Galvalume steel coil has become an increasingly popular material in various industrial sectors due to its superior corrosion resistance, heat reflectivity, and cost-effectiveness. Whether you're working in construction, petrochemicals, food processing, or energy, choosing the right Galvalume steel coil is essential to ensuring long-term performance and structural reliability.
As a trusted exporter of premium metal materials, Fuchuan Metal Co., Ltd. specializes in the production and global distribution of stainless steel coils, sheets, pipes, high-temperature alloys, nickel-based alloys, Hastelloy, aluminum, copper, and more. With deep industry experience and a focus on quality, Fuchuan serves a wide range of demanding sectors—from aerospace and nuclear power to shipbuilding and industrial manufacturing.
In this article, we’ll walk you through the most important factors to consider when selecting the right Galvalume steel coil for your specific industrial application.
1. Understand the Application Requirements
Before choosing a Galvalume steel coil, you need to analyze the environment and purpose of the application:
-
Will it be used outdoors or indoors?
-
Is the environment coastal, industrial, or highly corrosive?
-
Is aesthetic appearance important (e.g., visible cladding)?
-
Does the material need to withstand high temperatures or mechanical stress?
For example:
-
Roofing and siding in coastal areas benefit from Galvalume due to its salt-corrosion resistance.
-
Interior wall panels in warehouses prioritize durability and reflectivity.
-
HVAC ductwork or insulated panels need materials with precision thickness and thermal performance.
2. Choose the Right Coating Weight (AZ Coating)
Galvalume is coated with an alloy of 55% aluminum, 43.5% zinc, and 1.5% silicon. The AZ coating level (e.g., AZ50, AZ55, AZ150) indicates the coating mass per square meter, which directly affects corrosion resistance.
-
AZ50–AZ70: Suitable for indoor or mildly corrosive environments
-
AZ100–AZ150: Recommended for outdoor and harsh industrial conditions
-
AZ180+: Ideal for extreme environments (chemical plants, coastal zones, etc.)
Fuchuan Metal provides Galvalume steel coils in various AZ coating grades based on your exact environmental exposure and durability needs.
3. Select the Correct Thickness and Width
Coil thickness and width determine how well the material fits your equipment and structural specifications. Standard Galvalume coils range from 0.25mm to 1.2mm in thickness, and 600mm to 1250mm in width, but custom dimensions are often needed for niche applications.
Common use-cases by thickness:
-
0.3–0.5 mm: Residential roofing, wall cladding, appliances
-
0.6–1.0 mm: Industrial roofing, ducting, sandwich panels
-
1.0 mm+: Heavy-duty applications, structural components
Fuchuan Metal Co., Ltd. offers customized thickness and width options with tight tolerances, perfect for complex industrial fabrication processes.
4. Check Mechanical Properties and Grade
Depending on the forming or structural requirements, you’ll need to consider:
-
Yield Strength (MPa)
-
Tensile Strength
-
Elongation (%)
-
Hardness
Applications involving bending, stamping, or deep drawing may require soft temper (e.g., CQ grade), while structural uses may benefit from high-strength grades (e.g., structural steel with higher yield strength).
Fuchuan’s engineering team can help match your mechanical property needs with the right steel grade—ensuring performance, safety, and compliance.
5. Surface Finish and Aesthetic Options
For projects where appearance matters—such as exterior panels, signage, or architectural design—you may want specific surface finishes such as:
-
Regular spangle or minimized spangle
-
Matte or glossy coating
-
Pre-painted or color-coated Galvalume
Fuchuan also offers pre-coated and patterned Galvalume coils for projects that demand both functionality and visual appeal.
6. Compliance, Certifications, and Testing
Industrial applications often require materials that meet international standards and certifications such as:
-
ASTM A792
-
EN 10346
-
ISO 9001 Quality Management
-
REACH/RoHS compliance (for food-grade or eco-sensitive applications)
Fuchuan ensures every batch of Galvalume coil is rigorously tested for:
-
Coating weight accuracy
-
Surface finish consistency
-
Corrosion resistance
-
Dimensional precision
7. Consider Logistics and Supply Chain Support
