Galvanized sheet metal

Galvanized Sheet metal coil about to be processed to length

Our cold rolled galvanized steel meets ASTM A-653 with coating options ranging from G30 to G90 is ideal for various industries. It has a smooth, uniform surface and is corrosion-resistant and durable due to the zinc coating. It is perfect for high-stress applications, such as roofing, siding, and structural components, as well as decorative and architectural uses. Our steel meets strict industry standards and undergoes a rigorous quality control process, ensuring consistent and reliable performance in every application.

How does the Zinc coating function?

The zinc coating on galvanized sheet metal serves as a sacrificial layer, meaning that if the sheet metal gets scratched or damaged, the zinc will corrode first, protecting the underlying steel from rust. This property makes galvanized sheet metal suitable for outdoor applications or environments where the metal is exposed to moisture, humidity, and other corrosive elements

 

 

Cold Rolled Steel Sheet Metal & slit coil Offerings

Cold rolled steel is a type of steel that has been processed by passing it through rollers at a temperature below its recrystallization temperature. This process work hardens the steel, making it stronger and more ductile. Cold rolled steel also has a smoother surface finish than hot rolled steel.

What is Galvannealed Steel?

Galvannealed steel is a type of steel that has been coated with a layer of zinc and iron alloy. The process of galvannealed steel begins with hot dip galvanization, where the steel is dipped in a bath of molten zinc. After the zinc has been applied, the steel is then annealed, which is a heat treatment process that causes the zinc and iron to form a bond. This bond makes the zinc coating more durable and resistant to corrosion.

Galvannealed steel has a number of advantages over other types of steel, including:

  • Corrosion resistance: Galvannealed steel is very resistant to corrosion, making it ideal for use in outdoor applications.
  • Durability: The zinc-iron alloy coating is very durable and can withstand a lot of wear and tear.
  • Paintability: Galvannealed steel is easily paintable, making it a versatile material for a variety of applications.

What’s the difference between Galvannealed Steel and Galvanized Steel?

Galvanized steel has a pure zinc coating, provides corrosion resistance, and has a spangled appearance, while Galvannealed steel has a zinc-iron alloy coating, offers enhanced paint adhesion, and has a matte gray appearance. The choice between the two depends on the specific requirements of the application and the desired properties of the steel.

 

What is Bonderized Steel?

Bonderized steel, also known as paintgrip steel or phosphatized steel, is a type of steel that has undergone a surface treatment process to enhance its paint adhesion and corrosion resistance. The bonderizing process involves applying a phosphate coating to the steel surface.

The process starts by cleaning the steel to remove any contaminants and then immersing it in a solution containing phosphoric acid or another phosphate compound. The acid reacts with the steel surface, forming a layer of zinc or iron phosphate. This phosphate coating provides several benefits.

Bonderized steel typically has a dull gray appearance due to the phosphate coating. This finish is suitable for applications where aesthetics are not a primary concern, such as roofing, siding, agricultural equipment, and industrial machinery.

It’s worth noting that bonderized steel is not intended to provide long-term corrosion resistance in harsh environments. If higher levels of corrosion resistance are required, other coating options like galvanized or galvannealed steel may be more suitable.

Electro Galvanized Steel and Zinc Coated Steel

Electro galvanized steel is a type of steel that has been coated with a layer of zinc by means of electroplating. This process involves passing an electric current through a solution of zinc and water, which causes the zinc to adhere to the steel surface. The resulting coating is very thin, typically only a few micrometers thick, but it is highly effective at protecting the steel from corrosion.

Electro galvanized steel has a number of advantages over other types of galvanized steel, including:

  • Uniform thickness: The coating is applied evenly over the entire surface of the steel, which ensures that the corrosion protection is consistent.
  • Smooth surface: The electroplating process leaves a smooth, matte finish on the steel, which makes it suitable for applications where a high-quality surface is required.
  • Good formability: The coating does not significantly weaken the steel, so it can be easily formed into a variety of shapes.

Galvalume steel is a type of coated steel that is composed of a combination of zinc and aluminum, along with trace amounts of silicon. This coating provides enhanced corrosion resistance and durability to the steel. The composition of Galvalume steel typically consists of the following elements:

  1. Steel Substrate: The base material of Galvalume steel is carbon steel, which provides the structural strength and formability.
  2. Zinc (Zn): Zinc is the primary component of the Galvalume coating. It serves as a sacrificial anode, providing cathodic protection to the steel substrate. In other words, the zinc corrodes in preference to the underlying steel, extending the lifespan of the steel.
  3. Aluminum (Al): Aluminum is alloyed with zinc to form a layer of aluminum-zinc alloy on the surface of the steel. This layer contributes to the corrosion resistance of the coating and also helps improve the adhesion of paint or other finishes.
  4. Silicon (Si): Silicon is a minor component in Galvalume steel, and it is added to the coating to enhance the performance of the alloy layer, particularly in terms of its ability to adhere to the steel substrate.

The specific composition of Galvalume steel can vary slightly and is based on the intended application. The combination of zinc and aluminum in Galvalume steel results in a product that offers the corrosion protection of zinc along with the additional barrier and heat-reflective properties of aluminum. This makes Galvalume steel particularly well-suited for outdoor and harsh environments, such as roofing, siding, and other construction applications where corrosion resistance is essential.

Hot Rolled vs Cold Rolled Steel?

Hot rolled steel is produced by rolling steel at high temperatures, which can result in a rougher surface and less precise dimensions, but it is generally more ductile and easier to work with. Cold rolled steel is produced at room temperature, which results in a smoother surface and more precise dimensions, but it may be more brittle and harder to work with. Additionally, cold rolled steel tends to have a higher strength-to-weight ratio and better surface finish than hot rolled steel.
