In 1936, a new building is erected in Remscheid-Güldenwerth, as there is hardly any space left on the site of the main plant in Remscheid-Vieringhausen. A site of around 40,000 square metres is acquired (today's HAZET Plant 1). All tools are now only supplied with the "HAZET" mark.
In 1938, Hans and Alfred Zerver become partners in the company. HAZET now has 14 domestic and 21 foreign representatives and takes part in trade fairs, e.g. the Leipzig Spring Trade Fair and the IAA in Berlin. HAZET is the first manufacturer in Europe to coat tools with nickel-chrome alloys, even before the Second World War.
