Design Services

Design, manufacturing, sourcing and logistics – everything under one roof.

Contact us

We implement electrical, wiring harnesses, sheet metal, and electronics design services for our customers on a turnkey basis.

Each design project is individually defined and custom dimensioned for the customer – we design both limited parts and complete systems.

We have at our disposal the latest design tools, which we continually develop in accordance with our customer needs. A flexible use of resources in our design projects is made possible through our network.

Our design projects are always fully confidential. Our design facilities have limited access only to participating designers and company management. This ensures the safety of all design projects.

With the help of Autocad, we design the various thin sheet metals that are needed as part of the larger assemblies. Our logistics specialists conduct competitive bidding on the production of the sheet metal from our reliable subcontractors.


The electronics parts and circuit boards in our products are always designed as part of the product assembly. A complete plan designed by Arr-Systems Oy is provided to our customers.

Take advantage of our comprehensive experience

Arr-Systems Oy has experience in a wide range of design projects. With the comprehensive expertise and know-how of our engineers, we bring new insights and innovations that improve the usability of our products and enhance their reliability.


Our production covers the wiring harnesses and various accompanying mechanical assemblies and system deliveries. We utilise state-of-the-art automation machines for small and medium-sized wiring needs.


Our various maintenance and repair services are increasingly becoming an integral part of our engineering operations. Therefore, Arr-Systems Oy can help its customers take care of their own respective customers even after the transaction is complete.

We always create the necessary operating and spare part manuals, as well as step-by-step assembly images for our production. Upon request, manuals can be provided that are translated into several languages. This ensures that you can use our documentation in the best possible way as a part of your own services.
