Electro galvanised steel is carbon steel with a corrosion-resistant zinc coating applied to one or both of its sides by electro-deposition so the steel has higher corrosion resistance and higher performance.
The surface quality is exceptionally good for applications that require a high finish after painting, such as automotive exposed panels. The excellent control of the coating thickness that is achieved with the electrolytic deposition process is beneficial to enhance forming and joining operations, especially by contributing to more reliable results from automatic and robotic welding systems. Both the zinc and zinc-iron electrogalvanized coatings are readily paintable, but to achieve good resistance to corrosion, the coated-steel surface should be pretreated and primed prior to application of the finish paint coating.
TIASCO’s electro galvanized steel sheet and coil service capabilities include slitting, shearing, blanking, degreasing and brushing, stretcher levelling and metallurgical support.
The Benefits of Electro-Galvanised Steel
One advantage of Electro-Galvanised Steel is that it has a higher level of thickness control, which provides impressively accurate results. It is also ideal for making smaller components.
The finished product always has a shinier and more vibrant finish than the hot-dipped version. The sheet’s surface weldability is especially appreciated for spot and seam welds.
Impact Steel can offer you a strong and durable Electro-Galvanised product, appropriately suited to your construction or manufacturing projects.
Manufacture Process
Pretreatment
For the purpose of improving the adhesion to the plating, consisting of electrolytic cleaning to remove the surface contamination of the strip, pickling process for removing the oxide film
Electroplating
For the purpose of improving the adhesion to the plating, consisting of electrolytic cleaning to remove the surface contamination of the strip, pickling process for removing the oxide film
Post Treatment
With the manner of the electrolytic deposition of zinc ions on the surface of strip, consisting of CAROSEL Type of Main Equipment and Terne, Horizontal plating facility and conducting a duplex, differential plating and upstairs plating ect.
Electro Galvanized Steel Sheet Properties
The mechanical properties of electrogalvanized sheet are approximately the same as those for the equivalent grade (steel designation) of cold-rolled sheet because the steel coils are pre-annealed prior to processing on the electroplating line. For example, DDS cold-rolled sheet and DDS electrogalvanized sheet have similar mechanical properties. This does not mean that electrogalvanized product will behave similarly during stamping/drawing. The coating influences the behaviour during forming; thus, special practices are required when stamping electrogalvanized products. With the correct type of die material, clearances, etc., the stamping performance of the two products are similar.
- Uniform distribution of extremely thin zinc coating
- Spangle free
- Welds easily
- Good paintability
