Product Description
Shunbei is a committed Chinese Prime Cold Rolled Galvanized Steel Coil Hot Dip DC51+Z Manufacturers for several years. We are dedicated to producing custom sizes for our galvanized steel coil products. Our offerings are widely used in the construction, home appliance, and automotive industries. Inquire today!
Galvanizing layer of DC51+Z galvanized coil is uniform and tight. Cohesion and anticorrosion resistance are much better, thereby preventing the surface of the steel from oxidizing and corroding for a long service life. In addition to this, the pervaded layer is also very decorative so that it can give nice looks to whatever it is used for. The said cold-rolling base has excellent molding properties and soldering properties and can be processed by all kinds of molding technology such as stamping, bending, cutting etc.. This excellent processing property makes DC51+Z galvanized roll the ideal material for making various assemblies and parts.

Surface Structure
The substrate is made of a high-quality cold-rolled steel plate with a flat surface and certain mechanical properties. It provides the strength and rigidity of the DC51+Z galvanized coil and provides a guarantee for the structural support and seismic performance of the product.
The galvanized layer is a layer of zinc formed on the surface of the substrate by the hot-dip galvanizing process. The galvanized coating is mainly composed of pure zinc and has a uniform and dense structure. It can effectively prevent oxidation and corrosion on the surface of the substrate and provide excellent corrosion resistance.
The galvanized layer of DC51+Z galvanized coil has good adhesion and is not easy to peel off. The thickness of the galvanized layer can be adjusted according to customer needs, generally between 20-60μm. Thicker galvanized layers can provide better corrosion resistance and are suitable for more severe environmental conditions.

Surface types
a) No Spangle: This surface type features a smooth, uniform zinc coating without any visible spangle pattern, providing a sleek and consistent appearance.
b) Small Spangle: Small spangle surfaces exhibit a fine, dense pattern of zinc crystals, offering enhanced corrosion resistance and a visually appealing texture.
c) Regular Spangle: With a balanced distribution of medium-sized zinc crystals, regular spangle surfaces combine good corrosion protection with a traditional galvanized look.
d) Big Spangle: Characterized by large, distinct zinc crystals, big spangle surfaces create a bold, textured appearance while maintaining the durability and corrosion resistance of the galvanized coating.

Features
Corrosion Resistance:Galvanized Steel Coil is a low-cost and efficient way of protecting the steel against corrosion, which is used more frequently. As much as one-half of the total world production of zinc is consumed in this process. Zinc itself provides the steel with a very dense layer of protection and forms the basis for cathodic protection. Even if the zinc coating is scraped off, it would still inhibit the corrosion of iron-based materials through cathodic protection.
Good Cold Bending and Welding Performance:Mostly used is low carbon steel, which must exhibit good performance in cold bending to welding and certain performance when stamping.
Reflectivity: high reflectivity, making it a thermal barrier.
The coating is highly durable, the metallurgical structure formed by the zinc coating is such that it can bear any mechanical damage during handling and use.

Product Process
The production process of DC51+Z Galvanized Steel Coil involves several key steps. First, the cold-rolled steel coil undergoes a cleaning process to remove any impurities or contaminants. Next, the coil is immersed in a molten zinc bath, where a layer of zinc adheres to the steel surface through a hot-dip galvanizing process. The coil then passes through a series of cooling and leveling stages to ensure a uniform and consistent zinc coating. Finally, the galvanized steel coil is inspected for quality, coiled, and packaged for delivery to customers across various industries.
