Zinc coating - Import export

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...

Easy-Click closure - stop-it can be opened and closed in any position - without tiresome screwing on and off. High quality material - stop-it made from the heat resistant and chemical resistant plastic PVDF. The clamp is galvanised steel. The hose clip can be used wherever the flow in hoses with liquids or gases needs to be regulated or stopped. Stepless flow regulation: With the hose clip stop-it's knurled screw, a stepless, delicate flow regulation or complete stop of the flow are possible, even for existing hose connections. The hose is compressed over a wide area against the sturdy steel hook in order to prevent it from being damaged.

"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."

KEIPER timing belt clamping plates can be made of many different materials, e.g. aluminum, steel or stainless steel. Keiper can produce them in all pitches and designed according to your specifications and drawings. This means that you will receive the optimal solution for the intended application and load. Our timing belt clamping plates work together optimally with our extensive and complete range of timing belts: in other words, a perfectly matched system for your requirements. We also have a large number of standard aluminum clamping plates on stock, which can be reworked according to your specifications (e.g. bores and mechanical processing based on drawings). Furthermore, such special surface coatings as hard coating, anodizing, zinc coating or bronzing improve the corrosion and wear resistance.

SEPA EUROPE, the experts for customized cooling solutions meets the highest expectations with its wide range of guards for axial fans. Modern high-performance fans operate at high speeds which increase the risk of injury. To enhance safety, SEPA EUROPE offers guards for axial fans in every required dimension. The well-designed guards of SEPA EUROPE are not only extremely stable but also improve the appearance of each fan. The high-quality surface (chrome-plated, powder-coated, zinc-plated or pure stainless steel V2A or V4A) stands for a longer service life and extensive protection against corrosion. We perfect the product with excellent finishing and a flawless surface without sharp edges. Additional advantage: The guards of SEPA EUROPE are aerodynamically optimized so that the fans can operate with optimum efficiency. A further advantage is the simple mounting by screwing to the fan.
