Steel protecion for all types of projects
Corrosion is a major problem for many sectors such as oil, gas, naval, petrochemistry industries, and civil engineering. Indeed, without protection, steel is attacked in most environments.
The ideal solution? Metallising using zinc or zinc-aluminium wire, which is, for steel, far better than any other corrosion protection system! Zinc or zinc-aluminium coating provides cathodic protection, and also plays the role of a physical barrier.
This is why zinc and zinc-aluminium metallising is used to protect steel in many applications.
Wind farms
For many years now, wind farms have multiplied on land and at sea. Green energy production has to be competitive, and thus required maintenance must be reduced as much as possible. Wind farms have to benefit from the protection of steel, so that they resist any environmental attack throughout their lifetime.
This is why zinc-aluminium metallising is used to protect the steel on wind turbines at sea (offshore), while pure zinc metallising is used to protect wind turbines on land (onshore).

Oil platforms
Oil platforms, and also the structures for producing green energy like electric boxes at sea, are living and working places for thousands of persons. These installations must therefore have their steel protected to last as long as possible in a proper condition, for economic reasons, yet even more so, for safety reasons.
Since the structures are in highly corrosive environments, zinc-aluminium coating prior to painting provides long-term protection for steel against corrosion.
Références
Bridges and viaducts
Bridges and viaducts are regularly exposed to high traffic. They are affected by collateral effects from exhaust gases, de-icing rock salt, and atmospheric conditions. Maintaining them takes time and closing them requires a complicated reorganisation of the road network.
Metallising using zinc wire or zinc-aluminium wire is an ideal process for efficient, lasting protection of their steel structures.
Références
Sea transport
Ships are particularly exposed to environmental attacks caused by moisture, salt and changes of temperature. The same applies to shipping containers, which are often handled very roughly. Several shipping companies have thus already used zinc-aluminium coating to prevent unexpected maintenance. The ideal solution for protecting steel and reducing long, expensive interventions to a minimum? A duplex system (zinc-aluminium coating + paints)!
Ground transport
Metallising using pure zinc or zinc-aluminium wire is widely used for protecting steel used in ground transportation. Several manufacturers are indeed offering for their haulier clients a high-quality product, by metallising the chassis of their trucks and buses. But containers also deserve efficient long-term protection of their steel. And for a few years now, even railway rails are treated by zinc coating!
Fences, gates and street furniture
Metallising is not exclusively reserved for protecting the steel of large structures. It is also a preferred solution for people looking for an efficient lasting protection for their fences, their garden furniture or their pergola.
Moreover, metallising is an ideal base for applying a powder paint and thus providing an aesthetic appearance. In the long run, this protection process for steel is also more economical! It does indeed eliminate the subsequent need for maintenance for decades.
Other steel constructions
More than for other steel structures, in this case, the aesthetic appearance has great importance. Zinc or zinc-aluminium coating will not only provide the structures with efficient, lasting protection against corrosion, but it will also serve as an ideal base for applying finish paints. The other advantage? In the long run, protection of steel by a duplex system (metallising + paints) is more economical than a traditional paint system!
Références
Farming equipment and heavy equipment
Purchasing farming equipment or heavy equipment is a considerable investment. To be cost-effective, machines have to be continuously used, without any interruption for maintenance. The best choice? A metallising + paint duplex solution. A metal coat will provide not only barrier protection, but also cathodic protection, even when the paint layer is very damaged.
Cast iron pipes
Cast iron pipes are difficult to replace and have to stay in place for a very long time, in spite of the corrosive environment they are faced with. Zinc or zinc aluminium coating provides you with a cold protection system which can easily be applied on cast iron. Combined with a paint coat, it will provide the corrosion protection they need throughout their lifetime.
Welding beads
Pipes are often made with galvanised steel, thus already being protected against corrosion by a zinc layer. At assembly, the protection is however interrupted at the welding bead. This is why zinc or zinc-aluminium coating is needed. This provides the pipe with uniform protection against corrosion.
Gas bottles
For purely psychological reasons, the consumer will always prefer a beautiful bottle to a rusted one.
Yet gas bottles regularly undergo impacts during transport, loading and unloading. Protection against corrosion has to be all the more efficient. The most suitable anti-corrosion system? A metallising + paint duplex system.
Capacitors
Capacitors consist of a polypropylene film wound around itself. The two ends of the capacitor are zinc coated, more generally with pure zinc in order to make electrical contact.
Electroplating
Zinc-plating is a term generally used for any surface treatment producing a zinc coating. Its purpose: to prevent corrosion damage to the metal. Zinc, as a highly reducing metal, will itself be oxidised instead of the metal it protects.
Electrolytic zinc-plating: zinc is deposited by electrolysis.
Stripping
Aluminium structures and galvanised steel structures do not withstand aggressive treatment. Peening using zinc shots is an excellent alternative here.
Glass industry
Certain types of glass are covered by a metallised film. In particular, this is the case of high-performance glazing: double glazing with heat-reflecting metal coating applied on the inside of a window. Result? Insulation five times better than with a single glazed window and two to three times better than a double-glazed window. And more: lower heating costs, greater comfort both during summer and winter, and no more cold sensation near the windows.
Mobile phones also are covered with a metallised film.
Electromagnetic shielding
Electromagnetic shielding consists of reducing the electromagnetic fields in the vicinity of an object by inserting a barrier between the source of the field and the object to protect. The barrier has to consist of an electrical conductor such as zinc. Since metallising is a cold process, there is no risk of deforming or damaging plastic cases.
