What is the designation for severe weather brick grade?

The correct answer is: SW

The designation for severe weather brick grade is SW, which stands for "Severe Weather." This classification is used to indicate that the bricks can withstand harsher environmental conditions and have been tested for durability in such climates. Bricks marked with the SW designation are specifically formulated and manufactured to resist moisture absorption and other damage caused by frost or severe weather conditions, making them a suitable choice for exterior surfaces in regions that experience extreme weather. This ensures longevity and integrity of the brickwork in the face of challenging environmental factors. In contrast, other designations like MW (Moderate Weather) and NW (Not Weather Resistant) indicate bricks that are suited for less severe conditions or have lower resistance to weather-related stress. FBX refers to a type of brick that has specific aesthetic and structural characteristics but is not directly related to severe weather performance.
