What started back in 1889 in Cologne, Germany, with a lot of courage and pioneering spirit, has today evolved into a specialised company whose expertise is much in demand all around the world. Now, as it did back then, STEINERT benefits from the advantages of a family-owned business: stability, respectability, continuity, and flexibility. Since 1931, STEINERT has been not only been backed by the Buchholz family, but by an entire company group.

The individual companies operate in different markets: STEINERT and RTT STEINERT develop innovative separation technologies, while Anofol - a division of STEINERT - have gained an excellent reputation in the area of metal surface finishing and electronic industry.

All in all, a long-term diversification strategy that allows us to bundle our development know-how and utilise your benefit.


Due to its vast experience with separation technology, our ANOFOL business unit can offer high-precision coils of anodized aluminium strip for electrotechnical applications. Our customers worldwide greatly benefit from the wide range of applications associated with these coils.

External management, a highly motivated team, and the strengths of an independent family company — all these things together make it possible for us to plan for the long term and act in a sustainable manner. In this way, we can always take account of new points of view and continue to develop innovative new ideas. This background, the regular dialogue with our customers, and our high willingness to invest generate state-of-the-art technology and efficient production methods.

In conjunction with an open communication structure and a cooperative leadership style, mutual appreciation and respect result in a highly motivated workforce. We invest in our employees’ training and professional qualifications. Active development of personnel promotes employee motivation and opens up the possibility of further development within the group of companies.

We strive to operate in a sustainable manner — and will continue to do so in the future.

With our applications, we will make further intelligent solutions available and thereby play a role in reducing the environmental impact of various activities.

We regard ourselves as leaders when it comes to innovation and will continue to drive progress forward in all of our business fields. Our in-house development department and our close relationships with universities and research facilities will ensure that we live up to our expectations.

We use our knowledge to provide our customers with optimal solutions for the widest possible range of application fields.

Tradition is both a commitment and the basis for long-term success. It is the company's history that lends STEINERT its indispensible identity. Documents dating back more than 100 years testify to the early pioneering achievements of Ferdinand Steinert, the company's founder. Steeped in history, they are the origin of a development spanning from separating compact iron chunks to high-tech filtering of tiny microparticles.

2009 to the present

RTT Systemtechnik GmbH at Zittau and STEINERT decided to develop and produce together the sensor sorting systems of UniSort under the new traded company RTT STEINERT GmbH.

Relocation of STEINERT US Headquarters to Greater Cincinnati area.


By the end of 2007, around 2200 non-ferrous metal separators, featuring an eccentric magnet system, had been sold, making it the best-selling eddy current separator worldwide.

The acquisition of a majority share in RTT Systemtechnik GmbH Zittau and changing the company's name to RTT STEINERT GmbH in 2009 completed the product range. 

2004 – From Australia to China

Acquiring the operations of the Sturton-Gill company in Australia in 2004 marked an important step towards establishing a worldwide customer orientation. Under its new name, Melbourne-based STEINERT Australia Pty. Ltd. ranks among the leading magnet manufacturers in the Asian-Pacific region, supplying both the growing recycling industry and the thriving minerals industry there. A significant portion of the products is exported from Australia to China.

2003 – STEINERT goes USA

In 2003, the company launches its HGS high gradient magnetic separator for separating ultra-fine paramagnetic particles in salt and construction chemicals.

The overwhelming success of STEINERT's products on the North American market leads to the founding of STEINERT US LTD in St. Petersburg, Florida, a joint venture with the company's longstanding representative in the USA. Customers across the USA quickly benefit from the established infrastructure, and reward the move with a substantially increased order volume.

STEINERT 2000 plus – New products and global alignment

The new millennium starts with the systematic introduction of a new generation in the company, as well as intensive research and development activities that will enable the launch of new, and in some cases unique, equipment on the sorting technology market. 

Advancements in the sensor and computer technology segments facilitate the targeted development of the FSS® colour sorting system and the ISS® induction sorting system. Both device types aim at further increasing the metal output by utilising fully mechanised processes. In particular, the ISS® induction sorting system, first introduced in 2001, gains worldwide acceptance on the metal recycling market during the time of the raw materials boom. 

With the development and launch of the HGF high-gradient magnetic filter, STEINERT breaks new ground in the industry. For the first time, the permanent magnet matrix separator makes it possible to separate ultra-fine magnetic components from process fluids with an efficiency of more than 90 %. Today, the HGF is used all around the world. 

1889 – Foundation of the STEINERT company

Right from the start, the mission of the company's founder Ferdinand Steinert is clear: efficient recycling!

In 1889, Ferdinand Steinert established 'Ferdinand STEINERT Elektromagnetische Aufbereitungsanlagen' company in the metropolitan city of Cologne, Germany. The new enterprise starts out small, but the market for separator magnets is huge, because the phenomenon of magnetism, although known since the eleventh century, has thus far only been commercially exploited to a very limited extent.

The steel industry is one of the company's first customers. F. Steinert, a designing engineer by trade, develops magnets that can be used to recover iron from steel slag and debris as well as from foundry and steel-making waste. An effective process that is soon upgraded to separate coal from slag as well. This technological advance rouses the interest of the German Reichsbahn railway operator, who then becomes STEINERT's next corporate customer.

1987 – Eccentric non-ferrous separator

In 1987, STEINERT launches the first eccentric non-ferrous separator. It is used to recover non-ferrous metals such as aluminium, copper, magnesium and brass, and replaces the centric system. Once again, STEINERT proves to be a leading pioneer for an entire industry.

Late 1960s

At the end of the 1960s, STEINERT outranks its American competitors by developing an innovative product that makes it the world leader: the Anofol strip. While American companies used conventional copper coils, STEINERT is the first manufacturer to utilise anodised aluminium strips. The compact coil produced with this method is primarily characterised by an outstanding fill factor as well as excellent thermal conductivity. This innovation, which is also used in other industry sectors, marks another leap forward for STEINERT.

In the following years, the development and production processes continuously shift towards separation. 

1966 – The first suspension magnet

In 1966, STEINERT introduces the first suspension magnet for recovering iron from shredder material, household waste, construction waste, refuse and steel-making slag. Several thousand of these machines will be deployed worldwide in the coming years.

1963 – New lifting magnet series

With innovative new products, STEINERT quickly picks up on its success story following the post-war reconstruction years: In 1963, the company presents the prototype of a new lifting magnet series at its own booth at the Hanover Trade Fair. The advantages: lightweight, higher magnetic force, low price.

At the same time, the topics of waste processing and recycling are becoming increasingly more important in the 1960s. Dwindling resources, environmental protection requirements as well as exploding costs on the commodities market make new technologies essential. STEINERT consistently meets these challenges with great passion and a whole range of new products...

1931 – Birth of a strong company group

Julius Christian Buchholz acquires the 'Ferdinand STEINERT Elektromagnetische Aufbereitungsanlagen' company. The two companies are an optimal fit and are summarized under holding Metalloxyd. They further expand their market position during the next decades. The huge advantages of the cooperation become apparent in no time: The customers benefit from the bundled development expertise and strong synergies.

The merger yields a quick result with a breakthrough in the anodising process. STEINERT is the first company to use anodised aluminium conductors for manufacturing coils. The process is continuously improved over the next decades.

The company's site in Cologne was damaged extensively during World War II, but the management and employees are not disheartened by the outrages of the war: They make rapid progress on reconstruction and expand the product range. STEINERT also begins to establish itself more strongly on the international market.
