stone coated metal roof tile is based on Al-Zn steel.the before,after protective film treatment ensure to be the best roof .

Color stone coated metal roof tile is based on Al-Zn(known as zincalume or galvalume steel)steel.the before and after protective film treatment,together with high precision pressure-shaped gravel ensure the roof to be the best roofing material.coated with an alloy composed of Al 55%,Zn 43.4%,Si 1.6%,with non-toxic acrylic adhesive and natural stone,color stone coated metal roof provides the advantages of long life,strength,durability and beauty.

Super-weatherability

1)Fires-resistance :

Both Al-Zinc steel and the stone chips are non-organic materials ,they are naturally and proved not combustible

2)Premium performance in earthquake:

Stone-coated metal roof tiles are light and strong,they won’t easily cause damages to the understructures of the buildings in earthquakes.

3)Snow-resistance weight bearing anti-sliding:

Stone-coated metal roof tile is characterised with snow-resistance,weight bearing and anti-sliding,and thus problems in the freezing areas can’t be worried.

4)Wind resistance:

Scientific interlocking system design and proved installation techniques gurantee the roofing system more safety in the storms cloudbursts and hurricanes.

5)Storm resistance:

The roof tile is not noisy,and often much quieter than the asphalt shingle roof or a heavy traditional wood shake roof.there won’t be any leakages in the storms ,and the roof tile is washed and appears as if it was newly reinstalled.

6)Safety in lightning:

There is no increase in the likelihood of being struck by lightning,in case the lightning does strike,the energy safely dissipates and exits into the ground.

7)Hailstone resistance:

The stone-coated metal roof tiles are proved to bear the hailstones without causing damages.
