6x4" Moulded Ogee Cast Iron Guttering

The 6x4" moulded ogee cast iron gutter is often the point where people stop scrolling and think, yes — that’s the one. It’s generous without looking oversized, decorative without being fussy, and practical enough to deal with real-world rainfall. Especially the kind we get now.

If standard ogee feels a touch small, or you’re working with a larger roof area, this size usually makes sense straight away.

Why choose the 6x4 cast iron size?

The 6x4" moulded ogee profile offers increased water capacity compared to smaller cast iron guttering options, making it a solid choice for Victorian townhouses, period commercial buildings, or any property with a wider roof span.

It’s still traditional in appearance - still very much at home on heritage buildings - but it handles higher volumes of rain with less risk of overflow.

It’s commonly specified where visual balance matters. A deeper gutter can actually look more proportionate on taller façades, especially when paired with cast iron downpipes and hopper heads.

Traditional moulded ogee profile (done properly)

Like the rest of the range, this 6x4 moulded ogee cast iron guttering is traditionally sand cast, giving it a crisp front moulding and that slightly textured finish modern systems like steel guttering struggle to replicate. It’s manufactured to BS460:1964 and complies fully with heritage and conservation requirements — which tends to matter when approvals are involved.

If you’re comparing profiles, it’s worth also looking at Victorian ogee cast iron guttering or standard moulded ogee cast iron guttering elsewhere in the range. The differences are subtle on paper, but noticeable once installed.

Finishes: primed or painted black

The 6x4 moulded ogee guttering is available in:

• Primed cast iron – ideal if you’re matching existing paintwork or planning a bespoke finish

• Painted black cast iron – supplied ready to install and suits most period properties immediately

Both finishes offer the same strength, lifespan, and traditional appearance. The choice really comes down to how much control you want over the final look.

Installation notes (worth reading once)

A few key points installers tend to appreciate:

• Fascia Brackets are required for all running outlets and angles, no more than 300mm from a joint

• Rafter top-fix, side-fix, or rise and fall brackets should be fitted at maximum 915mm centres

• Allow 3–4mm expansion gaps within sockets

• Joints should be sealed using a Britannia cast iron jointing kit or Dow Corning 791 sealant, secured with M6 x 25mm bolts, neoprene washers, and nuts

All components come with free fixings and a joining pack, and full fitting instructions are supplied with every delivery.

The 6x4 moulded ogee cast iron gutter does sit at the higher end of cast iron guttering cost — mainly due to size and material weight. But once installed, it’s remarkably stable, low-maintenance, and capable of lasting decades with basic care.

For larger period properties, it’s often the size that feels right both visually and practically. No compromises. Just something that works — and keeps working.
