The black powder coated, 316 marine grade stainless steel provides greater resistance to pitting corrosion than other grades of steel. The 1.62mm aperture and 42.5% open area means ForceField provides excellent visibility and airflow. While 316 steel is .8mm diameter wire, it is ultra high tensile giving the mesh its strength to ensure it passes the shear and knife shear parts of the Australian Standards security test (AS5039).
