Aluzinc PPGL Steel Coil SGLCC SGLCD DX51D 52D 53D GB Standard KS
1. Definition
The basic material for Colorful Steel Coils is hot galvanized steel sheet or high strength aluminum alloy sheet. Using the most state of art technique and equipment to degrease the cold rolled sheet, hot galvanized steel sheet or high strength aluminum alloy sheet on multistage, and rinse, chemical transformation treatment, then continuously clean the steel strip and aluminum strip. Moreover, use the most advanced curing furnace to solidify/baking the coating.

4. Production core strengths
1) 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. | |||
2) 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. | |||
3) 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. | |||
4) Resistance to low temperature: Coating protecting mechanisms: most of the paint can keep stable processing performance above -10 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. |
5. Quality Assurance
HANKE has already passed the authentification by the ISO9001, ISO14001 and KS D 3520 in succession and established a completed set of quality assurance system, and under this system, there has a complete set of regulations for ordering, order handling, quality design, purchasing raw materials, working production schedule, production, test, inspection, packaging, storage, delivering, etc.
Wuhan Hanke Color Metal Sheet Co., Ltd.
Wuhan Hanke Color Metal Sheet CO.,LTD. (hereinafter referred to as HK), established in 2001, was located in the Wujiashan Economic and Technological Development Zone in Wuhan(No. 359 Gexin Road). HK is a national high-tech enterprise which produces color coating steel sheet primarily. The color coating steel sheet line is designed by WISDR (Wuhan Irion & Steel Design Institute), which owns the advanced processing equipment, testing and inspection equipment and PLC automatic control system of Siemens. In 2009, HK has invested in technological upgrading and equipment improving which improves the production capacity and quality greatly.
HK has obtained Certificates of International Quality Management System Certification (ISO9001) in 2005, Korea Industrial Standard Certification (KS D 3520) in 2013 and International Environmental Management System Certification (IS14001) in 2014. At the same time, HK gains honors of “Famous Trademark of Wuhan”, “Famous Trademark of Hubei”, ”Credit Enterprise”, etc. since establishment.
Our main product is color coating metal sheet. It uses the finishing hot galvanized steel as the raw materials, which is produced by Wuhan Iron and Steel (Group) Corporation (hereinafter referred to as WISCO), and we customize the special GI mark DX51D+Z(HK) with them. We have signed strategic cooperation agreement with Double-Tiger Coatings Limited Company which focuses on coating for more than 100 years, and have set up a public laboratory of coating, which lay a solid foundation to improve HK products’ quality.
Our products have a complete range of specifications and colors, we have a series of colors which are familiars with customers abroad to choose, as well as customized according to customer’s requirement. Wuhan and other cities in Hubei are our basic market, and our business is expanding to surrounding provinces. We also export to Southeast and South of Asia, the Middle East, South Korea and Russia, etc. HK has a good prestige and public praise in the domestic and foreign market.
HK is keeping on developing new markets. Meanwhile, we pay much attention to brand building and quality improvement of product. All the time, HK has been sticking to the brand conception of “good base zinc, good surface color, and every lay has its value”, insisting on the enterprise principle of “honesty, consideration, and quality”, and continuing to promote HK products from the country to the world .
In order to meet customer's requirement and expand market, one trading company in China and one in Singapore were established at the right moment, which is much more convenient for customer and us.
