What do you know about stone thickness?
1. Introduction to Stone Thickness Evolution In the 1990s, the thickness of stone in the stone processing industry was usually 20mm or greater. However, by the beginning of this century, the thickness of stone began to change, decreasing from 20mm to 18mm, 16mm, and even 10mm. If it is necessary to reduce the weight of buildings, using stone with a thickness of less than 20mm, or even 10mm, as long as the installation strength of the stone meets the usage requirements, it is understandable. Just like ceramic tiles, should their thickness not be more than 10mm? However, for natural stone, due to its natural nature, it is influenced by the natural environment and geological processes during its formation. Different stones have significant differences in their physical and chemical composition and properties. Some stones have a thickness of 20mm or even thinner, and their strength can still meet the requirements of building decoration. However, some stones may not necessarily meet the strength requirements. Therefore, it is necessary to distinguish and differentiate between them. Thin and low strength stones cannot be used for buildings with strength requirements. 2. Differentiation of Stone Types and Thickness Requirements In practice, there are few nations, industry, and local standards that regulate the appropriate thickness of stone used in buildings. Only appropriate specifications and requirements have been made for the thickness of curtain walls. However, are these thickness requirements scientific and reasonable? The requirements for stone thickness in building decoration should be analyzed in detail, treated differently, and not generalized. It depends on factors such as the variety of stone, the environment in which it is used, the function and purpose of the stone, and the installation method of the stone. Some stones are a few millimeters or even 10mm thick, and the problem is not too big. For example, when installing wall stones with a height of less than 3m and using adhesive installation, thin stones or even 10mm thick stones can be used when the specifications are not large. The thickness of the stone used for non load bearing cabinets that only serve decorative purposes can be thinner. However, when we abuse the thickness of stone without distinguishing specific situations, stone varieties, usage environments, and safety requirements, we are wrong! 3. Practical Issues and Standards in Stone Thickness Take some kind of construction projects as an example, such as a project that requires a stone thickness of 25mm or 20mm. Due to the difficulty of supplying 25mm thick stone in some countries' markets, some stone companies have negotiated with the general contractor and agreed that the thickness of the stone can be 23mm or 18mm (verbal agreement), without signing a written stone change agreement or contract. The project took several months from start to finish, during which neither the fi...
