High-Strength Structural Steel for Engineered ExcellenceOur S350GD+Z High-Strength Structural PPGI Coils are specifically designed for applications requiring superior load-bearing capacity and structural integrity. Engineered to meet the rigorous EN 10346 standard for galvanized substrates, these coils are the preferred choice for industrial roofing, C/Z purlins, and deep-profile metal decking where mechanical performance is as critical as aesthetic appeal.
The S350GD AdvantageThe “S” in S350GD stands for Structural Steel, distinguishing it from commercial-grade ductile steels. This grade is defined by its guaranteed mechanical values:Minimum Yield Strength: $350 MPa$. This ensures that the panels can withstand higher wind loads and snow loads without permanent deformation.Tensile Strength: $420 MPa$, providing a safety margin for structural stability.Durability: The +Z (Zinc coating) provides essential cathodic protection, available in masses from Z100 to Z275 to suit various atmospheric environments.
Optimized Formability: Despite its high strength, our S350GD maintains excellent coating adhesion, rated for 2T-3T bending without peeling or micro-cracking.
Weight Reduction: The higher yield strength allows for the use of thinner gauges while maintaining the same structural load capacity, leading to significant material cost savings in large projects.
Consistent Flatness: Utilizing precision tension-leveling technology to ensure perfectly flat coils, essential for high-accuracy automated profiling lines.

Superior Durability: Our coatings use high-quality pigments that resist fading and chalking for up to 15-20 years.
Precision Coating: We use advanced double-coat and double-bake (2C2B) processes to ensure uniform thickness and excellent adhesion.
Advanced Testing: Every batch undergoes rigorous testing, including the T-bend test, Pencil hardness test, and Salt spray test.
Customization: From matte finish to wood grain patterns, we provide versatile surface treatments to meet your architectural needs.
1.what is EN 10346 S350GD +Z Colour Coated Galvanized Coil
EN 10346 S350GD+Z is a hot-dip galvanized structural steel coil specified by European standards. It consists of a structural steel substrate with a yield strength of ≥350 MPa, continuously hot-dip galvanized with a pure zinc layer. It is suitable for structural components in construction, photovoltaic systems, and automotive applications, offering both high strength and corrosion resistance.
