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. |
Pre-painted metal is a metal on which a material such as paint has
been applied by the coil coating process to form a
protective film. Coil coating is a continuous process in which a
coil of metal (steel or aluminum are common substrates)
is unwound and both the top and bottom surfaces are cleaned,
chemically treated, and then primed and /or painted and
oven cured. A wide range of coatings are in use, developed in order
to provide different levels of durability and performance and to
satisfy distinct aesthetic requirements.
Applications of Prepainted steel coil
1. Construction and building: roofing; ventilating duct; handrail;
partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator;
DVD;etc.
3. Transportation: oil tank; road sign; etc.
4. Agriculture:barn; etc.
5. Others:vending machine; game machine; etc.
Quality Control:
The pre-painted galvanized steel coils are a product obtained by
subjecting a hot-dipped galvanized steel sheet to a surface
chemical treatment, applying organic coating on the surface,
followed by baking and curing.
PPGI steel coil is a popular material for roofing sheets, wall
panels, furniture, home appliances, automobile uses, etc. It keeps
the strength of galvanized steel. Meanwhile, the organic coating
offers various colors and attractive appearance.
FAQ:
Q: Can you send samples?
A: We can send samples to you, our samples are free, but customers
need to bear the courier cost.
Q: What are the certifications for your products?
A: We have ISO 9001, SGS, SABER, SONCAP etc certificate.
Q: How long does your delivery time ?
A: Generally, our delivery time is within 20 days.
Q: How about the packages ?
Normally, 3 layers water proof standard export package.
Special packaging includes vertical packaging or customer request
packaging. This packaging method can calculate the price according
to the packaging cost. Vertical packaging is the roll core up and
the bottom fixed on a wooden pallet. This packaging method
maximizes the protection of the steel coil from external forces,
but the packaging cost and labor cost are high.
