DX51D Ppgi Ppgl Steel Coil

In the field of building enclosures and industrial protection, the weather resistance and decorativeness of color-coated steel coils directly affect the quality of the project. As Asia's leading color-coated steel manufacturer, Yintu Steel Products has focused on research and development for 15 years and launched two series of color-coated steel coils: PPGI (galvanized) and PPGL (aluminum-zinc coated). Through the precise coating control of DX51D/DX52D/DX53D, it provides a full life cycle protection solution for roof panels, rolling shutters and other scenes.

1. Why choose Yintu steel color coated coil?

Our products have three core advantages for corrosive environments and high-frequency use scenarios:

Dual anti-corrosion system

PPGI: 85μm galvanized layer + 5μm epoxy resin primer + 20μm polyester topcoat, salt spray test over 2000 hours

PPGL: 55% aluminum-zinc alloy coating, corrosion resistance is 3 times that of galvanized, suitable for seaside/industrial areas

Precise mechanical properties

DX51D: Yield strength ≥245MPa, suitable for conventional roof panels

DX52D: Yield strength ≥275MPa, suitable for large-span structures

DX53D: Yield strength ≥300MPa, meeting the needs of heavy-duty rolling shutter doors

Intelligent coating process

Japan ABB robot electrostatic coating, film thickness uniformity error <3%

Ultraviolet curing technology, coating adhesion reaches level 0 (ASTM D3359)

II. Four major technological breakthroughs in Yintu steel color-coated coils

Nano-ceramic modification

Adding silicon carbide nanoparticles, the coating hardness is increased to 2H, and the wear resistance is improved 40%

Self-cleaning surface

Fluorocarbon topcoat contains TiO₂ photocatalytic ingredients, which can be self-cleaned by rainwater washing

Temperature compensation system

Using German infrared temperature measurement technology to ensure the consistency of coatings of different specifications of coils

Environmentally friendly production process

Chromium-free passivation technology + water-based paint, passed ISO 14001 and SGS green certification

III. Wide application scenarios

Building roofs: industrial plants, logistics warehouses, gymnasium roofs

Protective facilities: highway sound barriers, airport fences

Commercial facilities: chain store rolling doors, automatic garage doors

Agricultural equipment: livestock farm ventilation panels, granary enclosure structures
