With the burgeoning and popularization of the market, the market price is very chaotic. Some offer very low prices, and they are far too low to be cost-effective. Many manufacturers use cheap wire gauze, manganese steel gauze, and carbon steel. Yarn nets, 201 gauze nets, 202 gauze nets and other inexpensive gauze nets 304 stainless steel gauze nets. There is a lack of wire diameter, thin mesh, poor material, etc., which are tricky to deceive consumers.

First, the magnet to identify true and false 304 Security screen mesh window

The simplest method is to use magnets to absorb diamond mesh screens. Diamond 304 does not absorb magnets. Note that diamond frames that do not attract magnets are 304 Security screen mesh, and the cheaper 201 and 202 diamond magnets do not absorb.
