Key Features and Advantages:
Corrosion Resistance: Corrosion resistance is 3–6 times that of pure galvanized steel sheets; it can withstand over 1,000 hours of salt spray testing without red rust.
Heat Resistance: Withstands temperatures above 300°C and exhibits excellent resistance to high-temperature oxidation.
Thermal Reflectivity: Thermal reflectivity is twice that of galvanized steel sheets, making it suitable for use as a thermal insulation material.
Processability: Excellent stamping, bending, and roll forming capabilities.
Weldability: Compatible with various welding methods, including spot welding and arc welding.
Cost-Effectiveness: Reduces the cost per kilowatt-hour over a 25-year lifecycle, offering significant advantages in total cost of ownership.

FAQ
Q: What is DX51D+AZ120?
A: DX51D+AZ120 is a steel sheet with a 55% aluminum-zinc alloy coating, where:
DX51D: Low-carbon steel substrate for cold forming (European standard grade, corresponding to Chinese national standard DC51D)
AZ: Aluminum-zinc alloy coating
120: Total coating weight on both sides: 120 g/m²
Q: Why do cut edges on galvanized-aluminum sheets rust easily? How can this be addressed?
A: Cause: The AZ coating contains up to 55% aluminum and only 43.4% zinc, resulting in weaker anodic protection. The exposed steel substrate at the cut edges is prone to electrochemical corrosion in humid environments.
Solution: Apply anti-rust paint, perform edge folding, use fingerprint-resistant sheets, or upgrade the material.
Q: Are you trading company or manufacturer ?
A: We are manufacturer, and We are the factory for Metal Steel Fabrication, Laser Cutting, Bending, Welding, Material Cutting into Length, Machining, all Types of Structures and parts can be produced based on your drawings.
