PARTNERSHIP & PROCESSES

A reliable supply chain in all situations

Surface treatment integrated directly into your production line

We are an integral part of your production chain. We can take full responsibility for surface treatment at your factory—as we did in Loimaa with Lännen Tractors—so your own team can focus on assembling multipurpose machines and special vehicles. We take care of quality, schedules and capacity for you.

Customised, tested coatings for demanding conditions

We develop and test coating solutions to meet the actual operating conditions your products face. Whether it’s our proprietary Piranha Stealth® stealth technology, abrasion resistance, or demanding field requirements for IR and CARC coatings, we verify performance using standardised stress tests at our Kaarina facility before production begins.

Production capacity for demand peaks, too

When order volumes grow rapidly, your own production won’t be held back by surface treatment. In addition to our Kaarina and Loimaa units, you can rely on the network of six factories across the Group. We can distribute workloads and flexibly scale production volumes without compromising quality or delivery times.

Traceability and documentation

The demanding defence industry requires complete traceability. We document every stage, from pretreatment and environmental measurements through to final inspection, in accordance with independent FROSIO standards, ensuring an unbroken audit trail.
