REFKO was founded in 1983 and during this time has established itself as an innovative, competitive and internationally recognised company in the refractories industry.

REFKO is a privately managed and family owned, medium-sized company. By listening to the wishes and needs of our customers and quickly responding to these we develop and provide customized solutions for their requirements.
Based in Ransbach, Germany we now operate on a global basis with international business partners for production, sales and service in Europe, South America and Southeast Asia.

Our first principal is to satisfy our customers with high quality refractory materials which can be handled without problems allowing them total confidence in our products. We aim to supply products which will permit our customers an increase in the quality of their end products and processes, improving operating reliability and, last but not least, reducing their manufacturing costs. Our commitment to these efforts are underlined  by our  adoption and implementation  of a successful quality management system formally accredited and certified to DIN ISO 9001 and the TÜV audit (Technical Inspection Authority).

The Refko product range covers all types of monolithic refractories as well as prefabricated refractory shapes.

Amongst the notable highlights of our range are:


  • The SUPERGUN series of low cement gunning materials;  combining the recognised  properties of LCC vibration castables  with the ease and convenience  of dry gunning installation
  • Spinel containing and spinel forming vibration and self-flowing castables for the monolithic working lining of steel casting ladles
  • The  CAST GUN series of high quality Shotcrete materials
  • Fused silica based materials  for both gunning and casting
  • High SIC content materials  for casting, gunning, patching and mortars
  • The ZSI series  of concretes and pre-shaped products for plants with a high consumption of alternative fuels
  • Insulating castables, gunning materials and pre-shaped blocks based on ultra lightweight micro-porous raw materials

In recent years as a direct response to our customers requirements REFKO has increasingly engaged in the engineering, construction and management of full refractory lining turn key installations.

Whilst traditionally our principal customers have been within  the iron  steel  and foundry industries for  several years we have also offered innovative solutions for the aluminium, non-ferrous metals and glass producers.

By applying our knowledge and expertise in refractory technology we have recently experienced a considerable increase in activities for customers who have to manage serious refractory problems caused by charging secondary fuels, e. g. the cement industry, waste incineration plants and biomass furnaces. For these applications we provide state of the art refractory products and construction concepts.

In clear words, the REFKO code of conduct codifies the values that REFKO upholds as a supplier, customer and employer and in turn, expects from its business partners.
