In general, the Lighting Guard rail is made of high-quality wire rods, which are drawn out and processed. The Lighting Guard rail is made by welding or weaving, the quality of the lighting guardrail mainly depends on the proficiency of the technical personnel, as well as the operating ability of the production machinery. Therefore, a good lighting guardrail is that every welding is very solid, and the preparation points of the light guardrail can be connected very well; the material selection of the light guardrail frame is also very good, in general, high-quality angle steel and round steel should be selected for processing, so the reputation of the light barrier is very good. Lighting Guardrail Features: This column is the use of concrete burning building parts, the cost of the project is relatively low. Light Guardrail must be made of high-quality low-carbon steel wire welded by wire, if other thin wire to welding quality is not guaranteed. For the fence surface treatment is also very important, must do a good job to prevent rusting dip. In recent years, many places in China have used the guardrail net as a fence. Generally speaking, the guardrail net is used for many purposes, such as the fencing of municipal green space, roads, airports and harbors, railway closed network, highway closed network, field fence, residential fence, isolation and protection. Lighting guardrail product specification: 1.8 m high, 2.0 m long 3 m column Mesh 7 cm 17 cm. In order to enhance the corrosion resistance of products generally have to be surface treatment, the surface of steel wire galvanized, zinc on 270 grams / square meters, and then hot-dip treatment, coating uniform smooth, color consistent. The installation of the lighting guardrail is quite strict. Its main project content is the installation of the columns and the net pieces. Before the installation of the lighting guardrail, the net pieces and the columns of the lighting guardrail must be transported to the construction site. At the same time, the construction unit shall submit the product qualification certificate and Related Materials to the supervision engineer, and the supervision personnel shall have the right to inspect the lighting guardrail net and column with quality problems. At the same time, the supervisor should check the bending degree of the metal column which is transported to the construction site, clear the metal column which has obvious deformation, scratch and the problem of curling. The railway protective fence generally adopts the frame type protective fence. The frame-type protective fence is a kind of ideal metal net wall, which has the characteristics of beautiful and durable, no deformation, convenient installation and so on. The Light Guardrail Related Construction Unit should release the standard Middle Line according to the approved construction plan and the design drawings, and clean up the construction now to ensure the beauty and fluency after the light guardrail installation. Before the foundation concrete is poured, the size of the foundation pit and the spacing between the foundation pits must be checked and approved by the supervision engineer before concrete is poured. Lighting Guardrail column in the installation process must ensure that the column of stability, and the foundation of the close connection, if necessary, can be installed support to stabilize the column. In the process of column installation, small wires are used to measure the straightness of column installation and adjust the part. Make sure the straight line segment is straight and the curve segment is smooth. The buried depth of the column should meet the requirements of the design drawings. After the completion of the column construction, the supervision engineer should check the column alignment, depth, height, and the stability of the foundation connection. After meeting the requirements, can be linked to the network construction.
