- We blast products with steel grit to Sa2.5
- We blast stainless steel and aluminium parts with glass beads
Powdered products are spray-degreased and phosphated in 3 to 6 technological steps according to the different product use (interior, exterior, wet environment) and according to different materials.
- Phosphating with passivation by spraying on a 6-step pre-treatment line with a pre-treatment length of 60 metres suitable for exteriors
- Spray phosphating on a 4-step pre-treatment line with a length of 18 metres
- Phosphating of large-size parts with 3-step pre-treatment in a spraying machine with passivation
- Products after pre-treatment are dried at 110–125 °C in the final step
Zinc phosphate or iron phosphate can be used
We zinc-plate base material, steel and cast iron. The electroplated zinc coating in weak acid zinc baths can be:
- without passivation (under cataphoretic coating)
- with passivation, by blue trivalent chromate + sealing with transparent paint
- with passivation, by yellow hexavalent chromate + sealing with transparent paint
- with passivation, by black trivalent chromate + sealing with transparent paint
- thick-layer passivation by trivalent chromate + sealing with transparent paint
Coating thickness up to 25 µm zinc. The maximum dimensions of plated parts are 2,000 × 1,000 × 250 mm, the maximum length of bar materials is 2,200 mm, weight up to 100 kg.
We also offer:
- alloy plating (Zn - Ni),
- cataphoretic coating:
Standard coating thickness: 15–35 µm Maximum part dimensions: 1,500 × 500 × 1,500 mm (h × w × l) Maximum part weight: 50 kg Maximum baking temperature: 170–235 °C
- Hot-dip galvanizing
After immersion in a zinc bath, an intermetallic phase of iron and zinc is formed on the surface of the material.
The thickness of this layer varies between 50–190 microns depending on the chemical composition of the material, its shape and the immersion time. We can also galvanize large steel parts.
