Z60 PPGI PPGL Coil KCC/Nippon Paint Color Coils Pre-Painted Steel Coil GB/T2518-2004
Prepainted steel coil, also known as color coated steel plate, is steel plate that has been surface treated and coated. It features bright colors, strong decorative effect and long service life. It is widely used in the construction industry, especially as roofing panels and exterior wall cladding.
The substrate of prepainted steel coil is usually selected from galvanized steel sheet, Galvalume sheet or cold rolled sheet.
After strict surface treatment and pretreatment, it is coated with high-performance polyester or reflective paint to form coatings with various colors and effects.
This coating has the characteristics of bright colors, small color difference, as well as certain hardness and toughness.
It can resist certain external forces and environmental erosion, and has a service life of 15-20 years.
Compared with traditional paint coating, prepainted steel coil has the advantages of simple construction, easy control of moisture, and less environmental pollution during production.
It not only has a good decorative effect, but also has a fast construction speed, which can greatly improve the construction efficiency and quality of building projects.
At the same time, since the surface treatment and coating are completed in the factory, the product quality is more stable, which also reduces the difficulty of on-site construction.The selection of prepainted steel coil should be based on the actual use environment and requirements.
For roofing panels and exterior walls, weather resistance, color stability and constructability should be considered.Manufacturers, substrates and paint brands are also important references.
The product should be stored in a cool and ventilated environment, avoiding long-term sun exposure and rain, in order to ensure the best performance.
In summary, prepainted steel coil is a high-performance and highly decorative building material.
It is favored by many consumers for its excellent comprehensive performance, and has a wide range of applications in the modern construction field. I believe that with technological progress, the color options and surface functional treatments of prepainted steel coil will be enriched, and the application range will be broader.

Production core strengths | |||
Resistance to acid rain: | |||
Coating protection mechanism: It is very easy to form acid rain in the high level of industrial emissions or pollutants environment. Acidic penetration is formed in the surface of pre-painted steel, and accelerates the corrosion, forming blistering, peeling and so on. | |||
Resistance ultraviolet rays: | |||
Coating protecting Mechanism: pre-painted sheet in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and loss of gloss, lose paint quickly. | |||
Resistance to humid heat: | |||
Coating protecting mechanism: in hot and humid environments, high osmotic pressure of water vapor accelerates penetration, forming the degeneration of painting film, then the corrosion of the substrate, with the phenomenon of bubbles and peeling. | |||
Resistance to low temperature: | |||
Coating protecting mechanisms: most of the paint can keep stable processing performance above 0 degree, but at alpine region, the temperature will be below 20-40 degree, normal paint will become brittle,bend cracking, or even lose paint, thus protection function is lost totally. |
