FAQ :
Question A : There is also a Ramtec Robi in Finland, what is the relationship between Ramtec CN and the one in Finland?
Answer A : Originally, Ramtec CN began as an agent for Ramtec Finland in Northern China. In 2010, we registered Ramtec CN to promote Ramtec Finland's Robi brand products.
Through this partnership, we established Ramtec CN in China, dedicated to showcasing Robi brand products. By 2013, Ramtec CN developed its own manufacturing facility, pioneering in the research and creation of hydraulic breakers and
attachments. This venture led to the inception of our own Ramtec brand series. While the companies once shared a collaborative relationship, today, their product offerings have diverged dramatically.
Both entities have evolved; the products they produce now bear distinct differences.
Ramtec Finland specializes in the Robi brand, distinct from Ramtec China's exclusive Ramtec brand.
