Traditional welding services

Although we offer many special services, such as submersible sparkling and wire sawing, traditional welding work has always been at the heart of our operations. Our assignments include a wide range of products, the joints of which are made, for example, by TIG and MIG or MAG welding. So you can take advantage of our expertise and order only welds from us!

Painting services for metal products

You can also get versatile painting services for various metal pieces from Metalli & Koneistus Keränen Oy. We have a wide range of paints and techniques to choose from, depending on the properties you want for the finished product.


The paint can produce various properties such as corrosion resistance, longer life and better appearance. To ensure a successful end result, we always carry out pre-treatment, such as shot blasting, chemical treatment, washing or grinding, before the actual painting.
