Product Description

Product Description

The hot-dip galvanizing process comes with an array of advantages, notably offering a uniform coating, remarkable adhesion, and an impressively long service life. This sophisticated technique involves intricate physical and chemical reactions between the steel tube matrix and the molten plating solution, resulting in a robustly structured zinc-ferroalloy layer renowned for its corrosion resistance. The alloy layer seamlessly integrates with the pure zinc layer and the steel tube matrix, thereby endowing it with exceptionally strong corrosion resistance.

Galvanized coil springs from a hot plate and undergoes pickling before direct galvanization. This process decidedly reduces steps compared to traditional galvanizing methods, yielding a noticeable price advantage. It possesses a promising development outlook in a multitude of industries including construction, automotive manufacturing, steel warehouse manufacturing, railway passenger car production, and highway guardrail board manufacturing, making it a versatile choice for diverse applications.

Galvanized steel coil stands out as a hot-selling commodity due to its cost-effectiveness, blending durability with a sleek appearance. It offers the ease of painting and use, and is available in an assortment of spangle sizes: big, regular, small, and zero. Moreover, it is lightweight, aesthetically pleasing, and boasts outstanding corrosion resistance. As such, GI coil is celebrated as a pioneering material across numerous sectors including construction, shipbuilding, vehicle manufacturing, furniture, and home appliances.

Specification:

1. Machinability: Ideally suited to meet the processing demands of rolling, coiling, and similar processes.

2. Thermal resistance: Conventional HDG steel plates typically operate effectively under 230ºC and may change color at 250ºC. In contrast, hot-dip Al-Zn coated steel plates can endure environments at 315ºC for extended periods.

3. High reflectivity: Its capacity to reflect heat and light is double that of hot-dip zinc steel sheets, with a reflectivity score exceeding 0.70, comfortably surpassing the 0.65 threshold set by the EPA Energy Star Standard. This makes it an exemplary construction material for energy efficiency.
