Built on experience. Driven by craftsmanship.

Mammoth Steel was founded with one simple goal: to deliver exceptional steelwork that combines engineering precision, outstanding design and quality craftsmanship.

With over 20 years of experience in the steel fabrication and installation industry, we understand the importance of getting every detail right. What began with a passion for bespoke steel staircases has grown into a specialist steelwork business offering three core services: Steel Staircases, Steel Doors and Structural Steel.

From striking architectural staircases and beautifully crafted steel-framed doors to essential structural beams and frameworks, we provide tailored solutions for residential and commercial projects.

Working with a trusted network of experienced designers, structural engineers, fabricators and installers, we bring together the expertise required for each individual project. From initial consultation and design through to manufacturing and installation where applicable, we aim to make the process straightforward, professional and efficient.

We believe exceptional steelwork is about more than strength and functionality. It’s about attention to detail, thoughtful design and delivering a finished product that complements its surroundings and stands the test of time.

Proudly based in Cheshire, we work with homeowners, architects, interior designers, builders and developers throughout the UK.

Whether you have detailed architectural drawings or simply an idea you’d like to explore, we’d love to hear from you. Get in touch to discuss your project — we’re always happy to help.
