Some custom said this wire rope mesh will be used indoor.mesh made by 304 stainelss steel will be enough. Then they can save the mesh cost. 

Our suggestion is still using 316 grade stainless steel. if we conside the material cost,ss304 is cheaper than SS 316. But we need to check each square meter of stainless steel rope mesh's weight. some times each square meter of mesh's weight less than 1 kg. In fact you can't save much time.and other mesh process cost is same.
