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 was an agent for Ramtec Finland in Northern China. In 2010, we established Ramtec CN in China to promote the Robi brand products of Ramtec Finland.
By 2013, Ramtec CN had set up its own manufacturing facility to innovate and produce hydraulic breakers and attachments under the Ramtec brand. While the two companies originally collaborated, their product lines have since diverged significantly.
The distinct products of both companies reflect their independent paths.
