Grillo-ZEP® rods are newly developed lead-free zinc-based extrusion products. In order to ensure the range of applications for our Zinc Extrusion Products, we are continually developing alloy qualities to meet your special requirements. New zinc alloys are used allowing us to achieve mechanical properties which were not feasible with zinc material before. ZEP® is specifically produced from zinc and alloyed with copper, aluminium and magnesium. For example, it is thus possible to adjust defined tensile strengths which are in turn required to enable the forging and cutting of the material. Grillo-ZEP® products therefore often represent an alternative to non-ferrous metal or light metal rods generally used (e.g. brass semi-finished products or brass rods, copper semi-finished products or copper rods, aluminium semi-finished products or aluminium rods).

Company portrait

Founding fathers
Wilhelm Grillo was one of the founding fathers of industry in the Ruhr region. He was a man with enormous energy, visionary thinking and social involvement, and he started an impressive business development programme in 1842, when he was just 23. A hardware store in Mülheim an der Ruhr was followed by a zinc rolling mill in Duisburg-Neumühl in 1849. Only a few years later – in 1855 – he founded the first production plants for zinc oxide in Oberhausen, alongside two rolling mills and a gas production plant.

By the beginning of the Second World War, the company had developed into the largest zinc semi-finished product and zinc oxide manufacturer and SO2-supplier in Germany. After the wartime disruption of almost the entire production, an attempt was made with great difficulty to rebuild the production facilities – excluding the zinc smelting works. Aside from the development and expansion of its own plants, Grillo was involved in a multitude of companies. In 1974, after 120 years, Grillo withdrew completely from Oberhausen.

Since then, the focal points for the traditional Metal and Chemicals Divisions have been in Duisburg-Hamborn and in Frankfurt since 1997, with Goslar being the location for zinc oxide. RHEINZINK, co-founded by Grillo in 1966 and now a full subsidiary, has its rolling mill and administration located in Datteln and markets its zinc construction products through its own branches and/or companies on all continents.

Except for the period between 1988 and 1994, Grillo-Werke AG has always been 100% owned by the Grillo family, i.e. descendants of the company founder Wilhelm Grillo, who are still in charge of the company today.
