The Trantthorpe No.86 is unlike anything else we cast. Its upper body carries deep bands of raised studs — rows of heavy round bosses encircling the head — above a smooth conical taper that funnels to the outlet.
The studding reads as riveting, and that is precisely the association it carries: the language of structural ironwork, boilerplate and engineering rather than of domestic architecture. Cast deep and repeated in courses around the full circumference, it holds shadow from every angle and gives the casting a solidity that photographs particularly well.
That makes it a specialist choice, and a very good one on the right building. Industrial heritage conversions, mills and maltings, engine and pump houses, dock and railway architecture, breweries — buildings whose original ironwork was riveted and unapologetic. It also works on robust Romanesque and Norman Revival work, where the studding sits comfortably alongside chevron and billet ornament.
On a refined domestic elevation it would be entirely wrong, and a plain pattern is the correct specification.
Cast in solid iron to BS 460:2002, supplied in primer or black as standard, with heritage colours and traditional linseed oil finishes available on request.

Yes. Cast iron hopper heads are the historically correct choice for listed and period buildings, and a like-for-like cast iron replacement is generally accepted without objection by conservation officers. We manufacture to BS 460 for genuine heritage character and durability.
The physical properties of cast iron are sustained throughout its working life, so with proper maintenance we'd expect our gutters and pipes to last over 100 years under normal conditions.
Our cast iron hopper heads are available with 65mm, 75mm and 100mm round outlets, 75mm, 100mm and 125mm square outlets, and 100x75mm, 125x100mm and 150x125mm rectangular outlets, to match the downpipe already on site or specified for the project.
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.
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.
