When sourcing safety mesh, you must prioritize material composition and tensile strength. For construction or industrial use, look for High-Density Polyethylene (HDPE) with UV stabilizers to ensure longevity under sun exposure. The mesh size (aperture) should be selected based on the application; for example, debris netting requires a finer mesh (e.g., 1mm to 5mm) compared to perimeter safety fencing. Ensure the weight per square meter (GSM) aligns with your durability needs, typically ranging from 60g/m² to 300g/m².
