Galvalume Steel Coil Applications

Galvalume steel coil is a type of steel coil that is coated with a mixture of zinc, aluminum, and silicon, providing excellent corrosion resistance and durability. It has a wide range of applications in various industries, including:

Building Construction: Galvalume steel coil is commonly used in building construction for roofing, siding, and other applications. It offers superior corrosion resistance, high heat reflectivity, and low maintenance, making it an ideal material for commercial and residential buildings.

Automotive Industry: Galvalume steel coil is also used in the automotive industry for manufacturing car parts such as body panels, trunks, hoods, and roofs. The coil's corrosion resistance and lightweight properties make it an excellent choice for automotive manufacturing.

Electrical Industry: Galvalume steel coil is used in the electrical industry for manufacturing electrical appliances and components due to its high resistance to corrosion and heat.

Industrial Applications: Galvalume steel coil is also used in various industrial applications such as storage tanks, pipes, and ducts. Its corrosion-resistant properties make it a popular choice in the chemical, oil, and gas industries.

Agriculture Industry: Galvalume steel coil is used in the agriculture industry for manufacturing greenhouses, livestock sheds, and storage facilities. Its durability and resistance to corrosion make it ideal for harsh agricultural environments.

Overall, galvalume steel coil is a versatile material that offers superior corrosion resistance, durability, and low maintenance, making it an ideal choice for various industries and applications.

Galvalume Steel Coil vs Galvanized Steel Coil

Galvalume steel coil and galvanized steel coil are two types of steel coils that are commonly used in construction, roofing, and other applications. Here are some differences between Galvalume steel coil and galvanized steel coil:

Composition: Galvalume steel coil is made up of a mixture of aluminum, zinc, and silicon, while steel galvanized coil is made up of a layer of zinc on top of a steel base.

Corrosion Resistance: Galvalume steel coil is more corrosion-resistant than galvanized steel coil due to its aluminum content. The aluminum forms a barrier against corrosion that is more effective than the zinc layer on galvanized steel coil.

Durability: Galvalume steel coil is more durable than galvanized steel coil due to its composition. It can withstand harsh weather conditions and extreme temperatures better than galvanized steel coil.

Appearance: Galvalume steel coil has a slightly different appearance than galvanized steel coil due to its aluminum content. It has a slightly duller finish and a more uniform appearance.

Cost: Galvalume steel coil is typically more expensive than galvanized steel coil due to its higher performance and durability.

Overall, Galvalume steel coil is a more advanced and durable material than galvanized steel coil. It offers better corrosion resistance, durability, and appearance, making it a popular choice for roofing, cladding, and other construction applications. However, it is also more expensive than galvanized steel coil. The choice between Galvalume steel coil and galvanized coil ultimately depends on the specific application, budget, and performance requirements.

Galvalume Steel Coil Features

STEEL SEARCHER, a professional galvalume coil supplier in China, provides a wide range of wholesale steel coil galvalume. The aluzinc galvalume steel coil features are as follows:

  • Thermal reflectivity:

    Aluminium-zinc steel plate has a high thermal reflectivity, twice of galvanized steel plate and is often used as an insulating material.

  • Heat resistance:

    Aluminum zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and aluminum plated steel plate high temperature oxidation resistance is very similar, often used in chimney tubes, ovens, illuminators and solar lampshades.                         

  • Corrosion resistance:

    The corrosion resistance of aluzinc galvalume steel coil is mainly due to aluminum, aluminum protection function. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide that prevents corrosion resistance from further corroding the interior.

  • Economy:

    Because the density of 55% Al-Zn is lower than that of Zn, the area of aluminized zinc plate is more than 3% larger than that of galvanized steel plate under the condition of the same weight and the same thickness of gold plating.

  • Easy to paint on

    The plate of aluzinc galvalume steel coil has excellent adhesion to the paint and can be painted without pretreatment and weathering.

  • Aluminium-zinc plated steel plate has an ornate silver-white surface.

  • Aluminized zinc steel plate and galvanized steel plate have similar processing performance and spraying performance.

Aluzinc Galvalume Steel Coil Process

The production process of Aluzinc Galvalume steel coil involves several stages:

Uncoiling: The process starts with uncoiling the hot-dip galvanized steel coil to be used as the base material.

Cleaning: The galvalume steel coil is cleaned to remove any dirt, oil, or grease that may be present on the surface.

Pre-treatment: The cleaned coil is then passed through a pre-treatment process that involves applying a chemical solution to the surface to improve adhesion of the coating.

Coating: The galvalume steel coil is then coated with a mixture of aluminum, zinc, and silicon to form the Aluzinc Galvalume coating. This coating is applied through a continuous hot-dip process or a continuous electro-galvanizing process.

Curing: The coated coil is then cured by heating it in an oven at high temperatures to promote adhesion and to form a durable and uniform coating.

Cooling: Once the curing process is complete, the galvalume steel coil is cooled down to a suitable temperature to prepare it for the next stage.

Cutting: The galvalume steel coil is then cut into various sizes and lengths using shearing machines or slitting lines, depending on the customer's specifications.

Packing: Finally, the cut sheets or galvalume steel coil are packed and shipped to customers for use in various applications.

The Aluzinc Galvalume steel coil process produces a high-quality, corrosion-resistant, and durable material that is ideal for a wide range of applications, including roofing, cladding, automotive, and industrial uses.
