Product Description

Product Description

The hot dip galvanizing process boasts unparalleled benefits—uniform coating, formidable adhesion, and an impressive lifespan. As complex physical and chemical interactions unfold between the steel tube matrix and the molten plating solution, a robust zinc-ferroalloy layer emerges, offering superior corrosion resistance. This alloy layer is meticulously integrated with both the pure zinc layer and the steel tube matrix, resulting in exceptional durability against corrosion.

Galvanized coil is innovatively crafted from a hot plate, transitioning directly to galvanization after pickling. Compared to traditional galvanized sheets, this streamlined cold rolling process results in a significant price advantage. It showcases tremendous potential for growth in various sectors such as construction, automobile production, steel warehouse fabrication, railway car manufacturing, highway guardrail board production, and numerous other industries.

Galvanized steel coil stands out as a top-selling product, celebrated for its cost-effectiveness, enduring durability, and sleek appearance. Its ease of painting and versatility make it a preferred choice. Available in diverse finishes—big, regular, small, and zero spangles—it offers lightweight elegance and outstanding corrosion resistance. Consequently, GI coil is rapidly becoming the material of choice across many fields, from construction and shipbuilding to vehicle manufacturing, furniture, and home appliances.

Specification:

1. Machinability: Designed to meet the rigorous demands of rolling, coiling, and other similar processes.

2. Thermal resistance: While typical HDG steel plates perform up to 230ºC, changing color at 250ºC, our hot-dip Al-Zn coated steel plate withstands harsh environments up to 315ºC for prolonged durations.

3. High reflectivity: With double the heat and light reflection capabilities compared to hot-dip zinc steel sheets, its reflectivity surpasses 0.70, exceeding the EPA Energy Star Standard of 0.65, making it an ideal choice for energy-efficient construction materials.
