1. Design

Customers rarely come with finished drawings we could work with. Our job is to work together to design the right product for the right use. In other words, we don’t just carry out the task given to us – we take responsibility for the functionality of the whole process, up to the functionality and delivery of the final product.
We study each customer’s material flows and overall processes. We evaluate different ways of implementing the task and draft a project plan based on our extensive expertise.

2. Welding

All stages of production are carried out in modern facilities, using cutting-edge tools and equipment. Each segment has its own top professionals, but our welding and finishing department plays an especially important role in terms of project functionality.

3. Machining

Siirtoruuvi has a long history and, although its business operations have expanded, developed and become more versatile, it still has the same mission: to provide high-quality machining services in a goal-oriented, customer-centred way.

4. Assembly, finishing

We can implement advanced configurations for our customers and produce products based on customer drawings via both component manufacturing and subcontracting.

5. Deliveries

We can implement large-scale projects, as we have four companies in the group to support our service segment. Together they form a manufacturing chain that reduces the customers’ needs to use multiple subcontractors. A comprehensive supplier is always a safer, faster and more durable option for the customer than a scattered system of various vendors.

6. Life Cycle Support

Expert aftermarket services bring important added value to our customers. Our spare parts services and supply of spare parts are independent of manufacturer, and our technical services include maintenance and repairs, device and condition assessments, and troubleshooting for all brands.
