Built on experience. Driven by craftsmanship. Staircases with backbone.

Mammoth Steel was founded with one simple goal: to design and build exceptional steel staircases that combine engineering precision with outstanding design.

After 20 years working within the steel fabrication and installation industry, we recognised an opportunity to create a company dedicated entirely to bespoke staircases. We take you from design to completion, bringing your vision to life.

Whether it’s a striking centrepiece in a contemporary home, a robust staircase for a commercial development or a multi-storey staircase, our focus remains the same: exceptional quality, delivered on time with meticulous attention to detail.

Working with a trusted network of experienced designers, fabricators and installers, we manage every stage of the project—from the initial consultation and design through to manufacture and installation—ensuring a seamless experience and an outstanding finished product.

We’re proud to be based in Cheshire and to work with homeowners, architects, interior designers, builders and developers across the UK.

Get in touch with your project today, our friendly team are on hand to answer any questions. Wether you have the finished design or just the concept, we’re always happy to help!
