Our 115mm Beaded Half Round cast iron guttering takes the familiar half-round profile and adds a raised bead along the outer edge of the gutter.
It is a fairly small detail, but once installed it gives the rainwater system a noticeably more traditional, decorative finish.
Also known as 4.5-inch Beaded Half Round guttering, this profile works particularly well on Victorian and Edwardian properties, period renovations, cottages and heritage-style projects where a completely plain gutter can sometimes look a little too simple. The 115mm size also keeps the proportions sensible for a typical domestic roof rather than introducing an unnecessarily large gutter profile.
The Alumasc Beaded cast iron Apex Heritage system includes matching gutter lengths, unions, stop ends, angles, outlets and brackets, allowing the decorative profile to continue consistently around the building. Complete the rainwater system with our cast iron downpipes, or add one of our cast iron hoppers where valleys or other roof outlets need to discharge into the downpipe.
The Alumasc Beaded Half Round system is available in traditional black, primed and selected custom colour finishes, giving you plenty of scope to match existing rainwater goods or the wider exterior of the property.

Popular black painted and primed cast iron products are usually available for next working day delivery when ordered before 11:30am, subject to stock. Custom RAL colours normally take around 7–10 working days.
For many UK homes, 115mm or 125mm guttering is a common choice. Smaller roof areas such as porches and outbuildings may use 100mm, while larger roofs or longer runs may need 150mm. Roof area, gutter profile and the number of outlets all matter, so it is worth checking before ordering.
Yes. We supply matching cast iron downpipes, hopper heads, brackets, outlets and fittings across the range, so you can put together a complete rainwater system rather than mixing different manufacturers or profiles.
Yes. Alongside painted black and primed finishes, many cast iron gutters, downpipes and hoppers can be supplied in custom RAL colours. Bespoke finishes are usually supplied within 7–10 working days.
Standard products can usually be returned within 30 days of delivery, although returns after the first 14 days may be subject to a restocking or handling charge. Made-to-order and custom-colour items are non-refundable, so it is worth checking sizes and finishes carefully before ordering.
Painted black products arrive with the finished colour already applied and are ready to install. Primed products are intended for projects where you want to apply the final decorative finish on site.
Normally, no. Plain Half Round, Beaded Half Round, Victorian Ogee, Moulded Ogee and Deepflow all use different shapes and fittings. It is best to keep the gutter lengths, unions, angles and outlets within the same profile and size.
Send us a photo and a few measurements. The overall width, depth, profile shape and downpipe diameter are usually enough to narrow it down and help identify the closest matching system.
You can buy individual components. We stock gutter lengths, unions, angles, stop ends, outlets, brackets, downpipes, bends, shoes, hopper heads and sundries separately, which is useful for repairs as well as complete installations.
Yes. If you have plans, elevations or even a marked-up sketch, send them over and we can help work through the likely gutter lengths, outlets, downpipes, angles and fittings required.
