Basic specification properties of 8001 type railway protective fence metal mesh:
The cost of dip-coating after galvanizing wire welding is relatively low, but galvanized wire may damage the zinc layer when welded, so the anti-corrosion effect is relatively unsatisfactory. use
It is mainly used for the protection belts on the highways, railways and bridges; the security protection of airports, ports and terminals; the isolation and protection of parks, lawns, zoos, lakes, rivers, and residential areas in municipal construction.
Characteristics
1. The column is made of concrete castings, and the construction cost is low. 2. High strength The overall stability is good. 3. The color plastic layer has good corrosion resistance and decorative effect. 4. The net perimeter is harmonious and beautiful. 5. Railway closure, highway guardrail, development zone perimeter, field fence. 6. Anti-corrosion, anti-aging, anti-sun and other characteristics. Common specifications of railway fence net: net height x net width: 1700 (mm) * 2760 (mm) wire diameter range (plastic front): 4.0 (mm) with mesh hole size (common): 75 * 150 (mm) frame ( Before plastic:) 30*50*2.0 (mm) railway fence network construction should pay attention to the problem 1. The construction unit should accurately grasp the various construction drawings when installing, for the exact location of the various pipes buried in the roadbed No damage to the underground facilities is allowed during the construction process. 2. If the column is driven too deep, the column should not be pulled out for correction. It is necessary to re-compact the foundation and then enter it, or adjust the position of the column. Pay attention to controlling the hammering force when approaching the depth during construction. For the railway guardrail, the flange should be installed, pay attention to the positioning of the flange and the control of the top level of the column. 3. The railway fence network is the safety installation of the railway and is an important part of the appearance quality of the expressway. The inherent quality of the railway fence network lies in the raw materials and processing process. Its appearance quality depends on the construction process. The construction should pay attention to the combination of construction preparation and pile driver, continuously sum up experience and strengthen construction management, which guarantees the installation quality.
