Diamond Spiral Stairs

Blending Style & Practicality

Unique to British Spirals & Castings, Diamond pattern spiral stairs provide a decorative twist on the uniform patterns common in the Georgian period.

The versatility of the design means you can marry the tread up with a host of different baluster optiond, whether it be our more decorative infill panels or simple square or circular profile spindles.

As with our other ranges, these aluminium staircases are cast at our foundry in Staffordshire. At a third of the weight of cast iron, these staircases are suitable for both internal and external spaces, including second floor access and loft conversions.

Landing Plates

Every spiral staircase requires a landing plate, they tend to be either 60 (triangular shaped) or 90 degree (square shaped) rotations and can either be made with a cast top to match the treads, or taken to your finished flooring. We can manufacture landing plates to either a radius or square edge to fit circular or square openings. You can build your own as part of the floor.

Do you offer a fitting service?

We are only able to offer a fitting service for clients in the London area. However, all our products are designed for local tradesman and DIY enthusiasts to be able to install, and because they will have been fully erected in our workshop and made to measure there is very little work to be done on site if correct dimensions have been supplied. Full fitting instructions are sent out with the staircases.

What staircase diameters do you offer?

We can manufacture staircases in a range of diameters from 970 mm to 2600 mm depending on your project requirements. The minimum diameter may depend on local Building Regulations and what the space being accessed via the staircase is used for.

Can I order a custom design of casting?

Yes, we can create entirely one-off custom castings at our foundry or work with steelwork partners to produce laser-cut steel panels.

Get in touch to discuss your ideas.

Why do you use cast aluminium for your spiral stairs?

Cast aluminium is virtually indistinguishable from cast iron but provides a number of benefits. It is typically much lighter (in some cases weighing around a third of a cast iron design). This makes them much easier to install and can also reduce the structural loading in existing buildings or the size of footing needed in gardens. It is also less brittle and offers excellent corrosion resistance.

Do you have a showroom that I can visit?

Yes, we do. There is a full showroom at our workshop in Chapel-en-le-Frith. The Derbyshire showroom is open from 8 am – 4 pm Monday to Friday. We strongly encourage prospective clients to visit the showroom if they can so that they can see all the different options available and get a feel for the different diameters and quality of the product.
