Placas de acero PPGI vs PPGL: Principales diferencias, aplicaciones y guía de compra

When sourcing prepainted steel products, one of the most common questions buyers ask is: PPGI vs PPGL – which is better? Ambos ppgi and ppgl steel sheets belong to the prepainted steel family and are widely used in roofing, wall panels, and appliances. However, they differ significantly in coating composition, corrosion resistance, and application suitability.

Understanding the ppgi and ppgl difference helps buyers reduce costs, improve durability, and choose the right material for specific projects.

¿Qué es el PPGI?

PPGI steel sheet is produced by applying a color coating on hot-dip galvanized steel. The zinc coating provides corrosion resistance, while the paint layer enhances surface finish and durability.

Características principales de PPGI:

• Buena resistencia a la corrosión en entornos moderados
• Excelente adherencia de la pintura para diversos acabados
• Rendimiento de conformado flexible para la fabricación
• Amplia gama de colores, niveles de brillo y diseños

Aplicaciones comunes:

• Cubiertas de chapa galvanizada
• Revestimientos murales y paneles decorativos
• Paneles traseros del aparato
• Printed pattern sheets for construction projects

In decorative building projects, many buyers prefer ppgi sheets for their wide range of patterns and finishes.

¿Qué es PPGL?

PPGL steel sheet is made from aluminum-zinc alloy coated steel (55% Al, 43.5% Zn, 1.5% Si) with a color coating on top. This combination provides superior durability, especially in aggressive environments.

Características principales de PPGL:

• Excelente resistencia a la corrosión y al calor
• Brillo metálico inconfundible
• Buena durabilidad a largo plazo en climas duros
• Adecuado para aplicaciones de alta temperatura y costeras

Aplicaciones comunes:

• Proyectos de exterior a largo plazo
• Cubiertas y revestimientos industriales
• Edificios costeros
• Estructuras de montaje solar

For industrial and coastal use, ppgl sheets are often chosen over PPGI due to their enhanced lifespan.
