    Excellent aluminum coil coating line

    Aluminium is a perfect substrate for colour coating, given its flat matt finish and high corrosion resistance. Aluminium consumption in the construction industry is growing, due to its weight differential compared to steel, making it suitable for long span roofing sheets, sandwich panels, composite panels and many other construction applications.

    Methods of coating aluminium for construction applications are typically similar to that of steel, however, the sensitive surface, soft alloys, different micro structure and conductivity means some subtle differences must be considered when designing equipment for coating aluminium. The points below are aimed at highlighting these requirements.


    Stitching / Slivers and Roll Cleaning
    As with all continuous process lines it is necessary to join the aluminium coils. To do this a mechanical stitcher is used (see Figure 1), however, unlike steel, aluminium is prone to creating slivers during the stitching process. Air blowing systems can reduce these and the level of carryover. It is however preferable that roll cleaning is also included throughout the line to reduce any further carryover along the line. Scraper blades applied to each roll on the entry accumulator tower provides a significant reduction in line contamination, however, individual roll cleaners on the covered bridle rolls optimises line cleanliness and performance on highest quality coatings.Both of these items can be retrofitted to existing lines where cleanliness is an issue.
