When purchasing stone-coated metal roofing tiles, selecting the right color is crucial for both aesthetic appeal and functional benefits. Here are the available color options:
When selecting a color, consider:
Architectural Style - Traditional homes look great with terracotta or brick tones, while modern homes often suit black, gray, or blue.
Climate Considerations - Lighter shades reflect heat, while darker shades absorb it, affecting energy efficiency.
Surrounding Environment - Choose a shade that complements the natural surroundings and landscape.

Proper packaging and delivery of stone-coated metal roof tiles are crucial to ensure they arrive at their destination in perfect condition, preventing damage during transportation and handling. Here's a detailed guide:
Use a forklift or crane to unload pallets safely.
Avoid dropping or dragging tiles to prevent damage.
Store in a dry, shaded area before installation to maintain quality.
All Forsetra® stone-coated roof tiles are coated with high-quality natural stone chips, ensuring superior durability, weather resistance, and aesthetic appeal. Our stone granules are volcanically formed and sourced exclusively from premium quarries in France and CG Rock, the most renowned Chinese-brand stone granule supplier.
Unlike low-quality alternatives, we never use synthetic or low-grade stone chips from unverified factories. These inferior materials may be cheaper but suffer from poor adhesion, color fading, and reduced weather resistance, compromising roof longevity.

Made from non-combustible Galvalume steel with a stone-coated surface, these tiles provide excellent fire resistance, making them a safe choice for fire-prone areas.
Compared to traditional concrete or clay tiles, stone-coated metal roofing is significantly lighter (around 6-7 kg/m²). This reduces the structural load on buildings, making it easier and more cost-effective to install.
The stone-coated surface effectively absorbs sound, reducing rainfall noise and other external sounds, making the interior quieter.
Ideal for roofs with a slope of 15 degrees or more, ensuring efficient water drainage and preventing leaks.
The lightweight design and stackable structure make shipping and handling more efficient, reducing transportation costs.
Designed to allow proper ventilation, preventing moisture buildup and extending the lifespan of the roof structure.
Resistant to extreme weather conditions, including strong winds, heavy rain, snow, and hail, making it perfect for all climates.
The natural stone-coated texture mimics traditional roofing materials like clay, wood, and asphalt shingles, offering a beautiful and timeless aesthetic.
Built with high-quality Galvalume steel and durable stone granules, this roofing solution offers a long lifespan of 50+ years, ensuring excellent return on investment.
