1. GrC is more suitable for ceiling in kitchen and toilet. These two places are easy to damp and steam space, many coatings will appear deformation and peeling. Therefore, it is necessary to select non hygroscopic materials, such as metal or plastic gusset plates. If other materials are not selected, moisture-proof measures should also be taken, such as painting.

2.在GRC吊頂工作中，一般是采用懸掛式吊頂，除了特別留意材質的選擇，還要嚴格規范施工操作，.安裝位置正確且牢固。吊頂、地面、墻面的裝飾材料盡量選擇不燃或者耐燃材料，因為吊頂里面會鋪設各種線路，不燃或耐燃材質可以避免發生火災情況。

2. In the work of GRC ceiling, the suspended ceiling is generally used. In addition to paying special attention to the selection of materials, the construction operation should be strictly standardized. The installation position is correct and firm. The decorative materials of ceiling, floor and wall should be non combustible or fire-resistant materials as far as possible, because various lines will be laid in the ceiling, and non combustible or fire-resistant materials can avoid fire.
               

3.玻璃或燈箱吊頂要使用玻璃。色彩豐富的彩花玻璃、磨砂玻璃越來越多的應用在家庭裝飾中，為避免發生事故，在GRC吊頂和其他易撞擊位置應該使用玻璃。鋼化玻璃和夾膠玻璃即為玻璃。

3. Glass or light box ceiling should use glass. Colorful colored glass and frosted glass are more and more used in home decoration. In order to avoid accidents, glass should be used in GRC ceiling and other vulnerable locations. Toughened glass and laminated glass are glass.

4.暗架吊頂要設檢修孔。很多家庭吊頂不設置檢修孔，因為會影響美觀，但是一旦吊頂內管線出現了問題，修復就成了大問題。所以GRC吊頂還是設置檢修孔為好，如果覺得影響美觀，可以設置在較為隱蔽的部位，再對檢修孔進行裝飾處理。

4. The concealed suspended ceiling shall be provided with manhole. Many families do not set manhole ceiling, because it will affect the appearance, but once the ceiling pipeline problems, repair has become a big problem. Therefore, it is better to set manhole for GRC ceiling. If it affects the appearance, it can be set in a more hidden part, and then the manhole can be decorated.
