More and more users use wire mesh fence as isolation fences. Fence mesh A kind of highway steel guardrail. Its structure is to divide the original guardrail upright into two parts. The lower end of the steel pipe of the upper upright is sheathed in the upper end of the steel pipe of the lower upright. It strengthens the lower post, that is, uses casing or other processes to prevent the deformation of the lower guardrail post, and at the same time controls the deformation position of the guardrail post by partially weakening or completely weakening the upper post, so that although the force arm is reduced, the cross section The bending modulus is also reduced at the same time, thus ensuring that the anti-collision level is not lower than the original standard design.
Railway fences firstly select the finished wire drawn from high-quality wire rods; welding or weaving is mainly based on the skilled technology and operation ability between technicians and good production machinery. A good mesh is every welding Or the preparation points can be well connected; the selection of the frame should be made of high-quality angle steel and round steel, and the angle steel and round steel used for different fence mesh applications should also be different, and the overall spray plastic should pay attention to spray plastic The degree of uniformity, as well as the quality of the coating is also critical. Expressway fences are mainly used for fences in the fields of expressways, railways, airports, stations, service areas, bonded areas, open-air storage yards, ports and other fields. Its products have the advantages of beautifying the environment, ruggedness, resistance to fading, and deformation. Here is a brief introduction to some common sense you need to know about fence purchases:
First, the structure of the wire mesh fence: the fence is divided into frame type and frame type. The frame type is a frame formed by the top pipe around the steel wire mesh and connected with the column support; the frameless type is the steel wire mesh directly connected to the steel wire mesh; the price of the guardrail is also different from the price of the two different structures of the standard guardrail.
Secondly, the wire mesh fence is usually made by welding wires of different specifications. The diameter and strength of the wires directly affect the quality of the mesh. When choosing the wire thickness that suits you, the second is the welding or compilation process of the mesh. Mainly depends on the technical and operational capabilities of technical personnel and good production machinery. In general, a good mesh is that every welding or braiding point can be well connected.
Third, it is important to choose the frame structure of columns and fences. The column and frame matching should be used reasonably for a longer time. Therefore, how to choose the material of the column frame is very important. There are three different types: square steel, hexagon, and round. The strength of the boundary fence is different. The key is how to choose the material of the upright frame, which depends on the thickness of the internal column, the back tilt angle, the total weight of the amount of prepreg. These are all understood.
Forth, The surface treatment of the wire mesh fence is different from injection molding, cold galvanizing and hot galvanizing, and the quality of the plastic powder is directly related to the service life.
With the above introductions, I hope you can buy the right guardrail. Fence manufacturers remind you not to buy low-priced products, but also to pay attention to the quality of materials, because the quality of materials directly affects the quality and service life of products, and product quality.
