Our product range covers valves, penstocks, pipes and pipework parts. We are specialized in big valves (dia. up to 1200 mm). In our own pattern maker's shop we can prepare patterns exactly according to our customers' needs.
During the last decades Haapakosken Tehdas has become known as a manufacturer of cast iron and steel. We own and operate with the know-how the whole production chain from the pattern making, trough the foundry and machining shop to the assembling and shipping. This guarantees to customers flexible delivery and high quality of our products. We are running our production according to ISO 9002.
