Gypsum board, as a common building material, its hardness level is one of the important indicators to measure its quality. The hardness level not only affects the service life of gypsum board, but also relates to its load-bearing capacity and impact resistance. The following is a method for distinguishing the hardness levels of gypsum boards:

Grade classification: The hardness level of gypsum board is usually divided into three levels: excellent product (A), first-class product (B), and qualified product (C). Excellent products have the highest hardness and the best quality; Qualified products have the lowest hardness and relatively poor quality.

Testing method: The differentiation of hardness levels of gypsum boards is mainly achieved by testing their flexural strength and compressive strength. The flexural strength reflects the resistance of gypsum board to bending force; The compressive strength reflects the bearing capacity of gypsum board under pressure.

Application scenarios: Gypsum boards with different hardness levels are suitable for different application scenarios. High quality gypsum board is suitable for places with high requirements for load-bearing and impact resistance, such as high-rise buildings, large shopping malls, etc; First grade gypsum board is suitable for general construction sites; Qualified gypsum boards are suitable for low-end markets with lower quality requirements.

Purchasing suggestion: When choosing gypsum boards, consumers should choose gypsum boards with appropriate hardness levels based on their actual needs and budget. Generally speaking, first-class gypsum board can be chosen for home decoration and general construction projects; For places with high requirements for load-bearing and impact resistance, it is recommended to choose high-quality gypsum boards.
