Color Coated Pre-painted Steel Coil (PPGI | PPGL)

The properties of Color Coated Steel are tough coating, completed protection, low maintenance and long life.

Pre-painted Galvanized/Galvalume Steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.

Product Specification

Production core strengths

l 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.

l 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.

l 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.

l 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 test

• Surface Test.

• Cupping test.

    The coating cup drawing tester Used to assess catsuit slow deformation under coating ability to resist cracking or fall out .

    The cupping test is a test method applied in the metalworking industry and is used to determine the ductility of sheet metals and strips.

    For the performance of cupping tests on sheet metal a spherical drawing punch is pressed

into a clamped metal sheet until a crack appears. The cupping test is used to assess drawing formability.

• Flexibility Impact Tester  Used to assess catsuit coating at a very fst deformation ablility to resist cracking or fall out .

• Hardness tester and Tensional test .

. 

• Coating thickness measuremen

• MEK test is in follow Video .

• Gloss meter 

Gloss Meter will measure the gloss of a surface where an aesthetic appearance of the coating finish is required.

• 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  .    

    A salt spray test is a corrosion testing method that uses high-saline environments to measure the corrosion resistance of products, paints and coatings over extended periods.
