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

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

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

We have just purchased some cast iron radiators and they have a slightly uneven texture to the surface. What can we do about this.

Casting of iron is an imperfect processs. It is possible with some cast iron radiators that you will get minor imperfections in the surface finish. When radiators are painted this will reduce and over the years every additional coat of paint applied will provide a smoother more equal finish.

What is the difference between a pole winder opener and a telescopic opener?

What is the difference between a pole winder opener and a telescopic opener?

A pole winder opener has a fixed-length arm, making it suited to standard rooflight positions with a consistent throw. A telescopic opener has an adjustable shaft, allowing it to accommodate varying rooflight positions and throw requirements. For guidance on which suits your project, call 0333 987 4452.

Do your steel brackets have a protective coating?

Do your steel brackets have a protective coating?

Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.

We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.

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.
