The Geomet® procedure
Thielco Steel Solutions Group is the only licence-holder in the Netherlands for the Geomet® chromium-free coating technology of N.O.F Metal Coatings Europe s.a.. This technology offers an environmentally-friendly alternative to the coating or galvanizing of smaller metal products - using solvents, mechanically or via electro-plating - particularly for the automotive industry. Thielco works for famous brands like BMW, Mercedes, Audi and Volkswagen.

A zinc-aluminium laminated coating is applied in a fully automated production line. This ensures extremely high corrosion resistance at a low layer thickness. A second important advantage is that hydrogen brittleness cannot occur. We can describe a product as a Geomet product once two layers have been applied because only then is the required protection offered. A third layer, the top coat, allows the product’s friction coefficient to be efficiently regulated. This is extremely important for various applications.

Thanks to these production lines, Thielco is able to offer a total package in Geomet 321 and Geomet 500 with various top coats. Products in all diameters up to and including M39 and grades of steel, with or without screw thread, up to a maximum length of 850 mm. This is unique for the whole of the Netherlands. The Geomet procedure is chromium-free and as such meets the most recent EU guidelines.
