UK delivery from £30. Fittings are despatched boxed. See delivery rates.

The Rectangular Pipe Offset Front steps a cast iron rectangular downpipe in or out from the wall, through the broad face of the pipe, where the wall face changes plane. It keeps the pipe vertical above and below the step.

Offsets are made as a single casting with two 112.5° bends and a straight between them, giving projections from 56mm to 610mm. The head carries the moulded socket band, available eared with integral fixing ears, or un-eared for runs fixed with holderbats or earbands.

Front offsets take rectangular downpipes around plinths, string courses, cornices and window sills. Where the pipe needs to step sideways along the wall rather than outwards, use the Rectangular Pipe Offset Side.

All fittings in our rectangular range are cast iron to BS 460:2002, made to the same moulded profile so pipes and fittings line up neatly on the elevation. Every fitting is supplied either in primer, ready for painting on site, or in factory black. For listed buildings and conservation areas we also offer hand-applied linseed oil paint in heritage colours, which stays breathable and flexible and is straightforward to maintain. Stocked items are usually dispatched within 5 to 7 working days; allow around 6 to 7 weeks where a linseed oil finish is specified.

Rectangular pipe sizes: 100mm x 75mm (4″ x 3″), 125mm x 70mm, 125mm x 100mm (5″ x 4″) and 150mm x 100mm (6″ x 4″).

Suitable for listed buildings, conservation areas and heritage restoration. For specification support or a project quotation, call 0333 987 4452.

Do other materials offer the same benefits as cast iron?

Do other materials offer the same benefits as cast iron?

The drainage and guttering market has matured considerably over the past 20 years and there are now many more product choices for consumers to consider.

Despite the influx of new materials it appears that the benchmark for rainwater systems is still cast iron. Cast iron rainwater goods were introduced in the late 18th Century as an alternative to lead. 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.

It is easy to forget about your rainwater system but it does need to be maintained and inspected at least twice a year regardless of the product material. It does not matter whether the property is hundreds of years old or brand new, the message is the same; ‘maintaining your rainwater system contributes to the external appearance of the building as well as keeping it free from damp and structural damage.

What building types is the H528 cast iron hopper head suited to?

What building types is the H528 cast iron hopper head suited to?

The H528 measures 760mm wide x 370mm deep x 565mm high, making it well suited to the largest properties in the range — substantial country houses, civic buildings and ecclesiastical projects.

What if my building’s existing gutter profile isn’t in your standard range?

What if my building’s existing gutter profile isn’t in your standard range?

Where a standard profile can't match an existing design, we offer a bespoke casting service in association with our pattern makers, typically with a 12–14 week lead time. Please call 0333 987 4452 or use the contact form to discuss your project.

Is a cast iron hopper head suitable for use on a listed building?

Is a cast iron hopper head suitable for use on a listed building?

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.

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 finishes are available on your cast iron hopper heads?

What finishes are available on your cast iron hopper heads?

Cast iron hopper heads from Tuscan Foundry are available in Standard Black (a factory-applied primer and topcoat finish) and Heritage Colours. A linseed oil paint finish is also available, providing a vapour-permeable, historically authentic coating that is particularly appropriate for listed buildings and conservation projects. Full finish specifications are available from the team.
