GALVANISED STEEL COILS
Details:
The manufacturing process of galvanized steel coils involves several stages:
- *Material Preparation:*
– Raw steel coils are sourced and inspected for quality.
– The coils undergo a cleaning process to remove any impuriti contaminants.
- *Hot-Dip Galvanizing:*
– Coils are immersed in a bath of molten zinc, typically at a temperature around 450°C.
– The zinc coating bonds to the steel, providing corrosion resistance.
– This process is known as hot-dip galvanizing and ensures uniform coating
- *Cooling and Inspection:*
– The galvanized coils are cooled to solidify the zinc coating.
– Inspection is performed to check for uniformity, thickness, and adherence of the coating.
- *Skin Pass Rolling:*
– The coils may undergo a skin pass rolling process, which improves surface finish and flatness.
- *Chemical Treatment (Optional):*
– Some manufacturers apply passivation chemicals to enhance corrosion resistance and appearance.
- *Coil Cutting and Packaging:*
– The galvanized coils are cut into sheets or strips according to customer specifications.
– The final products are then packaged for shipment.
