The Asta is Shelta's top-of-the-range cantilever umbrella. What makes it so good is its strength and ease of use. Unlike other cantilever umbrellas, it can still be used when the wind picks up*. Add this to its ease of operation and premium materials like Sunbrella Acrylic and you’ve got a truly excellent umbrella. Guaranteed Sunbrella Acrylic canopy UPF50+

The Asta is a cantilever or side post umbrella meaning it has the post on the side as opposed to in the middle. This feature is great as it gives you maximum usability of the umbrella because you can cast the shade where and when you need it most. 

Shelta really has been clever in designing this brilliant new upmarket cantilever umbrella, outshining others that are similar. It is beautifully crafted from marine-grade materials including extruded aluminium castings, with stainless steel fasteners and cabling. The mast is a truly impressive 120 x 76mm section, and all frame components are engineered to achieve a 60km/h wind rating*! The frame is powder coated with a shadowy silver/anthracite combination, matched with high-quality Sunbrella acrylic fabric - the legendary 320gsm solution-dyed acrylic that is absolutely colourfast.

**The Price Match Guarantee must include the advertised price by a competitor that includes the shipping cost - Not pick up in-store. A written quote from the competitor must be provided with identical specifications. Excludes discontinued stock.**


  • Infinite tilt positions - almost variable to 55 degrees
  • 360-degree umbrella rotation
  • 8-position rotate lock via an insertable locking pin on the lower mast
  • Detachable crank lever for opening and closing
  • Retractable LED light bracket on umbrella hub
  • Protective polyester waterproof cover to keep umbrella protected when closed
  • Our favourite feature: The easy-to-use opening mechanism. Wind the lifting handle and the umbrella easily begins to open. Loosen the tilt knob and the arm rises almost automatically gliding into a tilt position. When the umbrella is fully opened, tighten the tilt knob at the desired angle and the umbrella is ready for use.

Shelta Asta Features Infographic

Although this umbrella has tested to 60km/h this is more a comparative indication of the strength of the umbrella and is not to suggest you can leave it open in 60km/h winds. The wind tunnel test has a consistent even wind coming from an optimal direction. Windy conditions are typically unpredictable and gusty. All cantilever umbrellas should be collapsed in breezy conditions. Wind damage is NOT covered by warranty.

*Please note: Colours may vary slightly between screens and the actual product. 



The structural aluminium frame is powder-coated with a shadowy silver/anthracite combination. 


This umbrella is available with a bolt-down base or inground base. When using the bolt-down option the area should be a large concrete surface of at least 10cm thick and steel reinforced. The base should be secured with 4 x M10 masonry anchors (sold separately).

For an inground installation, we can supply a specially made base which should be concreted into a hole of approximately 35cm diameter x 80cm depth (assuming firm natural ground). Typically 8 x 20kg bags of concrete are required (Rapidset concrete is not recommended).

Due to its heavy construction, the Asta is not suitable for a movable base option. 




The Asta baseplate has a diameter of 25cm. The 4 countersunk hole centres are 14.2cm and the diameter of the spigot (vertical tube) is 60mm (outside diameter).

This is the ideal umbrella for someone looking for a large cantilever umbrella that can be used during breezy conditions. Although it has been tested in a wind tunnel to 60km/h when opened, we strongly recommend using good judgment and closing the umbrella when the wind picks up. The umbrella is more susceptible to wind when in the tilt position and when tilted, the wind rating does not apply. See the warranty tab for more information. 

This is one of the strongest and most sophisticated cantilever umbrellas on the market and with proper care and maintenance, it should look great and provide many years of reliable and enjoyable service. It takes only a short time to learn the correct operation of this magnificent umbrella. You’ll find additional information about this product by using the Tabs at the top of the page.

Why is this umbrella more expensive than other Shelta cantilever umbrellas?

The Asta is a large, heavy-duty cantilever umbrella. The things which add to its cost include the very strong frame on which the umbrella is built and the premium quality Sunbrella acrylic canvas which is used to make the canopy.

Can I install this umbrella myself?

Sure, the umbrella comes fully assembled ready for installation. If you’re bolting the umbrella down to a concrete slab, you need to drill 4 holes and use masonry anchors (not supplied) to bolt it down. If you’re planning to install it into a grassed area, you need to dig a hole and concrete an in-ground base (optional extra) into the ground. Once this is done it takes a couple of strong people to lift the umbrella from its box and slide it over the spigot ready for use. 

Do I need any other bits and pieces to install it?

Yes. If you’re bolting down to a concrete slab, we recommend you purchase some anchor bolts from us when you purchase your umbrella. If your installing in-ground, you need to purchase the in-ground socket in addition to the umbrella itself. 

Can I leave this umbrella up all the time?

We recommend that you collapse the umbrella when not using it. Although it is a strong umbrella and is tolerant of windy conditions, it is always a good idea to fold it away when unattended or not in use.

What accessories do you recommend I purchase with this umbrella?

The anchor bolts for sure. Also, the umbrella does come with a protection cover but it’s relatively lightweight and only warranted for 12 months. If you really want to give your new umbrella the best possible protection we recommend you purchase an Extra Large O'Bravia cantilever protection cover. This will fit neatly on your new umbrella and give it the best possible protection. 

A LED light is also a handy accessory to purchase.  It simply clips onto a central drop-down arm. 

Can I get the Asta in other colours?

There is only one frame colour and four canopy colour options. If you are seeking a different frame and/or coloured canopy, look at the Sidepost Classic or the Queenslander cantilever umbrella, both of which are available in a wide range of colour combinations.


The Asta comes with a 2 year warranty on the frame and a 5 year fade resistant warranty on the fabric.

Warranty is on workmanship. It does not cover umbrellas which are damaged due to wind.

Please note, the standard polyester protection cover provided with the umbrella does not have a warranty. The upgraded O'Bravia cantilever protection cover has a 3 year fade resistant warranty and a 12 month warranty on workmanship.
