Our large (21g 7/32") mesh weighs .5 lbs/sq.ft (2.44 kg/m2 ). The rings used in this mesh have a wire diameter of .028 inches, an outer diameter of .277 inches and an inner diameter of .221 inches. The large mesh has approximately 3480 rings/sq.ft. The large rings are approximately a third larger than the medium rings. It has the best strength to weight ratio of all of our products, but the large ring size does allow smaller objects to pass through.
This mesh is made of welded 304 stainless steel and is sold by the linear foot.
