Stone Selection Policy

Currently, the major use of stone as decoration purposes, compared with other decoration materials, the biggest difference is that the Department of Natural stone minerals, in many ways, such as various aspects of color, texture, and construction materials, etc. have made it unique Therefore, also in the selection of its application Road; conditions. Overall, the choice of stone to be considered from the following aspects:

  First, the budget cost considerations

Stone is a natural mineral-based, different stone because of its quality, quantity, mining land .... so different, often there will be a significant difference in price, and therefore, when the owners and designers at the beginning of the selection, they should have cost a considerable degree of control.

  Two expression, aesthetics

Other stone color, pattern and texture factor in the selection belongs to the more subjective level, often due to the owners and designers preferences vary, but if natural stone more in-depth understanding of the expression of artistic conception will be designed in even more remarkable flexible.

Classification ore formed mainly igneous, sedimentary and metamorphic rocks are three commonly used local construction marble stone main places category (metamorphic rocks) and granite class (igneous) based; in general, marble stone with more class rich in color and pattern, texture performance on a smooth and gentle-based, and granite class although less variation in color and pattern, but there are more flexible in terms of the texture of performance (see Table 2-1). In addition, the granite appears to be more solemn and classical in the overall feeling.

      Third, the stone quality control

      1. Material uniformity and integrity:
We should try to avoid cracking and other dark, black scar and color problem.

      2. Stone Ingredients:
(1) Avoid excessive inner stone contains iron sulfide, iron oxide, salt, carbonaceous clay .... and other harmful substances.
(2) Avoid stone containing radiation ingredients.
(3) Avoid stone containing mineral components within the high coefficient of thermal expansion, thermal and electrical conductivity, in order to avoid the risk of cracking, thermal and conductive.
