What is a Galvalume Coil?

Galvalume Coils are made by coating a steel substrate with a mixture of aluminum, zinc, and silicon. The coating for Galvalume Coils is applied through a continuous hot-dip process, where the steel coil is immersed in a molten bath of the coating material. The coating composition typically consists of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon.

The combination of aluminum and zinc offers excellent corrosion resistance, as both metals have inherent protective properties. The aluminum provides a self-healing mechanism, forming a thin, transparent oxide layer that prevents further corrosion, while the zinc acts as a sacrificial anode, protecting the underlying steel from rust.

Galvalume Coils are widely used in the construction industry for roofing, cladding, and other applications requiring corrosion-resistant and durable materials. They offer a longer lifespan compared to traditional galvanized steel and are known for their superior resistance to atmospheric corrosion, heat, and sunlight exposure.
 

Applications for Galvalume Coils

Galvalume Coil�s unique protective characteristics and economical price point make it ideal for:

• Residential and Commercial Exterior Building Products
• Roofing
• Siding
• Fencing
• Gutters
• Cabinetry

Painted Galvalume Coils

Painted Galvalume coils are Galvalume coils that have been further processed with a pre-applied paint coating. The Galvalume Coil steel substrate provides excellent corrosion resistance, while the pre-painted coating enhances the aesthetic appeal and adds additional protection.

The painting process involves applying a layer of paint to the Galvalume Coils through a continuous coil coating line. The coils are first cleaned and treated to ensure proper adhesion of the paint. Then, a primer is applied to enhance adhesion and provide a smooth base for the topcoat. Finally, a topcoat of paint is applied, which can be in a wide range of colors and finishes.

Painted Galvalume Coils offer several advantages. They combine the corrosion resistance and durability of Galvalume steel with the versatility and aesthetics of the pre-painted finish. The pre-applied paint provides an additional layer of protection against environmental elements, such as UV radiation and moisture, while also allowing for customization in terms of color and design.

These coated steel coils are widely used in various applications, including roofing, wall cladding, garage doors, appliances, and other architectural and industrial applications. They offer a durable, attractive, and low-maintenance solution for projects that require both corrosion resistance and aesthetic appeal.

Painted Galvalume coils vs. Prime Painted Galvalume coils

Painted Galvalume Coils and Prime Painted Galvalume Coils are similar in that they both refer to Galvalume Coils that have undergone a pre-coating process with a paint system. However, there is a distinction between the two terms:

Painted Galvalume Coils

Painted Galvalume Coils refer to Galvalume steel coils that have been pre-coated with a paint system. These coils come in various colors and finishes, offering versatility and customization options for different applications. Prepainted Galvalume steel coils provide aesthetic enhancement and additional protection against environmental elements such as UV radiation and moisture. These coils are widely used in applications where both functionality and visual appeal are important.

Prime Painted Galvalume Coils

Prime Painted Galvalume Coils are a subset of Painted Galvalume Coils that meet higher quality standards. The term �prime� signifies that these coils are of superior quality, free from defects or imperfections, and adhere to strict industry standards. Prime Painted Galvalume Coils undergo stringent quality control measures during the manufacturing process to ensure consistent and reliable performance. These coils are sought after in applications where a high level of durability, corrosion resistance, and visual aesthetics is required.

In summary, while both Painted Galvalume Coils and Prime Painted Galvalume Coils are coated with a paint system, the term �prime� distinguishes the latter as a higher quality subset that meets strict quality standards. Prime Painted Galvalume Coils are known for their superior performance, durability, and aesthetic appeal.  

Goldin Metals' Galvalume Coil's offers rust resistance, fire resistance, and elemental onslaughts resistance. Galvalume Coils are carbon steel coated with an aluminum-zinc alloy using a continuous hot-dipped process combining the corrosion protection and high-temperature resistance of aluminum with the formability and galvanic protection of zinc.
