TDC International AG (TDCI) is headquartered in Switzerland with a production facility in Germany specializing in various specialty industrial constructions using glass fibre reinforced plastics (GRP). Our German subsidiary, TDC Technical Duroplastic Constructions GmbH has been an expert in GRP fabrication since the 1990s.

We specialize in the fabrication of pipeline coatings, glass fibre tanks, glass fibre linings for tanks and basins, glass fibre covers, glass fibre mouldings and many other specialty products (e.g. motorway shock-absorbing impact barriers) tailored to each customer’s unique requirement. Given the application flexibility and the resilient features of the raw materials of our products, TDCI services a variety of industrial customers across a wide spectrum of industries, including energy and pipeline infrastructure, electricity and gas utilities, water and waste water, chemicals, agriculture, transportation, and many others.

Over the years, we have built a wide customer base consisting of large European utilities, network operators, steel mills, transportation companies, municipalities, and well-known German chemical companies. We continue to expand our customer base, providing products and services in Europe and beyond.

Our know-how, craftsmanship, and proprietary methodologies allow us to provide our customers consistently with high quality manufacturing and hence we stand out among our competitors. The uniqueness of our diverse product offerings for specialty constructions also gives us a strong foothold in the industry. We work closely with our customers to find the optimal product solution for their needs, including assistance on the engineering and design.

Achieving consistent high quality on our products is something we are proud of. Our production team is extremely well-trained with skilled craftsmanship. We have adopted a stringent and thorough quality control protocol to ensure our manufacturing procedures and final products adhere to our customers’ full satisfaction.

Glass-Fibre Reinforced Plastics

Glass-fibre reinforced plastic (GRP), also called fibre glass, is a composite typically made of polyester resins and glass fibres. The strands of fibres allow the material to be strong along their longitudinal axis. The individual components of the material can be processed in such a way that the product properties can be flexibly formulated into practically any requirements.

This material offers many convincing advantages. GRP can be stronger than metal, wood, concrete or ceramic materials while at the same time being lighter in weight. One of the key features of GRP is its extreme corrosion-resistant characteristic. Other important advantages of GRP include its good resilience to chemicals, high temperature, mechanical scratches, good insulating properties, excellent weather resistance and low thermal conductivity. With this material, the engineering team has great design flexibility in the application and moulding process.

GRP also serves as a load-bearing construction material in a wide spectrum of areas. Together with its classical applications in shipbuilding, automobile manufacturing and aircraft construction, in recent years GRP has also become an established product in the various other building and construction industries.

Key features of GRP are:

  • Resistance to chemical corrosion
  • Protection from mechanical abrasion
  • Resilient to extreme temperature ranges
  • Protection from wear and tear
  • Material strength and long lasting
  • Non-Conductive
