Alumasc Cast Aluminium Beaded Half Round Guttering

Beaded cast aluminium guttering is one of those profiles people don’t always clock straight away - until it’s pointed out. Then it’s hard to unsee. That subtle bead along the front edge gives just enough definition to lift the roofline without drifting into full Victorian ornamentation.

It’s often chosen where standard aluminium profiles feel too plain, but full Victorian ogee aluminium guttering might be a step too far. In that sense, it sits comfortably alongside aluminium moulded ogee guttering and other traditional-style options within the wider aluminium guttering range.

Why choose a beaded profile?

The beaded detail adds visual weight without overwhelming the building. It works well on period homes, traditional refurbishments, and sympathetically designed new builds where clean lines still matter.

Because it’s cast aluminium, the system is:

Lightweight and easy to handle on site
Resistant to rust and corrosion — even in harsh UK weather
Capable of lasting up to 40 years in rural or suburban environments
100% recyclable, which makes it a sensible long-term material choice

It delivers the look people associate with heritage guttering, without the installation challenges of cast iron rainwater.

Finish options & lead times

Beaded cast aluminium guttering is available in a wide range of finishes, with clear delivery timeframes:

Textured black – ships next working day!
5 textured heritage colours – ship in 5-7 days
26 standard matt RAL colours – ship in 2 weeks
Plain mill finish – supplied ready for on-site painting

If you need something more specific, bespoke RAL or BS colours can be supplied to order to match existing windows, downpipes, or architectural features.

Part of a complete aluminium system

This profile is designed to integrate with matching aluminium downpipes, cast aluminium hoppers, and compatible brackets and fixings. Keeping everything within the same system helps maintain consistent proportions and finishes — especially important when mixing visible components across elevations.

If you’re comparing profiles, it’s often viewed alongside cast aluminium Victorian ogee guttering, aluminium moulded ogee guttering, or simpler modern aluminium gutters, depending on how decorative you want the final look to be.

Installation Notes for Beaded Aluminium Guttering

For best results, joints should be made using:

Low modulus silicone sealant (such as DOW 791)
M6 x 20mm aluminium bolts and washers to achieve a tight, secure joint

The system is straightforward to assemble, forgiving on site, and well suited to both new installations and replacement projects where access or handling space is limited.
