A Letter from our Chairman, Matti Arpiainen

Certified For Your Benefit

We are certified, for example with ISO 9001 (Quality), ISO 14001 (Environmental) and ISO 45001 (Work Safety and Reliability) Certificates.

For our customer it means that we are committed in building, developing and maintaining high standards when it comes to leading and developing our business and its values.

We believe in fighting for a safer industry. For us it’s important to be able to offer our customers better overall services also by keeping our employees safe.

For the last few years we have been investing heavily in developing our company’s HSE (Health, Safety and Environment) actions. For us HSE is not just about the certificates — it’s a wholesome way of life — that we live by everyday.

On top of our own industry’s certificates we can and have been serving by the required standards of other industries. For example, the TS16949 certificate often required by the automotive industry is something that we already act by with some of our global clients. When it comes to PPAP and APQP-processes and documenting, we already do so too.

We also already act by the requirements of the Danish and Norwegian offshore industry by being part of their industry ecosystem. We also have the Russian GOST and Rostehnadzor certificates as we have been importing to Russia for quite a long time already.

As you can see, we are more than committed in serving different industries by acting according the different quality, environmental and safety standards and other requirements.

To keep up with the demands, we are continuously training our staff and keeping our eyes open for what the future holds. All, so we can service you, our customer, in better and more wholesome ways now and in the future.

Yours Sincerely,

Matti Arpiainen
