Color Coated Galvanized/ Galvalume steel Coil (PPGI /PPGL)
Color coated steel plate is a new construction material which is growing rapidly all over the world in recent years. It is on a continuous set of chemical process, after coating and painting and come into final products. The painting quality is ore well-distributed, more stable and more ideal than painting directly on the single metal structural surface.
The color coated steel plate has good decorative, forming property, anti-corrossion and strong adhesive. The color can last for long time. As the color coated steel plate can take place of wood, prossesses good economic efforts like fast construction, energy saving, anti pollution, it has become an ideal construction material nowadays.

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.
Application
Pre-painted Galvanized/Galvalume Steel are used in roof structure, surface sheet of balcony, frame of window, folding screen and electrical equipment. Pre-painted steel can be formed into almost any shape, and it has excellent resistance to weathering, superior longevity and texture options.

Quality control
• Surface test.
• Salt spray test is srtificial salt spray environment ,simulate marine climate ,used o check Anti salt spray corrosion performance of GI and PPGI ,and evaluate the quality of the protective coating process.
• Flexibility Impact Tester Used to assess catsuit coating at a very fst deformation ablility to resist cracking or fall out.
• Coating cup drawing tester Used to assess catsuit slow deformation under coating ability to resist cracking or fall out.
• Zinc layer test
Our Min Zinc and AZ layer is 30g /m2 .We focus on middle and high quality product only.
