900mm - 1250mm Width Colorcoated Galvanized Steel Sheets And Coils

1. Introduction of Base Metals of PPGI

The base metals for prepainted steel sheet consist of cold-rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel sheet.

Cold-rolled base metal

The prepainted steel sheet processed with cold-rolled base metal features in its smooth and beautiful apperance and the machinability of cold rolled steel sheet, however, in case of any tiny scratch on the top coating may expose the cold rolled base metal in the air and the exposed base metal may rust soon. So the products of this kind can only be used as temprorary isolation measures and indoor materials with low requirements.

Hot-dip zinc coated base metal

The prepainted steel sheet with hot-dip zinc-coated base metal as its base metal not only has the protective function of zinc coating but also has an isolation and pretection function with its organic layer that prevents it from rusting and prolongs its service span longer, than that of hop-dip zinc steel sheet.

Hot-dip alu-zinc base metal

The hot-dip alu-zinc base metal adopts the hot-dip zinc-aluminum coated steel sheet(55% Al-Zn) as its prepainted base metal.

The corrosive resistance of the hot-dip alu-zinc coated steel sheet is twice to five times as much as that of the hot-dip zinc-coated base metal.

Neither serious oxygenation nor oxide scale might appear while continuously or intermittently working with an ambient temperature up to 490℃.

Electro-galvanized base metal

The prepainted electro-galvanized steel sheet adopts an electro-galvanized base metal coated and baked with an organic coating. Owing to the thin zinc-coated layer of the electro-galvanized base metal, the zinc content of the prepainted steel sheet of electro-galvanized base metal is usually 20/20g/㎡, and the products of this kind are not suitable for building walls or roofs outdoors. However, it has esthetic apperance and excellent machinability, which makes it suitable for electrical household appliances, acoustic devices, steel household appliances, interior decoration, etc.

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.
