Product Description

Product Description

The art of hot-dip galvanizing is renowned for its uniform coating, robust adhesion, and extended service life. Witness the marvel as complex physical and chemical reactions unfold between the steel tube matrix and the molten plating solution, resulting in the formation of a tightly structured zinc-ferroalloy layer that exudes exceptional corrosion resistance. This alloy layer elegantly integrates with the pure zinc layer and steel tube matrix, providing formidable protection against corrosion.

Galvanized coil construction begins with a hot plate that undergoes pickling before being directly galvanized. This innovative approach significantly reduces the steps involved when compared to traditional methods, offering a clear price advantage. This process boasts a promising development potential in various sectors, including construction, automobile manufacturing, steel warehouse development, railway passenger car production, highway guardrail board manufacturing, and more.

Galvanized steel coil is one of our most sought-after products, celebrated for its affordability and exceptional attributes. It melds durability with a sleek appearance and is remarkably easy to paint and use. Available in big, regular, small, and zero spangles, this coil offers lightweight construction, aesthetic appeal, and superb corrosion resistance. Consequently, GI coil is embraced across multiple arenas, from construction and shipbuilding to vehicle manufacturing, furniture, and home appliances.

Specification:

1. Machinability: This product meets the processing demands of rolling, coiling, and similar techniques seamlessly.

2. Thermal resistance: Standard HDG steel plate performs optimally up to 230ºC and undergoes color changes at 250ºC. In contrast, our hot-dip Al-Zn coated steel plate endures environments of up to 315ºC for extended periods.

3. High reflectivity: With heat and light reflection capabilities twice that of typical hot-dip zinc steel sheets and a reflectivity exceeding 0.70, surpassing the 0.65 requirement by the EPA Energy Star Standard, it stands out as an ideal energy-saving construction material.
