Electrical equipment is often at risk of oxidation due to the aggressive outdoor and indoor environments. This can be due to condensation in industrial or agricultural buildings, local conditions, the building’s location (marine or tropical) or climate. These factors can impact the structural integrity of electrical equipment, electrical safety, aesthetics, and the overall durability and lifetime of the system. Magnelis® is an effective answer to all of these challenges.

Magnelis® is an exceptional coating which provides breakthrough protection against corrosion for electrical equipment in many types of buildings including industrial, agricultural, commercial, data centres, hospitals, marine structures, warehouses, waste treatment centres, swimming pools and sports centres.

Magnelis® can be delivered according to EN 10346. It has similar electrical conductivity to galvanised steels and allows direct earthing contact. Magnelis® can be post-painted with similar painting processes to those used for galvanised steels.

Magnelis® is produced on a continuous hot dip galvanising line. The molten bath has a unique zinc-based chemical composition, wich includes 3.5% aluminium and 3% magnesium.

Thanks to its composition, Magnelis® provides an unprecedented level of surface and cut-edge protection, even in the most hostile environments.

Magnelis® for electrical equipmentHigh-level protection against corrosion

The coating for high strength steelsMagnelis® can be applied to a full range of high strength steels (HSS) with a yield strength of up to 700 MPa. HSS allow designers to create light and cost-effective structures. ArcelorMittal’s HyPer® range of HSS is fully compliant with Eurocode requirements and enables structural design to be optimised.ArcelorMittal has developed several tools to demonstrate the technical and cost-effective benefits of HSS for various load cases and configurations. Do not hesitate to contact us for more information.

The best alternative to post galvanisation• Cost reduction

(zinc, transport, manpower)• Simplified logistics and time saving• Better geometric tolerance for final

parts (especially thin gauges) as there is no deformation of the steel during the coating process

• Lower environmental impact• Smooth surface

Performance of Magnelis® in field testsSince 2012, more than a thousand Magnelis® samples have been exposed in a variety of different environments around the world for outdoor testing.

Every test has confirmed the optimal protection provided by Magnelis® against long-term corrosion. Magnelis® offers at least twice the corrosion resistance of galvanised steel in all types of environments. In very aggressive environments, the performance of Magnelis® is even higher.

Edge protection with self-healing effectTo create electrical equipment, steel sheets are cut, punched, and perforated. The self-healing effect of Magnelis® ensures that cut edges, scratches, and perforations are protected.

When exposed to the environment, Magnelis® forms a very dense, zinc-based protective film. This is unlike galvanised solutions where the film is very porous. The unique and dense Magnelis® film also forms on edges, welds, perforations, and scratches. If red rust is present on these uncoated zones, it will gradually be covered by a film of Magnelis®. The speed of this effect depends on the local environmental conditions.

It is almost impossible for the environment to penetrate this film. The result is perfect protection of the whole structure, even when the coating is damaged.* The speed of the self-healing may depend on the environment.

Magnelis® coating Initial exposure period (up to several weeks*)

The exposed cut end of the substrate is oxidised and forms red rust.

Subjected to rain and condensation (beyond several weeks*)

The zinc-based film (which contains magnesium) on the coating layer migrates over the cut end.

Advantages of using Magnelis® for electrical equipment

Cable managementCable trays and laddersProtective tubes

• Improved durability, especially in marine environments (offshore, ship, seashore, wind towers) or aggressive indoor environments (hot and humid industrial buildings, humid structures such as greenhouses and tunnels, and agricultural buildings with alkaline environments)

• Improved edge protection, for perforated parts in particular• Better behaviour in roll forming and bending operations

thanks to a low friction coefficient• Cost-effective solution compared to post-galvanised steel,

aluminium, or stainless steels.

Salt-spray test performance

Magnelis® is not yet included in the EN 61537 standard on ‘Cable management - Cable tray systems and cable ladder systems’.

However, ArcelorMittal has conducted salt spray tests of Magnelis® in accordance with the parameters of ISO 9227.

The results showed that Magnelis® ZM120 (10 µm coating per side), up to ZM430 (35 µm per side) is an efficient solution to meet the requirements of the standard (from Class 3 to 8). Solutions for some Class 9 requirements can be found.

• Improved durability in harsh outdoor environments, especially when located in marine areas.

• Improved durability in aggressive indoor environments (for example, industrial buildings with hot and humid atmospheres, agricultural buildings with alkaline environments, greenhouses, tunnels, swimming pools…)

• Reduction of maintenance costs thanks to- longer durability (for example, avoids maintenance at height

for lighting)- Better resistance to surface damage and scratches thanks to

the harder coating and self-healing effect.• Longer tooling lifetime and reduced maintenance in

manufacturing thanks to the harder coating and its lower friction coefficient.

• Compared with post-galvanisation:- Time- and cost-effective solution- Reduced part deformation- Better aesthetics

A certified solution ArcelorMittal’s Magnelis® coating is certified by independent bodies for its performance in protecting against corrosion. Certification has been received from:

• German Institute for Building Technology (DIBt)• French Scientific and Technical Centre for Building (CSTB)• Research Institutes of Sweden (RISE).

The durability of Magnelis® in various corrosion environments and categories has been certified by these organisations. DIBt has also validated the protection of cut edges by Magnelis® on substrates up to 6.0 mm thick (with ZM310 and ZM430). These edges do not need to be re-protected unless there are aesthetic requirements for the application. This makes Magnelis® a very attractive coating, especially for perforated parts and cable trays.

Reaction to fire Magnelis® is classified in the Eurocode classes A1 and A1FL for fire hazards. A declaration showing the performance of Magnelis® in a fire is available on demand.
