Technical information

Own production – galvanised repair parts
To keep up with car manufacturers’ increasing use of galvanised steel, we are introducing repair parts in galvanised plating.

We will maintain the highest quality finish in the embossing and edges of the part. Therefore, we have chosen a plate type that has the optimal combination of thickness of zinc coating and malleability. It also offers excellent adhesion when painted.

The technical name is DX54D 140Z MB and it is a high-quality hot-dip galvanised (zinc-coated) plate. The galvanised coating contains 99% pure lead-free zinc. Our new galvanised parts have undergone rigorous testing to ensure the plate’s weldability and surface adhesion of spray paint and top coat.

Own production – black repair parts
Our steel repair parts undergo extensive surface treatments that ensure a perfect surface for further processing.

The surface treatment for our black repair parts consists of:

• Raw material: Cold rolled steel size 14.03 DIN 1623 tolerance: DIN 1541.

• Degreasing: Degreasing uses an acidic combination product at 45% for a metallic clean and dust-free surface.

• Phosphating: Phosphating 0.6-1.0 g/m2 surface. DIN 50942, Feph r a US Fed. TT-C-490 B, type 2.

• Flushing/passivating: 2-step cascade flushing (max. 500 microsiemens/cm2).

• Drying: Tunnel oven at 120 degrees.

• Painting: Computer-assisted parts scanning. Electrostatic spraying with water-based hydrofiller on an Alkyd-Melamine base.

• Drying: Flash-off zone. 10 minutes at 40 degrees.

• Hardening: Tunnel oven. 20 minutes at 145 degrees.

• Preparation: Before spray painting, gloss must only be taken off with fine sandpaper, after which the spray paint and top coat can be applied.
