Our engineers design wheels based on European and global ETRTO, EUWA and TRA standards.

We create a wheel design in 3D to evaluate its appearance and technical parameters.

We order steel from reliable suppliers – U.S. Steel and ArcelorMittal.

We store steel in our own steel warehouse in Narew, where we cut the material to the appropriate size in preparation for further processing during production.

We create bare rims with thickness of up to 10 mm and a width of up to 44 inches on the production lines for profiling bare rims designed and produced at PRONAR.

Pronar factory in Narewka cuts and stamps wheel discs.

Steel wheels, discs and bare rims are welded  by our welding robots. Thanks to them we can maintain the highest repeatability of our wheels.

The welded wheels are passed to the paint shop. Here, first of all, we secure their surface using modern and ecological solutions – nanoceramics and cataphoresis. This combination guarantees high corrosion resistance and excellent surface preparation for painting.

The wheels are powder coated on our automated painting line. We offer clients a full range of RAL colours, including special colours.

Before the wheels reach customers, we conduct a number of trials and tests in our Research and Development Center and independent laboratories with which we cooperate. The checks include: FEM (MES) computer analysis, load-driving simulation, cornering simulation, testing of chemical composition, hardness, impact strength and fatigue life of steel, micro- and macroscopic tests, ultrasonic and X-ray tests, and tests of paint coating durability in a salt chamber climate.
