DX51D Cold Rolled Color Coated Galvanized Steel Coil

Premium Pre-Painted Steel with Galvalume, Galvanized, Aluzinc, Aluminum & Stainless Steel Options for Industrial and Architectural Excellence

Discover a versatile range of high-performance metal solutions engineered for durability, aesthetics, and long-term value in global markets. This premium pre-painted steel product combines cold-rolled DX51D galvanized substrate with advanced color coating technology—ideal for applications demanding both structural integrity and visual appeal. Whether you're specifying materials for roofing, cladding, or industrial fabrication, our line includes Galvalume Steel, Galvanized Steel, aluzinc steel, aluminum coils, stainless steel, and prepainted steel—all designed to meet international standards for corrosion resistance, thermal efficiency, and environmental resilience.

Key Features: Superior rust protection through zinc-aluminum alloy coatings (55% Al, 43.4% Zn, 1.6% Si), enhanced UV stability via PVDF, polyester, or HDP paint systems, exceptional weldability and formability, lightweight yet robust profiles, and compliance with ISO, ASTM, and EN specifications. These metals offer extended service life—up to six times longer than traditional galvanized alternatives—and maintain their finish under extreme weather conditions, making them ideal for coastal, arid, and urban environments.

Detailed Overview: The core offering is a cold-rolled DX51D base steel coated with either a galvalume layer (55% aluminum, 43.4% zinc, 1.6% silicon) or a galvanized zinc coating (Z60–Z275). Galvalume provides outstanding heat reflectivity (up to 75%) and corrosion resistance—making it perfect for roofing panels, architectural facades, and automotive components. Galvanized steel offers reliable rust protection with excellent bending and welding properties, widely used in HVAC ductwork, appliance manufacturing, and construction frameworks. For specialized needs, we provide aluzinc-coated steel (AZ150–AZ200), which excels in agricultural structures and heavy-duty industrial roofing due to its superior oxidation resistance. Aluminum coils and plates in 1000, 3000, 5000, and 6000 series alloys deliver lightness without sacrificing strength, while stainless steel grades like 304, 316, and 430 ensure hygiene, non-reactivity, and longevity in food processing, marine engineering, and medical device production. Prepainted steel options feature durable surface finishes that resist fading, chalking, and peeling—critical for exterior building envelopes, decorative panels, and consumer appliances worldwide.

Applications Across Industries: From commercial roofing systems and industrial siding to automotive body parts, packaging containers, and cleanroom equipment, these materials are trusted by engineers, architects, and procurement managers globally. Use galvalume steel in hot climates where solar reflectance matters; opt for aluzinc in humid regions requiring enhanced moisture barrier performance; choose stainless steel for sterile environments such as hospitals or food plants; and select prepainted steel for aesthetic-driven projects like shopping centers, schools, and public infrastructure. Each variant supports sustainable design goals through recyclability, low maintenance, and energy-efficient thermal properties.

User Feedback Highlights: Customers across Europe, North America, the Middle East, and Southeast Asia consistently praise the product’s consistent quality, vibrant color retention over decades, ease of installation, and reduced lifecycle costs compared to untreated or less advanced alternatives. Many report significant savings on maintenance and replacement intervals when using this material in harsh environments such as coastal zones or chemical-processing facilities.

Frequently Asked Questions: What makes galvalume better than standard galvanized steel? It offers up to six times greater corrosion resistance and improved thermal performance due to its aluminum content. How do I choose between PVDF and polyester coatings? PVDF provides superior weathering resistance for long-term exposure, while polyester offers cost-effective performance for moderate climates. Are these materials suitable for green building certifications? Yes—many variants qualify for LEED, BREEAM, and other sustainability programs thanks to recyclable content, low embodied energy, and durability. Can they be customized for specific project requirements? Absolutely—we support tailored thicknesses, widths, finishes, and alloy compositions based on client specifications and regional regulations.
