Thanks to the anchoring system on four sides and hidden nails, the aluminum tiles can withstand winds of over 200 km / h while maintaining their waterproofness. With the compact layer of oxide that forms naturally on the surface of aluminum, tiles will not rust, rot, warp or chip.
The only drawback of aluminum compared to steel is its fragility to impact. Very large hailstones can add unwanted relief to the tiles, without affecting their durability.
