What size cast iron hopper head do I need for my project?

What size cast iron hopper head do I need for my project?

The right size depends on the width of your gutter run and the volume of water you need to collect. The Strayton H42A is available in four widths: 305mm (12"), 355mm (14"), 457mm (18"), and 610mm (24"). As a general guide, wider hoppers suit larger roof areas and heavier rainfall zones. If you are unsure, our team can advise based on your gutter profile and catchment area — call 0333 987 4452.

What pipe connection sizes do your cast iron hopper heads accept?

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.

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

What building types is the Iron Works Patterned Hit & Miss Vent suited to?

The Iron Works Patterned Hit & Miss Vent suits Victorian and Edwardian buildings where decorative cast iron or brass ventilation grilles were part of the original specification — including terrace houses, civic buildings, churches, entrance halls, and estate properties. It is appropriate on listed buildings and conservation area properties as a like-for-like decorative vent replacement, and on new heritage-quality construction where period detailing is required.

What paint finish should I use on cast iron guttering?

What paint finish should I use on cast iron guttering?

Linseed oil paint is the most appropriate finish for cast iron guttering on listed and historic buildings. It is breathable, flexible, and penetrating — qualities that suit the movement characteristics of cast iron through seasonal temperature changes. Tuscan Foundry Products offers a curated range of heritage linseed oil colours. For modern applications, a high-quality exterior oil-based paint system over a metal primer is also acceptable.
