Bilateral wire fence, highway and railway isolation fence, impregnated iron wire fence

Description :

  Bilateral wire fence is a structurally simple and widely used metal isolation and protection product, mainly used to solve the problems of regional boundary delineation, safety protection, and prevention of human and animal intrusion. It is welded by high-quality low-carbon steel wire, and its surface is treated by dipping plastic or galvanizing. It has the characteristics of corrosion resistance, aging resistance, simple installation, etc. Typical working conditions include enclosure protection for highways, railways, airports, ports, municipal green spaces, garden flower beds, unit green spaces, and residential areas. This product has become one of the most commonly used forms of guardrails in the market due to its low cost, good transparency, and wide field of view, which can effectively meet the long-term protection needs of various outdoor environments.

  The specification parameters of double-sided wire fence usually vary according to different usage scenarios. The common wire diameter range is 3.5mm to 6.0mm, and the mesh size is mostly 90mm × 170mm or 80mm × 160mm. There are also specifications such as 50mm × 200mm to choose from. The columns are usually made of round pipes with a diameter of 48mm or 60mm, with a wall thickness between 1.5mm and 2.5mm, and a height of generally 1.8 meters or 2.0 meters. They can also be customized according to customer requirements. The surface treatment process mainly includes hot-dip galvanizing, cold galvanizing, spray coating, and immersion coating. The thickness of the immersion coating is usually between 0.5mm and 1.0mm, and the colors are mainly green, white, and blue. Refer to relevant national standards such as GB/T 26941.3-2011 "Barrier Part 3: Welded Mesh" to ensure that the mechanical and anti-corrosion properties of the product meet the standards.

  When selecting, it is necessary to clearly distinguish the differences between double-sided wire fence and frame fence, as well as triangular bent fence. The double-sided wire fence has no frame support and relies on columns to directly fix the mesh, which has the lowest cost and is suitable for large areas with limited budgets; The frame guardrail net has a frame and higher strength, suitable for places with high stability requirements; The triangular bent guardrail net has better aesthetics and is suitable for areas with high municipal landscape requirements. If used in high-intensity impact risk areas such as highways, it is recommended to increase the wire diameter or choose a frame structure; If only used for low-intensity isolation in orchards, farms, etc., standard specifications of double-sided wire fence can meet the needs. When making a purchase, special attention should be paid to the firmness of the solder joints, the uniformity of the plastic layer, and the thickness of the column wall, to avoid using recycled materials or non-standard products that may shorten the service life.

  When installing double-sided wire fence, the first step is to determine the position of the columns, usually with a spacing of 3 meters. After excavating the foundation pit, the columns are placed and fixed with concrete. After the concrete solidifies, the mesh is fixed to the columns with anti-theft screws or buckles. In daily maintenance, it is necessary to regularly check whether the connectors are loose and whether the plastic layer is damaged. If rust or breakage is found, it should be repaired or replaced in a timely manner to prevent corrosion from spreading and affecting overall stability. In environments with strong acidic and alkaline corrosiveness, it is recommended to choose products with dual anti-corrosion treatment of hot-dip galvanizing and dipping plastic. Common faults include deformation of the mesh and tilting of the pillars, which are often caused by external impact or weak foundations. When repairing, it is necessary to recalibrate the pillars and reinforce the foundation to ensure the overall protective function of the guardrail remains effective.
