Trelawny is a leading supplier of surface preparation equipment with major operating divisions in the UK and the USA, a joint venture in Germany and a worldwide network of distributors. Its products are used to clean by mechanical means a wide range of substrates in an efficient and environmentally acceptable fashion. It pioneered the use of Tool & Vacuum System (TVS) as an alternative to blast cleaning to permit point-of-generation containment of hazardous materials, dust and debris. A complimentary portable Contained Blasting System (CBS) allows the simultaneous recovery of contaminants and spent blast medium.

Navies, shipping fleets and oil platforms around the world are equipped with the Trelawny range of pneumatic and electric surface preparation tools from hand-held needle scalers to manually guided large area deck de-scalers. The patented Vibro-Lo (low vibration) range of pneumatic tools has lead the way in protecting operators against exposure to excessive vibration levels.
