The Key flag symbol – a promise of genuine Finnish origin

Woikoski’s gases and services have been awarded the Key Flag. It is a symbol of Finnish quality, work and responsibility – values we have cherished for over a century.
The Key Flag Symbol is granted to companies that meet strict criteria for domestic production and responsible operations. To receive it, production must take place mainly in Finland, and the company must contribute to Finnish employment. We are proud that the majority of our gases carry the Key Flag symbol. They are produced in Finland, with Finnish expertise.
Woikoski Oy is a Finnish family-owned company that has been serving domestic industry since 1882. Over four generations, we have grown into a strong expert in the gas sector and a trusted partner. We manufacture high‑quality products, provide professional service and ensure smooth deliveries across Finland through our extensive reseller network.
For us, long-term commitment matters. We are not looking for quick wins – we are building a sustainable future responsibly, through Finnish work and in line with the values of the Key Flag Symbol.
Finnish expertise
We want to ensure that Finnish work stays in Finland. Around 200 professionals from various fields work at Woikoski across five locations, each contributing to a long tradition of domestic craftsmanship.
Finnish expertise is visible in everything we do – from production to customer service and from product development to safety. We want to offer workplaces where expertise grows and where Finnish industrial skills can truly shine.
When customers choose Woikoski, they also support Finnish work and the values represented by the Key Flag Symbol.
Does it carry the Key Flag Symbol? – We do.

“We believe it is important to help create wellbeing in Finland through employment and taxation. Especially in these critical times, we feel a strong sense of responsibility and purpose: it is the entrepreneur’s willingness to take risks that keeps Finland’s economy running, as we create jobs and generate tax revenue that sustains our society.
In turn, it is the responsibility of Finnish consumers to keep domestic companies thriving by choosing Finnish products. Only in this way can we safeguard Finland’s self‑sufficiency.”
Let’s keep Finland moving forward – together!
