PPGI Pre-painted Galvanized Steel Coil Z275
- Metal Roofing Sheets for Building Construction
Product Description:
Pre-painted steel products play an important role in the steel structured construction. And the raw
material used for Sunrise products are all from the best plants in the world. And Strict endurance
tests have been done to ensure the quality for product life and meet the requirements by state.
Pre-painted steel is anew building material. No pollution is its main feature. Also, it can be reducing
the cost and staff, shorten the work times by using this kind of building mateials, so it has the high
efficiency.
Pre-painted steel is applied to building construction, home applicances like air conditioning, washing
machine, etc, and industrial maching for its fine weathering resistance, corrosion resistance, high
ability of machining and beautiful semblance.
Users can select proper paint for colored band like polyester silicon modified polyester,
polyoxyethylene plastic collosol, poly (vinylidenne fluoride) and so on according to their
application conditions. Pre-painted steel is going to replace wood and other material
with its special advantages, such as: avoiding discoloration, climate tolerance and
anti-powdering. It reduces most of the maintenance charge. At the same time, the various
of colors and the special surface coating and structure endow pre-painted steel a great
mobility and plasticity in every application area.
In china, construction is the main application area of pre-painted steel. At the same time,
as its advantages being known and the technology improving day by day, it is not only well
used in steel producing area, but also accepted by car producers, nonferrous metal,
electromechanical device,electrical appliances,coal mine, light manufacturing, foodstuff,
furniture, current consumption.

HDP SERIES:
High Durable Polyester (HDP) Series use AkzoNobel proprietary polyester coatings, with the advantage of hig weathering resistance under normal weather conditions. Using hig molecular weight resin, polymer less branched chain, stable molecular bond energy, and not easily photolysis, therefore it['s not easy pulverize and can stay high gloss; Using inorganic ceramic pigment, it's not easy to fade in the sun. Under the condition of normal climate, its excellent weather durability make it suitable for all kinds of outdoor construction and utilization. Its service life can be up to 10 years.
