About GFT Glüh- und Fügetechnik Bönen GmbH
GFT Glüh- und Fügetechnik Bönen GmbH was founded in 2001 and is a partner for heat treatment and thermal joining processes. Its core competence lies in brazing, hardening and annealing of components and assemblies made of steel, stainless steel and non-ferrous metals in belt through-feed furnaces, available 24 hours a day, seven days a week. In addition, since 2006 the company has manufactured underfloor heating, solar and geothermal manifolds in stainless steel with brazed construction, using a modular strip system from 2 to 16 heating circuits. Complementing this, complete assemblies made of sheet metal and tube are manufactured and components assembled. With around 60 employees at the Bönen site in North Rhine-Westphalia, GFT accompanies projects from the planning phase through to series production and primarily supplies the building services sector (heating, solar, geothermal). The company is certified to DIN EN ISO 9001:2015 (TÜV NORD).

Materials and processes
Steel
Base material for heat treatment and brazing of components and assemblies.
Stainless steel
Material of the underfloor heating and heating manifolds in brazed construction.
Non-ferrous metals
Non-ferrous metals for brazing and heat treatment.
Brass
Nickel-plated fittings of the manifolds.
Plastic
Heat-resistant, impact-resistant fittings of the manifolds.
EPDM
O-ring seals of the manifolds.
Brazing in belt through-feed furnaces
Thermal joining process in which brackets, sleeves or flanges are brazed in a single operation – free of stresses in the microstructure and free of intergranular corrosion.
Heat treatment
Hardening and annealing in belt through-feed furnaces.
