In recent years, when building roofs, many people will choose Stone coated metal roof tiles , but those who buy them also say that there are many types of colored stone tiles on the market and they don't know how to choose. In fact, the quality of colored stone tiles will be affected by many factors, including the following aspects:
1. Colored sand: protection of the characteristics of volcanic rock. After the incandescent volcanic rock evolves into basalt, rock grains are formed. Nature makes them exceptionally beautiful, hard and unique. They are calcined by special ceramic glaze at high temperature. 240h UV 500w high-pressure lamp irradiated in% saline alkali for 1200h and heated to 800 degrees in a waste furnace for 10 minutes, and then boiled in boiling water for 15h without fading, long-term use does not form moss.
2. Galvanized steel sheet: Substrate (cold-rolled, hot-rolled) composed of substrate, 55% aluminum-zinc-plated aluminum-zinc layer and alloy layer: It has the advantages of high strength, easy processing, and economy, but it is easy to corrode. 55% Al-Zn plate Al-Zn layer: 55% aluminum + 43.5% zinc + 1.5% silicon and other trace elements. Alloy layer: A thin alloy layer is formed by aluminum and iron to inhibit the growth of brittle new ferroalloys and increase workability.
3. Glue: Glue is the manufacturer's unique secret recipe. Our manufacturer specializes in freezing glue in the cold northern areas for the difference between the north and the south and the glue formula. Compared with southern weather, pure silica gel is used.
