Observing the color: the quality of the wire mesh fence is judged by the color of the fence. Take the barbed wire fence, because of the difference in the amount of zinc on the hot-dip galvanized and electro-galvanized and the process, the price difference is about 500 yuan, which is correct and fast The difference between the two is to close the good quality together and avoid the loss of itself. The hot-dip galvanized barbed wire is shiny and black, and the electro-galvanized barbed wire is bluish and dirty. It is easy to distinguish the two after observing the color.
The plastic-coated fence can also investigate whether its color is beautiful, whether it is shiny, whether the appearance is flat and shiny, etc., generally good plastic-coated appearance is bright and beautiful (except for frosted fence), while the poor one has no gloss and color Sewage.
Touching feeling: touch the surface with your hand to feel whether it is smooth, blocked, and delicate, etc. A good surface treatment should be smooth and delicate, without scars or bumps. In addition, you can also use your nails to press whether the surface is firm (primarily Check the quality of the plastic layer).
Weigh its weight. The quality and price of the product are fundamentally inseparable from the element of weight. After weighing its weight, the quality is measured, so that it can be summarized and inspected by the manufacturer in the mesh, wire diameter, frame, column and other guardrail components. The problem of cutting corners and materials can be eliminated.
Zigzag wrapping: Take off one iron wire of the guardrail and wrap it around a 2-4 times thick iron rod. If the outer coating is cracked or dropped, it is a substandard product. This method is mainly aimed at galvanized wire guardrail.
