Company

A key player in the glass industry

Coming from a great tradition, heading for the future.

High-tech and precision from design to the finished machines: CNUD EFCO GFT has been manufacturing annealing lehrs, tin baths and accessories for the float glass industry since 1957. The company has sites in Belgium, Germany, Romania, and China and has already been involved in equipping more than 300 float glass production lines around the world.

Our history

United power to create new synergies.

CNUD EFCO GFT was born of a merger between three pioneering companies – CNUD, EFCO and GFT:

  • CNUD, an expert in annealing lehrs, has spearheaded the annealing lehr production process since the dawn of float line history.
  • EFCO has delivered ground-breaking work in tin bath development, with a special focus on the tin bath roof.
  • GFT has also developed expertise in tin bath production since 2005.

Since the end of 2019, CNUD EFCO GFT has been a member of the international Grenzebach Group. With Grenzebach, a global player, CNUD EFCO GFT can access an enormous additional wealth of knowledge and provide even more comprehensive solutions and services for the glass production industry.
