Silver Prepainted Galvalume Steel Coil / Sheets Corrosion Resistance

Coloured Prepainted Galvalume Steel Coil And Sheets Full hard JIS G 3318

1. Description

The production of Prepainted Galvalume Steel Coil is almost the same with Prepainted Galvanized Steel Coil which difference is only the base metal. The base metal for PPGL is GL. Galvalume is the result of an ideal alloy of aluminum and zinc. It consists of aluminum(55%), zinc(43.4%), and silicone(1.6%).
Characteristics of Galvalume:
1) Corrosion resistence:
At verious enviromental conditions, GL shows better corrosion resistence than GI if the thickness is same, its service life is 2 to 6 times than ordinary galvanized steel. The corrosion resistence in the machining parts is much better than that of hot-dip galvanized due to micro cracks demormation parts of aluminum zinc plate is smaller than hot-dip galvanized.
2) Heat resistence:
GL plate can be used for a long time even if under 315℃.
3) Heat reflective
The reflection coefficient is double than that of hot-dip galvanized steel, which can reduce the inner tempeture in summer.

2. Performance Of Antistatic PPGI/PPGL

1) Its machining property and durability match that of the PPGI with common polyester as its base metal.
2) Its resistance to chemicals and solvents is slightly higher than that of PPGI with common polyester
3) Its surface resistance (Ω/cm2) is 10⁶-10⁹Ω (PPGI with common polyester: 10¹³Ω )

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.
