E35 - Steels with Magnelis® zinc-aluminium-magnesium coating
This product is ideal for use in construction and civil engineering applications, where good corrosion resistance in very aggressive environments (e.g. chloride or highly alkaline) is required.
Magnelis® is a flat carbon steel product coated on both sides with a zinc-aluminium-magnesium alloy. This alloy, composed of 93.5% zinc, 3.5% aluminium and 3% magnesium, is applied by means of a continuous hot dip galvanising process. This optimum chemical composition has been selected to provide the best results in terms of corrosion resistance.
Magnelis® is available in a very wide range of steel grades: steels for cold forming and deep drawing applications, structural steels and High Strength Low Alloy steels.
Advantages
Thanks to its 3% magnesium content, Magnelis® offers self-healing on cut edges and superior corrosion resistance in chloride and ammonia atmospheres. This high corrosion resistance means that less metallic coating is required (weight reduction), which facilitates processing steps such as welding.
The zinc-rich metallic coating composition permits all the conventional processing operations possible with standard hot dip galvanised steel: bending, drawing, clinching, profiling, stamping, welding etc. The friction coefficient of Magnelis® coated steel is lower than that of standard hot dip galvanised steel, leading to reduced powdering during forming operations.
Applications
Magnelis® can be used in numerous industrial applications, such as:
Solar energy generation: structures for photovoltaic and thermal solar plants
Magnelis® is supplied passivated and/or oiled to temporarily limit any risk of white rust formation. During transport and storage, all necessary precautions must be taken to keep the material dry and to prevent the formation of condensation.
Forming
The forming techniques currently used for galvanised steel are also suitable for Magnelis®. Magnelis® behaves very well during profiling operations. The coating thickness must be compatible with both the desired degree of corrosion protection and the requirements of the forming processes envisaged. A minimum bending radius of 2x sheet thickness is recommended.
Weldability
In resistance spot welding, the welding current must be suitably regulated and regularly adjusted. Electrode life can be extended by regularly stepping up the welding current and periodically dressing (machining) the electrodes. The coating thickness must be compatible with both the desired degree of corrosion protection and the requirements of the welding processes envisaged. Magnelis® can be arc welded, laser welded, brazed or high frequency induction welded, taking the same precautions as with galvanised steel. For use in outdoor applications a reprotection of the weld seams from arc welding and high frequency induction welding is recommended.
