Leinolat & Kumpp was founded in 1962, originally as a tinsmith workshop consisting of two men. In the 1970s, Leinolat & Kumpp became Leinolat Oy and investments were made in new operating premises and machinery. At that time, the company started to design and manufacture ventilation solutions for public facilities and residential buildings.

The organization developed by networking with other operators. Cooperation with outside professionals taught Leinolat Oy to appreciate the valuable skills of different parties and the benefits of close cooperation with our customers.

In the 2000s, Leinolat Oy continued its development. The company grew through acquisitions, evolving into Leinolat Group.

Today, Leinolat Group consists of six companies serving global machine and equipment manufacturers, shipbuilding, energy production, oil, gas, and automotive industry - as well as HVAC and process companies around the world.

All the companies in Leinolat Group have extensive experience, solid professional skills, expertise in machining and a wide array of services in the metal working industry.
