In life, guardrail nets are widely used because of their low price and convenient transportation, production, and installation. However, precisely because of its huge demand, the quality of the products on the market varies.
There are many quality parameters for guardrail net products, such as wire diameter, mesh size, plastic coating material, wire diameter after plastics, column wall thickness, etc. However, when purchasing, you only need to master the following two parameters: Weight and overmolding.
The weight of guardrail net includes two aspects: weight and net column weight. In purchasing, nets and net posts are calculated separately, so it is necessary to understand how much a roll of net weighs and how much a net post weighs (or what is the wall thickness). Once you understand these, no matter how many tricks the manufacturer has There is no place to hide.
Net weight: The weight of the net body is different depending on the height of the net body. Therefore, net guardrail net manufacturers often publish weight information according to their height, which is divided into 5 parts: 1 meter, 1.2 meters, 1.5 meters, 1.8 meters, and 2 meters. In each section The weight is divided under the section to distinguish the difference in quality. The weights often produced by guardrail net factories include 9KG, 12KG, 16KG, 20KG, 23KG, 25KG, 28KG, 30KG, 35KG, 40KG, 45KG, 48KG, etc. Of course, depending on the warp and weft wires, plastic powder, etc. used, Values fluctuate up and down.
Net post weight, the weight of the net post is determined by the wall thickness of the post. Common wall thicknesses include 0.5MM, 0.6MM, 0.7MM, 0.8MM, 1.0MM, 1.2MM, 1.5MM, etc. There are several heights: 1.3M, 1.5M, 1.8M, 2.1M, and 2.3M.
The surface of the mesh posts is spray-coated. There is only one type and there is no quality difference.
Net plastic coating, plastic coating refers to the surface being covered with a layer of plastic material. There is no quality difference originally, but it is different after adding an expansion agent in the production. When no expansion agent is added, a hard plastic Dutch net is produced. Add a small amount The final product produced is a low-foaming net. Depending on the amount added, the general medium-foaming net and high-foaming net are produced. So how do you know whether your product is made of hard plastic or foam? It's simple. One is to look at it with your eyes, and the other is to touch it with your hands. If you look at it with your eyes, if it is shiny, it means it is made of hard plastic. If it is dull, it means it is made of foam plastic. If you touch it with your hands, it will feel as smooth as a mirror without being astringent, and it will be particularly hard. If you touch it, it is hard plastic. If it feels astringent and slightly elastic, it is low-foam plastic. If it feels astringent and elastic, it is medium-foam plastic. But if it feels particularly soft, as if you are touching a leather strip, it is undoubtedly high-foam plastic.
