ABACO – antibacterial and antiviral fittings

Antibacterial and antiviral fittings provide reliable and durable protection by acting not only antimicrobial but also antiviral.

The topic of health and hygiene is more important than ever in times of the coronavirus pandemic. We now know that the coronavirus is transmitted primarily by droplet infection and aerosols. But other pathogens, germs and bacteria are also frequently transmitted via the hands – and consequently often via door handles. Preventive hygiene standards, such as classic hand disinfection, are not always sufficient here to prevent contact infections. We all strive to minimize health risks and prevent infections.

After the actual pandemic situation, Almar Südmetall Group has worked hard to make ABACO® PVD coating more and more effective against viruses. It has been tested that the coating ABACO® is virucidal against the coronavirus strain MHV, the genus Betacoronavirus (same genus and family as SARS-CoV-1, SARS-CoV-2 / COVID19 and MERS). The above tests were performed by the Biology Institute of the University of Campinas – Brazil in accordance with the international standard ISO-BS ISO 21702: 2019 (first edition 2019-05-27). The Research and Development Department of Almar Südmetall Group has always strived to develop the ABACO® coating in order to constantly improve its properties.

ABACO® fittings therefore not only have an antibacterial and antimicrobial effect and begin to kill bacteria after only 5 minutes, but also have a bacteriostatic function, because already after the first contact with ABACO® bacteria are completely contained in their spread. From the 45th minute after contact the bacteria are killed and already after 2 hours ABACO® fittings promise 99.99% antiviral effectiveness.

What exactly is ABACO®?

ABACO® is a PVD surface which, in combination with silver ions, achieves excellent antimicrobial and antiviral efficacy. ABACO® was developed in our production facility Protec Surface Technologies. The PVD surface provides excellent resistance and durability by preventing the antimicrobial layer from scratching off, as is the case with a conventional coating. Furthermore, it ensures that ordinary daily use does not limit the effectiveness of ABACO®, but actually intensifies it.

Südmetall guarantees the antibacterial and antiviral properties of the surface for a period of 20 years.

In addition to its remarkable technical properties, ABACO® is also a true design wonder. Numerous models from the Südmetall range are available in ABACO® design and are available in stainless steel, chrome and gold surfaces. Fittings for outdoor use can also be selected in ABACO® surface without hesitation – the antimicrobial effectiveness remains unrestricted indoors as well as outdoors. ABACO® has been scientifically validated in accordance with JIS Z 2801:2010/A1 : 2012 – the highest standard – and ISO 22196 : 2007 (E). In accordance with DM and 3/21/1973, no precautions are required for the daily use of ABACO® products. The surface is completely safe for contact with humans.

What are the distinguishing features of ABACO® antibacterial fittings?

Record time

  • Bacteriostatic function: Already after the first contact with ABACO® bacteria are completely contained in their spreading
  • Antibacterial and antimicrobial effect: They begin to kill bacteria after only 5 minutes. From the 45th minute after contact all bacteria are killed
  • Antiviral efficacy: After 2 hours, ABACO® fittings promise 99.99% antiviral efficacy


ABACO® is characterized by extraordinary robustness and durability. Thus, the antibacterial and antiviral effectiveness is even intensified by increasing use over the course of the product life cycle. We guarantee this for over twenty years. You can find more information here.


Due to the use of PVD in manufacturing, there are numerous possibilities in terms of design. ABACO® fittings are available in stainless steel, chrome and Robusta Gold.


ABACO® can be applied to products of many different shapes. A major special feature is that its antimicrobial and antiviral effectiveness remains unrestricted even in outdoor applications. For this reason, our product range includes, among other things, protective fittings and push handles in ABACO® design, in addition to room door fittings.
