Appearance Advantages
- High flatness: the surface is flat and smooth, without obvious defects such as unevenness, wavy deformation, indentation or bulging. Whether observed with the naked eye or touched by hand, you can feel the evenness and flatness of the surface. In the subsequent processing, such as bending, stamping, etc., the colour coated aluminium coil with high flatness will not be ruptured or deformed due to uneven stress.
- Uniformity of colour: The colour is uniform and consistent, with no obvious colour difference. Whether it is different parts of the same roll of colour coated aluminium coil, or between different batches of production of colour coated aluminium coil, the colour should maintain a high degree of consistency. A quality colour coating process ensures that the pigments adhere evenly to the surface of the aluminium coil, resulting in vibrant, bright and long-lasting colours.
- Strong coating adhesion: good adhesion between the coating and the aluminium coil substrate makes it difficult for the coating to flake, peel or lose paint. The adhesion of the coating can be examined by simple scratching test or tape sticking test, i.e., use a razor blade to scratch on the surface of the coating, then stick and tear off the tape and observe whether the coating is brought up by the tape or not.
Performance Advantages
- Good weather resistance: it can withstand long-term sunshine, rain, wind and other natural environments, and is not easy to fade, discolouration, chalking and other phenomena. In outdoor use, weathering good colour coated aluminium coil can maintain the beauty and performance for a longer period of time. For example, colour coated aluminium coils coated with high-quality polyester paint or fluorocarbon paint have good weather resistance, and the warranty period can reach 10 years and 20 years respectively.
- Strong corrosion resistance: it can resist the erosion of acids, alkalis, salts and other chemicals, and is not easy to corrode in harsh environments. This is especially important for colour coated aluminium coils used in corrosive environments such as seashores and chemical parks. High-quality colour coated aluminium coils undergo special surface treatments during production, such as passivation and phosphating, to improve their corrosion resistance.
- Excellent mechanical properties: it has good bending and bending strength and toughness, and is able to withstand certain external impacts and deformations without rupture or damage. For example, in the building curtain wall, roof and other application scenarios, the colour coated aluminium coil needs to have enough mechanical strength to resist wind pressure, snow pressure and other loads.
- Good fire performance: it has a certain fire performance, which can play a certain flame retardant role in the event of fire and reduce the spread of fire and hazards. The colour coated aluminium coil that meets the relevant national standards, its fire rating should meet certain requirements.
Environmental protection
- Recyclability: aluminium is a recyclable metal material, good quality colour coated aluminium coil can be conveniently recycled and reused at the end of its service life, reducing waste of resources and environmental pollution.
