Valued aluminum coil coating line for aluminium coil
with foil rolls, rcuring furnace, etc.
Colour coated aluminium offers a multitude of different finishes by variation of coatings applied. These can be further enhanced with the introduction of metal embossing that presses a pattern into the surface of the coated aluminium. Whilst this can be used for aesthetic purposes, it also offers the advantage of increasing the materials rigidity. In certain applications, like roofing, this can increase the coated sheets load bearing capacity, allowing a lighter gauge embossed material to do the same job as a heavier gauge non-embossed product. It also covers minor surface defects that would be apparent on a flat sheet and result in a reject for visual reasons, therefore reducing line yield.
Lamination is often used as an alternative to colour coating / patterning, as it allows PVC, Polyester and PET films to be glued to the surface of the strip. These pre-painted laminates come in varying thicknesses and patterns. They can offer a greater scope of designs to that produced by painted pattern coating but for large volumes, costs can be higher than a standard pattern coating process.
Combinations of laminates with subsequent embossing can again produce varied and interesting effects that stimulate an architect’s imagination and it is these niche products that are gaining in popularity for both steel and aluminium coated products globally.
In Summary
Colour coated aluminium offers a versatile product for the construction industry. Equipment designs and supplier selection needs to be carefully considered, as this is a high value product being coated with expensive coatings and finishes. Incorrect line design can result in much lower production yields than predicted by creating high scrap levels or inability to process full product range. Lines can operate effectively, subject to market conditions, from 5,000 tonnes / annum up to 60,000 tonnes / annum. End users product demands are constantly changing, quality levels are being raised and therefore selection of the right plant and equipment will ensure aluminium coating lines sustainability into the future.
