Welcome to Blue Diamond STL™

Welcome!  We are Blue Diamond STL a family-owned business and global supplier of a comprehensive range of fast-moving, high quality goods to the construction and industrial sectors. Based in Doncaster, South Yorkshire, UK, since 1982, we offer global reach with a personal service.

I have now been trading with Blue Diamond for over three years and during all that time I have found you and your company to be very professional in all its dealings.

The price file was set up and maintained giving no account queries.

I have not had reason to raise a debit note for any shortages or incorrect deliveries, these factors help the smooth running of an account and causes no extra costs to either business.

Whenever I have had contact with Blue Diamond I have been treated in a friendly and courteous manner both on the phone and face to face.

All customer technical questions on the product have been dealt with efficiently either by phone or personal visit anywhere in the country.

I have no hesitation in recommending Blue Diamond as a professional company with a top quality product range and staff knowledge and willingness to back it up.
