Q2: What is the standard product thickness and why does it matter?

Standard thickness is 0.40–0.53 mm (±0.01 mm). This ensures structural integrity while minimizing roof load, providing a secure installation even on lightweight or retrofitted trusses.

Q3: How is color longevity achieved and tested?

Color is locked by natural basalt granules bonded via acrylic resin, tested for color fastness under ISO 105-A02 (ΔE<1.5 for 10yrs exposure).

Q4: What installation standards are followed?

Installation follows ANSI/SPRI/FM 4435/ES-1, with recommended overlaps and fastener spacings to ASTM D3161/D7158 for wind and uplift resistance.

Q5: What fire rating does this tile achieve?

All Stone Coated Metal Roof Tile-Grouper Tile products are tested and certified to Class A (UL790/ASTM E108) for fire resistance, meaning they withstand severe external fire exposure.
