In the structural system of 涂石屋面瓦, although the colored sand seems insignificant, it plays a vital role in the overall performance and appearance of the stone coated roofing tiles. Today, let’s have an in-depth understanding of the colored sand on the surface of stone coated roofing tiles.
The material of the colored sand is mostly selected from natural ores such as quartzite and marble. These natural ores are processed through a series of procedures such as careful screening, crushing, and grinding to form the colored sand we see. Its natural properties endow the colored sand with a rich source of colors. Each grain of colored sand is a masterpiece of nature. When combined together, they form the gorgeous and colorful color system of stone coated roofing tiles. From the deep and calm dark gray to the fresh and elegant off-white; from the passionate red to the serene and profound blue, the colored sand has a wide variety of colors and can meet the needs of different architectural styles and customer preferences. Whether it is the elegant and romantic European architecture, the simple and fashionable modern architecture, or the simple and primitive charm of Chinese architecture, the colored sand can enhance the beauty of the building with its just-right color combinations.
In addition to its decorative function, the colored sand also safeguards the durability of the stone coated roofing tiles. It is like a tough armor, covering the surface of the metal tile and effectively blocking the direct radiation of ultraviolet rays on the metal base plate. As we all know, long-term exposure to ultraviolet rays will cause the metal material to age and become brittle, and the colored sand can greatly reduce this damage and extend the service life of the stone coated roofing tiles. At the same time, the colored sand also has a certain anti-wear ability. In harsh natural environments such as wind, rain, and sandstorms, the colored sand can rely on its own hardness and stability to protect the surface of the metal tile from being easily scratched and worn, ensuring that the tile surface always remains flat and smooth and maintaining good waterproof performance.
The adhesion between the colored sand and the metal base plate is also a key factor in measuring the quality of stone coated roofing tiles. High-quality colored sand can be closely connected with the metal base plate, which benefits from advanced production technology. In the manufacturing process of stone coated roofing tiles, through processes such as high-temperature sintering, the colored sand can be firmly attached to the metal base plate to form an organic whole. This strong adhesion makes the colored sand not easy to fall off during long-term use. Even under extreme weather conditions such as heavy rain washing and strong wind ravaging, the colored sand can still cling tightly to the base plate and will not experience large-scale peeling, thus ensuring the durability of the aesthetics and functionality of the stone coated roofing tiles.
In terms of environmental protection, the colored sand also performs outstandingly. Since it mainly comes from natural ores and does not contain harmful chemical substances, it will not cause pollution to the environment during the entire life cycle of production, use, and disposal. Moreover, when the stone coated roofing tiles reach the end of their service life and need to be replaced, the colored sand on their surface can be recycled and reused, for example, as secondary processing materials for building decoration materials or additive components for road paving materials, meeting the requirements of modern society for green and environmentally friendly building materials.
Therefore, the colored sand on the surface of stone coated roofing tiles is by no means just a decorative material. It has irreplaceable functions in aspects such as aesthetics, durability, and environmental protection. In the production process, SKW has always strictly controlled the quality of the colored sand. From the selection of raw materials to every step of the processing technology, we strive for excellence and are committed to providing global customers with high-quality and high-performance stone coated roofing tile products, making each stone coated roofing tile a bright pearl on the building, shining with unique charm and value.
