Thank you for visiting our homepage
Starting as a metal polishing shop founded by my grandfather in 1963, our family business has since grown for three generations.
In 1988, we integrated our many years of metal polishing skills to precision sheet metal processing to satisfy progressing requirements of our clients.

Having pride in our skills and being alert to innovation and change, we have integrated generations of know-hows with the latest technologies to guarantee quality and satisfaction for our clients.
Our goal is to continue to improve our skills and to produce better products in a shorter amount of time.
