Pre-Painted Alu-Zinc Steel Coils | Viet Nam Steel

Pre-Painted Alu-Zinc Steel Coils from Viet Nam Steel offer a superior combination of durability, aesthetic appeal, and corrosion resistance. The Alu-Zinc coating (an alloy of aluminum and zinc) provides significantly better protection against rust and weathering compared to standard galvanized steel, making it the preferred choice for long-lasting exterior applications.

Manufacturing Process

These coils are produced on advanced color coating lines. The process begins with rigorous cleaning and pickling of input sheets to remove impurities. A specialized additive is applied to enhance adhesion, followed by a primer coat. Finally, the sheets are painted with high-quality polyester or PVDF coatings and cured in ovens to ensure a uniform, durable finish.

Key Benefits

• Enhanced corrosion resistance due to the Alu-Zinc alloy composition.
• Superior formability and deep-drawing capabilities.
• Wide range of colors and finishes available for architectural flexibility.
• Long service life with minimal maintenance requirements.
• Energy-efficient reflective properties in certain metallic finishes.

Applications

Ideal for industrial roofing, wall cladding, facades, and agricultural buildings exposed to salt spray, humidity, or industrial pollution.
