The GWM Cannon Alpha has quickly established itself as one of the most compelling utes in the Australian market. Strong safety ratings, a well-equipped cabin, competitive pricing, and a tub that is genuinely ready for work make it a serious option for both private buyers and fleets. As more Australians get behind the wheel of the Alpha, the question of how to protect and build out the tub properly becomes the first real decision to make.

The most practical tub upgrade you can fit to this ute is the GWM Cannon Alpha roller shutter. It weatherproofs your load, secures the tub from the outside, and integrates with the vehicle in a way that makes daily use seamless. But not all roller shutters are built equal, and a poorly fitted or generic cover on the Cannon Alpha’s tub profile will cost you more in frustration than it saves in price.

Here is what you need to know before you buy a GWM Cannon Alpha roller shutter.

Why Fitment Matters on the Cannon Alpha

The Tub Profile

The GWM Cannon Alpha has a specific tub profile, rail geometry, and sports bar configuration that varies from other popular utes on the market. A roller shutter that has not been purpose-built for the Cannon Alpha’s tub dimensions will sit poorly on the rail, create gaps in the weather seal, and in some cases will not integrate with the factory central locking or sports bar setup at all.

Generic or cross-platform roller shutters often require adapters or drilling modifications that compromise both the fitment and the resale value of the vehicle. The Alpha’s tub also needs to accommodate the PHEV variant’s charging port and other model-specific details depending on configuration, which a non-specific cover may not account for.

What to Look For

When evaluating a roller shutter for the Cannon Alpha, the key things to confirm are that the side rails are profile-cut specifically for the Cannon Alpha’s tub lip, that the cover is compatible with the factory sports bar configuration you are running, and that the central locking integration works directly with the GWM factory remote without additional hardware.

The HSP Roll R Cover for the GWM Cannon Alpha

Australian Manufactured, Cannon Alpha Specific

The HSP Roll R Cover is the only 100% Australian manufactured roller shutter available for the GWM Cannon Alpha. Built and engineered in Victoria, the side rails are individually profile-cut to match the Cannon Alpha’s specific tub geometry for a clean, factory-style fit with no adapters or modifications required. It is compatible with factory sports bars and suits both standard Cannon Alpha and PHEV variants. From $3,150.

Five Ways to Operate It

The Roll R Cover operates across five modes: the HSP app, an LED touchpad built into the side rail, the GWM factory remote, internal cab buttons, and Siri voice commands. The factory remote integration is one of the most practical features in daily use — double-tapping the existing GWM remote opens or closes the cover from the driver’s seat without any additional hardware.

The touchpad includes a digital security feature that only activates when the vehicle is unlocked, and can be programmed with a timed shutoff for added peace of mind. There are no physical handles on the outside of the cover, which removes one of the most common weak points on aftermarket roller shutters.

Security

The Roll R Cover uses cut-proof interlocking aluminium slats that cannot be compromised with a blade. The digital security system ties operation directly to the vehicle’s factory lock status, so the cover cannot be opened independently when the car is locked. For Cannon Alpha owners using their ute for trade work or parking in public areas regularly, this is a meaningful step up from covers that rely on a mechanical latch alone.

Water Protection

The Roll R Cover features the only external grate system on any roller shutter in the world, channelling water into a full-length gutter built into the side rails and exiting through four XL drainage points. The system is rated to handle over 60 litres per minute, which covers the kind of downpours Australian conditions regularly produce. The compact canister also retracts the cover 100% clear of the tub, maximising usable tub space when fully open.
