EN 10346 DX51D+Z PPGI Coil

EN 10346 DX51D+Z PPGI: European Precision Forming Standard

EN 10346 DX51D+Z pre-painted galvanized steel coils represent the highest level of European engineering standards for color-coated steel. This product is designed for a wide range of applications, from intricate architectural flashing to robust sandwich panels. The coil combines the high ductility of the DX51D substrate with advanced organic coating technology, ensuring long-term structural and aesthetic integrity.

Understanding the DX51D+Z Substrate
The EN 10346 standard specifies the requirements for continuously hot-dip coated steel sheet products. Our pre-painted galvanized steel coils utilize the DX51D grade, characterized by the following:

“D” (Ductility): Designed for bending and forming. It exhibits excellent mechanical property consistency, preventing micro-cracking of the zinc layer during high-speed roll forming.

“51” (Steel Grade): A reliable commercial-grade steel, offering both strength and cost-effectiveness.

“+Z” (Zinc Coating): We offer a range of zinc coating weights from Z100 to Z275, ensuring the necessary cathodic protection for different corrosion classes (C1 to C5).

Key Performance IndicatorsFlexibility:

Rated for 0T-2T bending, ensuring no paint peeling even on sharp 180-degree folds.Surface Quality: Available in various finishes including Smooth, Matt, or Wrinkled, with strict gloss control ($\pm 5$ units).Zinc Adhesion: The hot-dip process ensures a metallurgically bonded zinc layer that won’t flake during fabrication.

EN 10346 DX51D+Z PPGI Coil Application Scenarios

• Outdoor Mild to Moderate Corrosive Environments
  For example, outdoor building scenarios in urban or rural areas, such as residential roofs and exterior wall cladding, or small outdoor public facilities such as bus stop shelters and community fences. These environments are characterized by natural wind and rain, small amounts of dust, and slight changes in air humidity. The double-layer anti-corrosion structure of this steel provides sufficient protection, while the precoated layer maintains a clean appearance.
  However, it is not suitable for long-term exposure to high-salt spray environments near the coast or heavily polluted industrial areas.General Industrial Environments
  For example, equipment casings, instrument protection cabinets, and small storage racks in light industrial production workshops. These environments may have small amounts of dust and mild chemical volatile substances. The anti-corrosion and wear resistance of this steel can meet the usage requirements of these environments and reduce equipment maintenance costs.Temperate and Subtropical Climates
  This steel is more suitable for use in areas with relatively mild temperatures, small temperature fluctuations, and no extreme high or low temperatures. its anti-corrosion and weather resistance properties can be fully utilized; for extremely cold or long-term high-temperature exposure areas, a coating type with stronger weather resistance should be selected, such as PVDF coated products.
