What Material is Stone Coated Metal Roof Tile Made of?

Stone-coated metal roof tiles are a new type of roof tiles that are currently popular. What material are these roof tiles made of?

Stone-coated metal roof tiles are made from galvanized steel sheets that are coated with stone particles.
First, the stone in the clad metal roofing tiles is called roofing granules. The pellets are made from natural stone mined in quarries, then crushed and screened into various sizes. The particles are manufactured in such a way that when applied and embedded in our acrylic primer, the particles bond together to provide maximum coverage of the roof panel surface.

Through a process of coating the stone particles with a paint-like combination of pigments, the particles acquire their vibrant colors. The pigment slurry mixture, once applied to the stone, is baked at high temperatures so that the pigment mixture coats the stone in the ceramic process.

Of course, many people worry about whether these colorful stones and colors will start to fade after a few years? The answer is no. Generally, the color of the colored stone particles on the surface of stone-coated metal roof tiles produced by regular manufacturers will not be lost for life. In addition, these colored stone particles not only make the tiles more decorative and beautiful, but also protect the underlying "substrate" and reduce rain noise.

Next, let's talk about the base material of roof tiles. One characteristic of stone-coated metal roof tiles is that the weight is generally only 1/6 of traditional tiles. Why can it be done so easily? The answer lies in the substrate. This base material looks "thin" and looks like a plastic sheet, but its true identity is "galgalsteel sheet", which is made of two main metal materials, aluminum and zinc, plus other auxiliary materials.

And there will be an anti-fingerprint coating on the steel layer to make the steel plate have strong hardness and corrosion resistance. This steel plate material also ensures that the service life of the roof tiles can reach 30 to 50 years.

From a construction point of view, this steel plate material not only has a long life and high hardness, but also saves construction workers trouble and labor in the actual installation. Previous roof tiles required high labor and material loss costs due to their bulk and fragility. Stone-coated metal roofing tiles can save you money on this expense.

In terms of resource utilization, the metal materials of stone-coated metal roof tiles are destined to be recycled again. In other words, if we want to renovate the house in the future, the original stone-coated metal roof tiles of the house can be reused, avoiding material waste and ecological pollution.

Generally speaking, stone-coated metal roof tiles are very competitive in the current roofing building materials market, and they are likely to gradually occupy the roof of every household in the next five to ten years.
