Custom PPGI Steel Sheets - Durable Pre-Painted Galvanized Steel for Roofing, Cladding & Appliance

Why Our PPGI Steel Sheets Are a Game-Changer

We’ve been shipping PPGI steel sheets to contractors and manufacturers worldwide for years, and the feedback is clear: these sheets save time, money, and headaches. Why? Because they’re ​ready to use right out of the box. No messy priming, no endless sanding—just cut, weld, and install.

What Makes Them Stand Out?

• ​Weatherproof & Long-Lasting: The factory-applied polyester coating shrugs off rain, snow, and UV rays. We’ve got roofs in coastal areas still looking new after 10+ years.
• ​Lightweight But Tough: Thin yet strong—perfect for projects where every kilogram counts, like rooftop solar panel frames or trailer beds.
• ​Color That Sticks: Got a specific brand color? We’ll match it. Our custom RAL/Pantone options are popular with furniture makers and architects.

Real-Life Uses We’ve Seen:

• A farm in Texas used our black PPGI for a grain silo roof—they said it’s "like a tin hat for crops."
• A European HVAC company loves our dark green sheets for rooftop AC units (zero corrosion after 3 winters).

Got Questions?

We’ll help you pick the right coating thickness, color, and coil size. Need a rush order? Just say the word—we’ve shipped to Dubai, Germany, and Brazil in under 3 weeks.
