Selection and identification of invisible protective wire

There are many types of invisible anti-theft wire steel on the market and the quality varies.

There are 202, 304, and 316 in terms of materials. 202 is a commonly used stainless steel variety and is widely used in the production of stainless steel pipes. It is generally recommended to install 304 or better 316 steel wire in cities in China. The rust prevention life of 304 steel wire is long, and it is the main force of invisible protective wire. However, 316 steel wire has better rust resistance in humid environment. And of course the cost is higher!

The composition specifications of the stealth anti-theft wire are: 6 * 7 + 1, 12 + 1, 7 * 7. At present, 12 + 1 is more commonly used, and the appearance is smoother and translucent. 6 * 7 + 1 and 7*7 are also popular with customers because of their softness.

Wire diameters currently on the market are: 1.55mm, 1.85mm. 2.0mm, 2.3mm, 2.5mm, 3.0mm 3.5mm. Theoretically, the thicker the steel wire, the greater the force, but no matter how thick, the steel wire can still be cut, so it is recommended to choose a thinner wire to meet the requirements of protection, and the vision is more beautiful. The thicker wire violates the concept of invisibility and has a greater impact on the landscape.

Therefore, in the selection of the steel wire, combine with your own situation, choose the product you like, and if the conditions allow, it is recommended to install a steel wire with a better material.

Simple identification of wire quality:

Drop the medicine on the steel wire. If the steel wire is red, it can be qualitatively identified as 202 steel wire (the medicine bottle has a color corresponding to the model), and the color of the 304 steel wire has not changed.

Is the wire wrapped in plastic or nylon? I tell you clearly that nylon is much better than plastic in terms of anti-aging, and at the same time, the cost is much higher. Many manufacturers often charge less, but how do you tell? The easiest way is to fold the wire in half. If the rubber becomes white and discolored, it is a plastic film. If it does not change, it is nylon rubber. In short, when choosing an invisible protective net, you must carefully identify it. If it is not steel wire, the color is similar, it is best to use a potion to detect it; if the color of the steel wire is white, it is generally galvanized iron wire. This wire is not only rusty but also has a long elongation. loose.
