SECURITY MESH SCREEN ARE YOU BUYING RIGHT? DON’T BE DECEIVED BY THIS MATERIAL
Security Mesh Screen are you buying right? Don’t be deceived by this material
The Security Mesh Screen is a screen made of stainless steel. After being installed at home, it has the functions of anti-theft, anti-mosquito and anti-mite. It is very safe, firm and has a long service life. Therefore, the comparison of the screens in the Beijing market is currently used. wide. So how do you choose the diamond screen?
First, look at the profile of King Kong Net, the size and wall thickness of the diamond mesh screen profile, the thicker the material, the higher the firmness.
Second, look at the hardware, workmanship and surface treatment of the diamond screen.
Good diamond mesh screen handles work fine, bad work is rough.
The good quality hardware lock has super strong anti-theft function, including four lock points, and the lock point is relatively uniform. The upper and lower hinges are not exposed outside, but are directly hidden inside the hinge, so the four-point anti-theft lock The effect is better.
The bad hardware locks are only fixed by two plugs, which are old-fashioned locks, and the anti-theft effect is very poor.
n fact, there is also a cheaper net in the market, which is made of iron mesh. If this net is installed in your home, it will rust if it takes a long time, and even a large area of rust.
So how do you distinguish between stainless steel mesh and iron mesh? Use a magnet.
If it is a stainless steel gauze, the magnet will not be adsorbed. If it is a wire mesh, the magnet will be adsorbed. This is the principle that uses stainless steel and ordinary iron mesh materials.
The stainless steel mesh actually has good and bad points. The material of a good stainless steel mesh should be 304. The material of a poor stainless steel mesh is 201. So what is the difference between 304 and 201?
201 contains high manganese, the surface is very bright, with dark bright, high manganese content is easy to rust. 304 contains more chromium, the surface is matte and does not rust. The two are put together and there is comparison.
The most important thing is the different corrosion resistance. The corrosion resistance of 201 is very poor, so the price is much cheaper. And because 201 contains low nickel, the price is lower than 304, so the corrosion resistance is not as good as 304.
So how to judge the anti-rust ability of the three networks?
Prepare a bottle of stainless steel identification solution, first scrape off the top layer of the three-layer net, then apply the stainless steel identification solution, and place a piece of paper underneath. After two minutes, see what changes have been made.
Look at the iron mesh first, and look at the iron mesh, there will be a lot of rust spots have penetrated into the paper. 201 stainless steel mesh, it also has rust spots falling onto the white paper, and finally 304 has almost no rust spots.
