Steriall / Groupe Lebronze alloys

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.

Steriall®’s antimicrobial power is 10 times more powerful than the most demanding standard about antibacterial power !

On each of the germs retained by the NFS 90-700 norm attesting to the antimicrobial power of a material, Steriall® copper alloy has demonstrated an effectiveness 10 times higher than the requirements of the standard.

In the laboratory, Steriall® eliminates 99.9% of the microbes deposited on its surface in 1 hour for each of the 4 germs Escherishia Coli, Staphilococcus Aureus (resistant to antibiotics), Pseudomonas Aeruginosas, Enterococcus Hirae, whereas obtaining this standard requires a reduction of at least 99%.

However this norm is applied to new materials under laboratory conditions, while real conditions can weaken the antimicrobial power of Copper. The Steriall® research goes beyond: it aims at proving and optimizing the benefits of Copper in building, under real and usual conditions.

Steriall® is effective against human coronavirus. The antimicrobial power of Copper is active against bacteria and also all the types of viruses Lebronze alloys had tested. Coronaviruses are no exception: even though they persist a relatively longer time than other microbs on a surface. Our laboratory test on HCOV-299E on a Steriall® contact surface proved that its concentration drops in a few minutes. Steriall® eliminates 61% of the viral load in 15min, 98% in 1 hour, and 99.9% after 4 hours, it works days and nights!!

These results from FONDEREPHAR labs in Toulouse, France, are consistent with international studies on SARS-COV-2, responsible for Covid19: this virus can persist for several days on steel and plastic surfaces, but it is quickly eliminated by Copper.

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.
