AATi Ltd (formally Antislip Antiwear Treads International Limited) formed in 1984 and adopted the traditional London Underground cast stair tread designs which have been an enduring and very effective feature on the UK rail network for over 50 years.
The company has developed its product range to encompass DDA (Disability Discrimination Act) requirements in modern stairway design, also focusing on uses outside the traditional markets; light rail, over-ground, station terminals and a wide range of commercial and architectural applications. All products are designed and manufactured in the UK.
AATi has now become part of the FSE Group, specialists in a wide range of cast metal products. This is a privately owned organisation, and nominated supplier to Transport for London companies and Network Rail.
