Coating lines

ANDRITZ coating lines are well-known for their optimized line configuration, easy accommodation of product, and color changes.

Metal strip is coated using multi-layer technology to meet visual requirements on the one hand by applying different colors, and to protect the final product on the other hand against corrosion, chemicals, UV radiation, and mechanical scratches.

The final products of ANDRITZ coating lines are used for

  • can stock material (food and beverage cans)
  • the building industry (trapezoidal shapes, sandwich elements for roofs and walls, doors and gates, or ceiling elements)
  • household appliances (so-called white goods, such as refrigerators, freezers, stoves and ovens, washing machine shells)

Product description

ANDRITZ coating lines operate in a wide product range: The processed substrates can be uncoated carbon steel, hot-dip or electrolytic galvanized steel, or nonferrous material, especially aluminum.

As a first step, the material is pre-cleaned to ensure a uniform and clean substrate surface. Subsequently, the surface is activated by means of chromate-free conversion to obtain good corrosion protection and ensure that the subsequent prime coating adheres well. This can be applied either to the top and/or bottom surface. Before entering the next process step, the strip must be dried evenly.

For multi-layer coating, a finish coat can be applied on top of the prime coating layer (also to the top and/or bottom surface) to meet the highest quality demands on the final product.

Before final cooling, a device can be installed to apply a protective foil to the hot surface, depending on customers’ requirements.

Finally, the strip can be inspected in the inspection area and classified according to the customers’ specifications and the demands of the market.
