Product Description

Product Description

Hot dip galvanizing emerges as a transformative solution in metal protection with its incredible benefits of uniform coating, robust adhesion, and extended service life. This process initiates complex physical and chemical interactions between the steel tube matrix and molten plating solution, resulting in a densely structured zinc-ferroalloy layer renowned for its exceptional corrosion resistance. The alloy layer seamlessly integrates with the pure zinc layer and the steel tube matrix, amplifying its strength against corrosion, ensuring enhanced durability and superior protection.

The galvanized coil is crafted from a hot plate and undergoes a direct galvanizing process post-pickling. This innovative approach reduces the steps involved compared to traditional galvanizing methods, presenting a significant price advantage that is hard to overlook. It showcases remarkable potential for expansion across various sectors including construction, automobile manufacturing, steel warehouse assembly, railway passenger car production, and highway guardrail board creation, among others.

Galvanized steel coil has become a sought-after product due to its cost-effectiveness, durability, and polished appearance. It not only boasts versatility with ease of painting and application but also offers different spangle options - big, regular, small, and zero. With its lightweight construction, appealing aesthetics, and superior corrosion resistance, GI coil emerges as a preferred material across diverse industries such as construction, shipbuilding, vehicle manufacturing, furniture, and home appliances.

Specification:

1. Machinability: This material perfectly meets the requirements for various processing methods, including rolling and coiling, ensuring flexible application.

2. Thermal resistance: While standard HDG steel plates operate effectively up to 230ºC, displaying color changes at 250ºC, the hot-dip Al-Zn coated variants endure environments up to 315ºC, delivering sustained thermal resilience.

3. High reflectivity: Exhibiting double the heat and light reflection compared to traditional hot-dip zinc steel sheets, it boasts a reflectivity exceeding 0.70, surpassing the EPA Energy Star Standard requirement of 0.65, rendering it an ideal choice for energy-efficient construction materials.
