Baowu Coated Products Introduction

1.Prepainted Steel

Color-coated steel sheets, also known as color-coated steel plates, are manufactured by applying one or multiple layers of organic coatings to the surface of metal coil substrates after special surface treatment. These coatings are then cured at high temperatures through specialized processes to create the finished product. Since the product features various attractive colors upon completion, it is termed “color-coated steel sheet.” We commonly abbreviate it as “color steel sheet” or “color-coated sheet.”

2.The hot-dip Al-Zn coated steel

Hot-dip aluminum-zinc steel sheets are pre-coated steel sheets produced by applying a double-sided hot-dip coating of Al-Zn alloy to cold-rolled steel sheets of various strengths and thicknesses. The coating composition consists of approximately 55% Al, 1.6% Si, and 43.4% Zn by mass percentage. It combines aluminum’s physical protection and high durability with zinc’s electrochemical protective properties. Additionally, the surface exhibits a highly decorative bright silver-gray luster with a regular pattern and a raised texture.

3.Hot dip Al-Zn steel sheet

BaoAM is a member of Baosteel’s GalVAluMag™ series of products. As an upgraded version of the original galvanized aluminum-zinc (GL) coating with added magnesium, it offers superior flat surface corrosion resistance and significantly enhanced cut edge corrosion resistance. It is widely applicable in the construction and home appliance industries. BaoAM™ is also a dedicated eco-friendly product from Baosteel. Built on environmentally conscious manufacturing practices and paired with a specialized weather-resistant, eco-friendly coating for outdoor use, it brings greener credentials and extended longevity to outdoor architectural applications.

Due to the migration of magnesium, the coating forms a dense protective film at cut edges over time, enhancing corrosion resistance.

4.Galvanizing

Hot-dip galvanizing

Hot-dip galvanizing refers to the process of coating steel with molten zinc. Commonly known as “white iron sheet” in China, it has been widely used in construction long before its adoption as a substrate for color-coated steel. Its coating surface exhibits a cast finish, featuring uniformly bright zinc flowers (though automotive and appliance applications often prefer a rough, zinc-flower-free surface). Various surface conditions exist.

  The process of applying zinc to steel surfaces via hot-dip coating for corrosion protection is termed galvanizing. Currently, galvanized steel sheets are extensively utilized in construction, piping, home appliances, color-coated panels, automotive manufacturing, and other industries. To meet market demands, new hot-dip galvanizing production lines are continuously being established, alongside the development of new technologies and product varieties.

5.Colored Coated Products for Livestock Industry

  Specialized colored coated products for the livestock industry differ from ordinary building materials. They must withstand humid heat, strong acids and alkalis, manure and excrement decomposition, and disinfectant solutions. These products require exceptional chemical resistance to withstand the unique chemical environment of livestock facilities. While enduring these rigorous challenges, the paint film must maintain its integrity and performance.
