It is a new model metallic pipe on car piping system, which is of international advanced technology, high anti-corrosion performance and it also consistent with the international environmental requirements. It can support the severe molding operations during later assembling process period, without affecting the lifetime. The thickness of al-rich coating is 6-8 micron,which means there is no need to modify the size of the pipeline or the pipeline accessories , its color is silver.

Advantage: 1.Resistance to the corrosion of car fuel and brake oil

2.Even coating with the same color.    3. No chromium.

            4.Resistance to electrolysis and chemical perforation.   5.No coating lint.

           6.High elasticity also with the function of double metal corrosion protection

Coating antirust mechanism=sacrificial layer +blocked layer zinc-rich primer +Al-rich coating

Priming coat : Micron grade of zinc stacking.
