Methods of judging the advantages and disadvantages of metal carved panels
1. When buying a metal carved plate, you can tap the stone with your hand to check its firmness, tap the surface of the metal carved plate, and listen to its sound. To touch, if the stone texture is hard, it will make a clear and firm sound, so avoid picking stones with slight cracks inside.
2. If there are cracks on the surface of the structure, it is easy to crack in the future, and it is not very beautiful for the stone surface with large texture.
3. Observe the surface structure of the stone with the naked eye. The finer the particles, the better the quality.
It is very important to choose a high-quality metal engraving plate. In addition, the so-called A-grade metal carved board is a non-combustible material, while the inorganic material (cement) is A-grade. The inorganic fireproof insulation board is used instead of red brick as the wall insulation material, which reduces the thickness of the wall, saves energy, and indirectly expands the building area. Reduce building weight and act as both thermal and thermal insulation.
