In recent years, stone – coated roofing tiles have become increasingly popular for their combination of beauty and practicality. However, a question lingers in many people’s minds: Will stone – coated roofing tiles rust?
Firstly, it should be noted that stone – coated roofing tiles do have the possibility of rusting, and this mainly stems from three reasons.
Firstly, the insufficient thickness of the zinc layer on the base plate. The base plate of stone – coated roofing tiles usually adopts aluminized – zinc steel plates, and the zinc layer plays a crucial role in anti – corrosion. When the zinc layer is not thick enough, in harsh environments such as the seaside, which are humid and full of salt spray, its protective ability will be greatly reduced. The salt in the salt spray is highly corrosive and can accelerate the metal’s oxidation process. If the zinc layer cannot provide sufficient resistance, the steel plate will be easily exposed to the corrosive environment, thus leading to rusting, which will seriously affect the service life and performance of the stone – coated roofing tiles.
Secondly, flaws in the production process. In the production process of stone – coated roofing tiles, the drying treatment of glue is of vital importance. If the glue is not completely dried, the residual moisture will be trapped inside the tiles. As time passes, this moisture will gradually erode the metal base plate and undermine its structural integrity, thereby leading to rusting. This process may be relatively slow, but it continuously has a negative impact on the quality of the stone – coated roofing tiles, causing problems such as surface discoloration, deformation, and even the appearance of rust – like holes on the tiles.
Thirdly, improper transportation and storage. During transportation and storage, if the stacked tiles in pallets are soaked in water or rained on, the water will seep into the gaps between the tiles and is difficult to drain quickly. If the tiles remain in such a humid state for a long time, the metal base plate will inevitably be corroded and rust. In addition, it is also extremely dangerous to place the tiles together with chemical substances. Many chemical substances are highly corrosive or volatile and may react with the metal material of the tiles, destroying the protective layer on their surface and accelerating the rusting process.
Therefore, in order to effectively prevent stone – coated roofing tiles from rusting, relevant requirements must be strictly followed during storage. They should be stored in a well – ventilated and dry indoor environment to ensure that the air can circulate freely and take away the possible moisture. At the same time, stone – coated roofing tiles should be kept away from various chemicals to avoid potential chemical reactions. They must not be exposed to rain or soaked in water. After all, metal materials are inherently at risk of rusting, and any negligence may lay hidden dangers for future use.
It’s worth noting that after the stone – coated roofing tiles are installed on the roof, the situation is different from that of stacked storage. The tiles on the roof are laid in a single – piece manner, and there are good ventilation gaps between them. Even if it rains, the rainwater is difficult to accumulate for a long time and can evaporate and dry quickly under the sun’s irradiation, so the tiles will not be soaked in water for a long time. However, the stacked tiles are prone to form water – logging dead corners, and once the water enters, it’s very difficult to drain, which greatly increases the risk of rusting.
Therefore, although stone – coated roofing tiles have the possibility of rusting, as long as strict control is exerted over the thickness of the zinc layer on the base plate, the production process, and transportation and storage, the risk of rusting can be effectively reduced, the service life can be extended, and durable, beautiful, and reliable roof protection can be provided for buildings.
