more reliable ground hold.

8-sided geometric aluminium extrusions with 1.5mm sidewall thickness and 42mm diameter extend much-needed integrity from the ground to the canopy. Our incredibly strong cast-aluminium connecting joints secure frame parts and maintain a rigid hold, minimising movement in the windiest conditions.

We form the articulating upper gazebo scissor frame with diamond-shaped, 35mm aluminium truss pairs and an extended centre pole that contains a concealed tension spring. The result is a clean, robust and professional appearance.

Leading commercial safety compliance.

A hybrid by design, trimming down the load while leaning heavily on reliability.

The Geo42 3x4.5m marquee shares many of the traits of our commercially preferred heavy duty shelter - but with a lighter chassis.

We’ve developed the Geo42 3×4.5m marquee as the elegant middle point between our robust Heavy Duty 3×4.5m aluminium marquee and lightweight Pro Lite 3×4.5m aluminium gazebo.

The Geo42 sets itself apart by delivering reliability well beyond industry standards yet reducing weight by 5.5kg (compared to our Heavy Duty 3×4.5) to help ease the task of transport and setup.

While the Geo42 undeniably falls into the heavy duty gazebo category, the new geometric profile, slightly narrower aluminium sidewalls, and pared-down aluminium joints result in an impressive weight reduction.

A Lifetime Warranty and 100% rebuildable design means your Altegra Geo42 3×4.5m marquee is your heavy duty popup tent designed to enjoy for life.

Altegra Geo42 aluminium marquee corner joint - engineered geometric aluminium extrusions establish a robust foundation and extremely resilient cast-aluminium joints secure diamond upper frame parts.

Unassailable ALU Joints

The Altegra Geo42 frame joints are constructed with unrelenting cast aluminium for maximal integrity and the easy to use, ring-pull height adjustment system is built to last.

Our dedication to innovation and continual improvement often results in simplified components. Our gazebos are complete with parts that last longer and work with less effort.

Select 330GSM Polyester Fabric

Quality 330GSM PVC-lined Polyester is the choice fabric for our Elite canopy. The balance of foremost protection, pliability, durability, and professional appeal.

The Altegra Elite canopy has been gusseted and reinforced throughout as a measure to protect from wear caused by friction between the frame and the material.

Thorough Friction Reinforcing

Reinforced for longer life and a stronger hold, all frame-to-material wear points are fortified with additional fabric and are held firmly with Velcro. The result is reduced wear and enhanced durability.

High Ground in a downpour

Avoid water pooling, a common marquee canopy trait with extended canopy peaks and top quality material. High peaks and durable material retain tension and optimal water runoff.

Endure turbulent times As one

A strong marquee needs to be united to remain intact in adverse conditions. The Altegra Elite canopy is extensively secured to your portable shelter by easy to use Velcro anchors.
