Generally, coating heads are the same for colour coating of aluminium or steel. However, the high quality demands of the architectural aluminium products, which often request PVDF coatings dictates that 3 roll coating heads (with metering, pick up and applicator) are included. Flexibility in head design allows versatility in coating applications, ensuring forward coating / reverse coating, tray feeding and nip feeding to suit paint and required surface finish.

In recent times coated aluminium has become a choice material for decorative construction products, especially in curtain walling / cladding around new modern buildings. This has led to an increase in demand for patterns. Application of patterns using inks or paints with a protective clear coat can both differentiate the product and increase its use as a substitute for other materials. Woodgrain is the most common pattern,but increasingly the market is demanding other effects as producers’ look to create a niche product when compared with their competitors.

Aluminium coil pattern coating can be achieved by serveral different production techniques. Rotary screen print is one that offers flexibility of patterns but has a high investment cost requiring a high volume line / demand to justify this investment. Bronx uses a simpler process, as this can be readily integrated into new lines or retrofitted to existing coating technology at much lower costs than alternative processes, but still providing equivalent products.
