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 is this roof tile made of?

Stone-coated metal roof tiles are made of galvanized steel sheets coated with stone grains.

First, the stone in JHL ROOF Stone Coated Metal Roofing Tile is known as roofing granules. The granules are made from natural stone mined in quarries, then crushed and screened into various sizes. The granules are manufactured so that when applied and embedded with our acrylic primers, the granules bond together to provide maximum coverage to the roof panel surface.

The particles acquire their vibrant colors through the process of applying a paint-like combination of pigments to the stone particles. The pigment paste 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 that these colored stones and colors will start to fade after a few years? The answer is no. Usually, the stone-coated metal roof tiles produced by regular manufacturers will not lose the color of the colored stone particles on the surface for life. In addition, these colored stone particles not only make the tile more decorative and aesthetically pleasing, but also protect the underlying "substrate" and reduce rain noise.

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

And there will be a layer of anti-fingerprint coating on the galvalume layer, which makes the steel plate have strong hardness and corrosion resistance. This steel plate material also ensures that the service life of the roof tile can reach 30 to 50 years.

From a construction point of view, this galvalume sheet material not only has a long service life and high thickness, but also saves trouble and labor in the actual installation of the construction personnel. Previous roof tiles required a lot of manpower and material loss costs due to their large size and fragility. Painted stone metal roof tiles can save money.

In terms of resource utilization, the metal material of the stone-coated metal roof tiles is destined to be recycled again. That is to say, 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 roofs of every household in the next five to ten years.
