A genuine cast iron rainwater pattern the G46 or No.46 is available in two profile sizes. The profile is a larger version of the more traditional ogee (OG) curved pattern and offers increased capacity.
The cast iron G46 moulded gutter nozzle outlet connects the G46 gutter run to the downpipe, forming the transition between horizontal drainage and the vertical pipe drop. The full G46 moulded profile is maintained at the outlet, preserving the visual consistency of the installation on the large Victorian and Edwardian buildings where this pattern is commonly found.
Manufactured in solid cast iron to BS 460:2002. Available in both G46 profile sizes: 125mm (5″) and 150mm (6″). Supplied in primed or factory black finish. Connects to a standard round cast iron downpipe at the base. The G46 nozzle outlet is not interchangeable with common ogee fittings.
Specified on listed buildings and heritage restoration projects where the G46 moulded pattern is the historically correct profile. Accepted by conservation officers as the appropriate fitting for period rainwater work on substantial Victorian, Edwardian, and later period buildings.
Compatibility: G46 moulded cast iron gutter 125mm and 150mm only. For specification support, call 0333 987 4452.

It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.
Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations. It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience
As well as being easier to produce, the material enabled eaves gutters to be installed more simply, since lead could only be used in this location as a lining for timber gutters. Many modern materials focus on replicating the appearance of cast iron but those materials can vary rarely offer any of the benefits. Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance.
Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make cast iron an ideal choice for both traditional and modern installations. It is not uncommon to see modern alternative products marketed with terms like low maintenance or easy to install and cost effective. It has even been said that ‘plastic guttering systems provide a way of achieving a traditional look with modern convenience’.
These terms tend to refer to possible cost savings rather than any real product benefits. It is also difficult to quantify the benefits of modern convenience over traditional build quality. It is worth remembering that all rainwater goods will require some element of maintaining to ensure they are unblocked by debris and remain functional. No rainwater system cleans itself.
Today most suppliers of cast iron rainwater systems offer products in both primer or pre-painted with a 10 year protective coating. When describing modern materials, the term ‘cost effective’ is used rather than simply saying cheap. There is no doubt that the initial cost of many modern materials is less than cast iron but you might be surprised to know that over its lifespan, cast iron will cost around a third of plastic.
Bespoke and copy cast iron rainwater goods typically have a lead time of 8 to 10 weeks from order confirmation. This covers pattern-making, casting, finishing, and quality inspection. Standard stock items are available for prompt dispatch. We always recommend confirming lead times at enquiry stage so your project programme is not affected.
The Calnethorpe is designed for formal classical and Georgian elevations where scale and material authenticity matter — large townhouses, country houses, manor houses, and institutional buildings. It is also widely specified for new-build heritage projects where cast iron rainwater goods are required to conservation standard.
Tuscan Foundry's cast iron hopper heads are available in Standard Black and Heritage Colour finishes. A linseed oil paint finish is also offered — a sustainable, vapour-permeable option particularly appropriate for listed buildings and conservation projects. Heritage colour swatches are available from the team on request.
BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.
Yes. Cast iron is the material required by most conservation officers and listed building consents for the replacement or replication of traditional rainwater goods. Our hopper heads are produced in solid cast iron and we can assist with specification notes or material statements for planning purposes if required.
Hopper heads are supplied in red oxide primer ready for on-site painting, or pre-finished in black. A full range of Heritage Colours in traditional linseed oil paint is also available on request — please contact us for the swatch chart.
The H1 is available to accept round pipe connections in 65mm, 75mm, 100mm, and 150mm diameters. The 65mm and 75mm variants measure 305mm wide by 197mm deep and 210mm high. The 100mm variant measures 355mm wide by 230mm deep and 240mm high. A 150mm connection option is also available — please contact the team for dimensions.
