Open Ends vs Closed Ends. Why does it matter?

These two images show the exact same batten facade by Caloundra Lace in Caloundra, QLD. The only difference? One is finished with Nelsons CNC Aluminium End Caps. The other isn’t.

It’s a small component, but it has a big impact. On elevated facades like this, the underside of every batten is visible. Finishing each one with a precision-machined aluminium end cap transforms exposed hollow sections into a clean, architectural finish.

Caloundra Lace is known for delivering exceptional aluminium fabrication, and this project is a great example of the attention to detail that goes into every installation. We’re proud our aluminium end caps were chosen to complete the job.

This aluminium batten screen is fabricated from 50x50 SHS with a 1.6 mm wall thickness and 6 mm external radius corners, finished with our 50x50x1.6 R6 Aluminium End Caps (SKU: 505016R6). Precision-machined for a secure interference fit, they install without welding, screws or glue to deliver a clean, professional finish.

Our Nelsons CNC 50x50x1.6 R6 Aluminium End Caps are:

- Precision-machined from 6060 T5 aluminium to perfectly fit specific external dimensions and wall thickness and made to match external corners.
- Designed with a secure interference fit
- Made in Australia
- Available in 700+ sizes

Because great fabrication deserves a professional finish.

Timber-look finish. Precision-fit end caps. 👌

A premium aluminium batten fence deserves an end cap that fits just as well as it looks.

Our aluminium end caps are supplied in mill finish (raw aluminium), allowing them to be sent alongside your aluminium battens to be powder coated, anodised or finished with a timber-look sublimation coating.

Looking for a timber-look specialist? Nelsons CNC End Caps works closely with Kote It Au
who can apply a matching timber-look finish to both your aluminium battens and end caps. Once finished, the end caps are simply installed, creating a seamless colour and timber grain match across your entire project.

Unlike loose-fitting alternatives, our precision-machined aluminium end caps are designed for a tight, secure fit, giving your aluminium batten fencing a premium finish from every angle.

🎥 Tomorrow we’ll show you just how easy they are to install.
