How to distinguish the security screen mesh

More and more people are choosing the security screen mesh. Because the security screen mesh is both beautiful and breathable, it can also achieve anti-theft. However, some merchants will shoddy the 201 as 304 to sell for security screen mesh. At this time, customers need to be vigilant. How to identify whether it is a 304 security screen mesh? Today I am here to briefly introduce the identification method. If you have any other questions, you can leave a message and we will reply to you at the first time.

The main parameters of the security screen mesh are material, wire diameter and mesh number. Below we mainly address these aspects.

There are two ways to distinguish between 201 and 304. Firstly, buyers buy the 304 test syrup in locally. Scraped off the plastic layer on the security screen mesh, and dripped the drug onto the stainless steel wire. The material is slightly discolored or discolored, which is 304. The material becomes red rust, which means the material is 201; Secondly is to cut the small sample with an angle grinder, the spark is less than 304 and the spark is 201; Thirdly, the most authoritative test can bring the sample to the local Conduct quality inspection. The department detects the component content, the genuine 304 material C ≤ 0.08, and the Ni content is 0.08-0.1.

A security screen mesh of the same material, a small difference in wire diameter can cause a square difference of at least CNY2, almost equal to or even exceed the current profit. For example, the security screen mesh has an inner diameter of 0.53 and a unit weight of 1.85-1.9 kg/m2, and a security screen mesh weight of 0.55 is 1.98-2.08 kg/m2. If you are buying a web, you can calculate the volume of the web directly. The film web can be said to take a few average comparisons, and the other line diameters are no longer fine. The general definition refers to the number of holes within 1 inch on the screen. It is basically 13 orders below 06, 07-08 is 11.5 mesh, and 08 is 10.5 mesh. It can be measured directly with a ruler.
