Swiss quality

A bending and straightening machine must be perfectly constructed and welded so that it can withstand the demands placed on it over a long service life. A great deal of expertise lies behind that. We have acquired this knowledge over decades. The latest straightening and bending technology is being developed continuously in the company.
