FAQ :
Question A : There is also a Ramtec Robi in Finland, what is the relationship between Ramtec CN and the one Finland ?
Answer A : Originally, Ramtec CN served as a regional agent for Ramtec Finland in Northern China. In 2010, leveraging our expertise as an agent,
we took a bold step by founding Ramtec CN to champion the promotion of Robi brand products from Ramtec Finland. By 2013, Ramtec CN
had evolved to establish its own manufacturing facilities, delving into the research and creation of hydraulic breakers and
attachments, heralding the inception of the Ramtec brand series. While our collaboration with Ramtec Finland was significant, both
companies have since pursued distinct paths, focusing on different product innovations.
