The development of Steriall® alloys was made possible by the Lebronze alloys group's in-depth knowledge of technical copper alloys. After several years of Research and Development carried out with the help of the Fonderephar microbiology laboratories in Toulouse and the University of Reims Champagne Ardenne, the Steriall® solution has been oriented towards alloys with more than 75% copper, the only ones capable of ensuring an interesting efficiency.

Steriall® E alloy

For unequalled protection over time, our R&D teams have developed the Steriall® E alloy.

Independent bacteriological laboratory tests demonstrate a major activity of the Steriall® E alloy.


It has a champagne colour and a durable surface finish over time.


It should be noted that any application of varnish or paint totally inhibits the properties of Steriall® alloys and is totally prohibited.

The Steriall® study in EPHAD/MARPA

Available via this link, this study has just been carried out in partnership with the University of Reims Champagne-Ardenne (URCA, EA 4691) and four EPHAD (Residential Establishment for Dependent Elderly People) and one MARPA (Maison d'accueil et de résidence pour l'autonomie) in Champagne-Ardenne. These 5 establishments represent a capacity of 800 Residents.

1000 door handles and 1000 metres of Steriall® ramps were installed. This is one of the largest studies in the world using copper products, led by a scientific committee of academics and health professionals.

The aim of the study is to measure the impact of Steriall® products on the bacterial flora present in buildings.

Dr Vincent Stoeckel, co-pilot of the Scientific Committee believes that:

« According to the World Health Organization (WHO), we are moving into a post-antibiotic era, and common infections could become increasingly dangerous for at-risk populations such as the sick and elderly. If this experiment proves positive, it could lead to a significant breakthrough in the fight against bacteria in healthcare facilities.»

The Cuprocare Study

Started in 2016, this study is carried out in partnership with the University of Reims Champagne Ardennes (URCA, EA 4691, EA 4695). Its aim is to improve understanding of the operating principle of Steriall® products in order to further improve their efficiency and aesthetics. The choice of alloys, their finish and the cleaning procedures of the Steriall® range are the result of this research.

Cuprocare is co-funded by the European Union. Europe commits itself in the Grand Est region with the European Regional Development Fund.
