Zinc coating - Import export

At given need our experts can invoke extensive subcontracting.

In order to be able to benefit from the excellent strength values of carbon steels in a heavily corrosive environment – in comparison with expensive stainless steels – Zinc Lamella Coating can be used. Our Zinc Lamella Coating generates the so-called cathodic protection. The more ignoble zinc “sacrifices” itself to protect the base material. Steel can be protected in this way. The layer thickness is between 10 μm and 25 μm, for specific requirements thicker layers are possible. For metric threated parts it is necessary to meet the tolerances according to ISO 965, to avoid the screw thread‘s agglutination and to keep the friction coefficients accordingly adjustable. In contrast to paints, where the danger infiltration is given, this phenomenon is prevented through the „sacrificing“ impact of zinc. In salt spray tests zinc lamella coatings achieve better results than typical galvanic zinc plating, which often only reaches 96 h to 200 h in salt spraying tests (usually according...

"The zinc-nickel process has developed in recent years into a process providing one of the most efficient coatings in surface refinement, and is primarily used where high corrosion resistance at a high temperature load is required. Zinc-nickel alloys with 12-16% nickel content are very temperature-resistant, the higher level of hardness compared to the normal zinc coatings is also a very important property, since the risk of damage is lower. The process is related to the conventional alkaline zinc method, but has excellent durability even without post-treatment. This process is suitable for both barrel and rack goods."

"The alkaline zinc-iron alloy coating is very commonly applied to steel and ferrous materials. It has been used successfully for many years in the automotive and electrical industries, in equipment and mechanical engineering and also in sheet metal processing. It is characterised by a higher resistance to environmental influences. In addition to the classic galvanising process, the zinc-iron process provides a high degree of corrosion protection paired with an attractive surface design (black, silver), as well as uniform coating thickness distribution. This is a crucial advantage for workpieces with fit sizes. This process is suitable for both barrel and rack goods."
