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 was an agent for Ramtec Finland in Northern China. In 2010, as one of their representatives,
we established Ramtec CN in China to promote Robi brand products from Ramtec Finland. By 2013, Ramtec CN launched its manufacturing
factory and embarked on developing its own line of hydraulic breakers and
attachments, introducing the Ramtec brand. Although we once cooperated, our current product lines are distinct and separate.
The two companies now operate independently, offering entirely different products.
