The protective coating on colour coated aluminium coils plays several main roles:


1. Protective coatings: During the manufacturing process of colour coated aluminium coils, one or more layers of coatings are formed on the surface, and these coatings usually have specific decorative, anti-corrosive and functional properties. The main role of the protective film is to protect these coatings from damage during transport, storage and construction.


2. Preventing scratches and contamination: During the handling and installation of colour coated aluminium coils, the surface of the coating can easily be scratched or contaminated due to a variety of factors (e.g. tools, dust, stains, etc.). Protective film can effectively prevent these external factors from causing damage to the coating.


3. Maintaining aesthetics: Protective films keep the surface of colour coated aluminium coils clean and aesthetically pleasing, preventing oxidation, discolouration or other forms of natural deterioration of the coated surface when exposed to air.


4. Increase durability: Some high-performance protective films are also UV and ageing resistant, further increasing the durability and service life of colour coated aluminium coils.


Overall, protective film on colour coated aluminium coils plays an important role in protecting the coating, preventing scratches and contamination, maintaining aesthetics and increasing durability. After the construction is completed, the protective film should be torn off in time so that the colour coated aluminium coil can give full play to its decorative and functional role.


There is no fixed number of days for the protective film to be removed from a colour coated aluminium coil after construction, as this depends on a number of factors, such as:


1. Construction environment: If the construction environment is harsh, such as dusty, windy or contaminated with chemicals, then the protective film may need to remain on for a longer period of time to protect the surface of the colour coated aluminium coil.


2. Post-construction clean-up: If a thorough clean-up is carried out immediately after construction and it is ensured that the surface of the colour coated aluminium coil is not contaminated or damaged, the protective film can be removed at the earliest opportunity.


3. Project requirements: Some projects may require the film to remain intact for a specific period of time to ensure that no damage is caused to the aluminium coils during subsequent construction or installation.


4. Type and quality of protective film: Different types and qualities of protective film have different durability and adhesion properties, so the time to remove them will vary.


5. Weather conditions: If the construction is carried out under high temperature, high humidity or dry environment, the performance of the protective film may be affected and the time of tear-off needs to be decided according to the actual situation.


Usually, it is recommended to tear off the protective film within a few days to a week after the construction is completed to ensure that the surface of the colour coated aluminium coil is fully protected. However, the exact time to remove the film should be determined according to the actual situation and advice should be sought from the supplier or manufacturer prior to construction. If the protective film cannot be removed within a period of time, it may be necessary to use specialist tools or chemical solvents to assist in the removal of the film, but please be sure to follow the relevant safety procedures.
