What and where we are?

Welcome to BM Steels, the steel-framed building company based on the Surrey / Kent border. We are professional and friendly, providing steel buildings within the industrial / commercial / agricultural steel construction sector. We produce buildings of all shapes and sizes to suit your exact project needs. Our projects are mainly within the south-east, but we are happy to cover projects across the UK.


David Mindham & Simon Barren have been friends for over 50 years and have assisted each other on various construction projects over that time. They decided to merge their skill sets and their businesses and Carnegie Steel Buildings T/A BM Steels was born. David has 40 years’ experience in the metal work and the steel industry and Simon has 35 years in running events and construction projects, as a result, they have created a company with extensive knowledge of the steel construction industry.

Why we do it

It’s simple, it brings us enormous satisfaction to help our clients realise their vision and build them a solid commercial steel structure from concept to completion. During that process, we want to minimise any stress and allow our clients to get on with their lives and business.
