A 45 GSM (grams per square meter) fiberglass mesh product typically consists of lightweight fiberglass strands woven together to form a mesh fabric. The term "GSM" refers to the weight of the fabric per square meter, indicating its density or thickness.
Fiberglass mesh is commonly used in various applications such as construction, insulation, filtration, and reinforcement. In the case of a 45 GSM fiberglass mesh product, the content primarily comprises fiberglass strands. These strands are usually made from molten glass that is drawn into thin fibers and then woven together to create the mesh.
The lightweight nature of 45 GSM fiberglass mesh makes it suitable for applications where a thinner and more flexible material is required, while still providing strength and stability. However, it's important to note that the specific content of the product may vary depending on the manufacturer and intended use. Additionally, certain additives or coatings may be included to enhance properties such as fire resistance, alkali resistance, or adhesion to other materials, depending on the requirements of the application.
