DX51D Z140 Galvanized Steel Coil

EN 10346 DX51D+Z140: Enhanced Corrosion Protection for Durable Infrastructure

Our EN 10346 DX51D+Z140 Galvanized Steel Coils are specifically engineered for projects requiring an elevated level of atmospheric protection without sacrificing material workability. Compliant with the rigorous European EN 10346 standard, this grade provides a robust $140g/m^2$ zinc coating mass, bridging the gap between standard commercial grades and heavy-duty industrial cladding. Whether for HVAC ducting, premium roofing, or agricultural structures
Bomis Steel’s Z140 coils ensure superior longevity and structural reliability.

Technical Specification: The DX51D+Z140 Advantage

Understanding the chemical and mechanical balance of this grade is essential for high-quality fabrication. According to the EN 10346 framework:

• DX51D (Forming Grade): This designation ensures the steel possesses the necessary ductility for cold-forming and bending. It is the industry’s most trusted grade for roll-forming into complex profiles, maintaining a consistent yield-to-tensile ratio.

• +Z140 (140g/m² Zinc Mass): The “140” signifies a total zinc coating weight of $140g/m^2$ (both sides). This provides approximately 40% more sacrificial protection than standard Z100 coils, making it highly effective in environments with higher humidity or moderate salinity.

Key Performance Benchmarks

• Superior Adhesion: The hot-dip process creates a metallurgical bond between the zinc and the steel substrate, passing the 0T-1T bend test without any flaking or peeling.

• Consistent Mechanical Integrity: High-quality base metal ensures predictable performance in automated stamping and profiling machines.

• Environmental Resilience: The Z140 coating mass is specifically rated for C2 and C3 corrosivity categories, providing a long-lasting barrier against oxidative stress.
