PPGI (Pre-Painted Galvanized Iron) roof panels are a type of building roofing material made from
Galvanized Steel Sheets, which undergo surface pre-treatment and are coated with high-performance coatings. This innovative product combines the strength of metal materials with the decorative and weather-resistant properties of the coating, making it an ideal choice for modern building roofing systems.
Core Advantages
Outstanding Corrosion Resistance
Using hot-dipped galvanized base plates, the zinc layer thickness can reach 120-275g/m², providing excellent rust protection.
The surface coating further isolates the base material from external environments, offering dual protective mechanisms.
Laboratory accelerated aging tests show a service life of up to 20-30 years.
Excellent Weather Resistance
Utilizing high-weather-resistant coatings such as PVDF or PE, it has outstanding UV resistance.
It can withstand extreme temperature changes (-40°C to 120°C).
Color stability is good, and it does not fade easily over long-term use.
Lightweight and High Strength
Weighing only 1/5 to 1/10 of traditional tiles, it reduces building load.
Tensile strength exceeds 550MPa, with excellent wind pressure resistance.
Can withstand strong winds (up to typhoon level 17) and moderate snow loads.
Easy Installation
Standardized size design increases construction efficiency.
Can use hidden or exposed fixing systems.
Can be processed into various shapes to adapt to complex roof structures.
Environmental and Energy Efficient
100% recyclable, meeting green building standards.
High reflectivity surface reduces building heat absorption, saving air conditioning energy consumption.
Low VOC emissions during production, environmentally friendly.
