The protective net on the bridge to prevent throwing objects is called the bridge anti-throw net. Because it is often used on viaducts, it is also called the viaduct anti-throw net. Its main function is to install it on municipal viaducts, highway overpasses, railway overpasses, street overpasses, etc. to prevent people from being hurt by thrown objects. This way can ensure that pedestrians and vehicles passing under the bridge are not injured. In such a situation Under such circumstances, bridge anti-throw nets are increasingly used.
Since its function is protection, the bridge anti-throw net is required to have high strength, strong anti-corrosion and anti-rust capabilities. Usually the height of the bridge anti-throw net is between 1.2-2.5 meters, with rich colors and beautiful appearance. While protecting, it also Beautify the urban environment.
There are two common design styles of bridge anti-throw nets:
1. Bridge anti-throw net - expanded steel mesh
Expanded steel mesh is a metal mesh with a special structure that does not affect the driver's vision and can also play an anti-glare role. Therefore, this kind of anti-glare mesh with a diamond-shaped steel plate mesh structure is the most commonly used.
The specifications of the most commonly used expanded steel mesh for anti-glare mesh are as follows:
Material: low carbon steel plate
Plate thickness: 1.5mm-3mm
Long pitch: 25mm-100mm
Short pitch: 19mm-58mm
Network width: 0.5m-2m
Network length 0.5m-30m
Surface treatment: galvanized and plastic coated.
Usage: Fencing, decoration, protection and other facilities in industry, bonded zones, municipal administration, transportation and other industries.
Conventional product parameters of expanded steel mesh used as anti-throw net:
Guardrail height: 1.8 meters, 2.0 meters, 2.2 meters (optional, customizable)
Frame size: round tube Φ40mm, Φ48mm; square tube 30×20mm, 50×30 (optional, customizable)
Column spacing: 2.0 meters, 2.5 meters, 3.0 meters ()
Bending angle: 30° angle (optional, customizable)
Column shape: round tube Φ48mm, Φ75mm (square tube optional)
Mesh spacing: 50×100mm, 60×120mm
Wire diameter: 3.0mm-6.0mm
Surface treatment: overall spray plastic
Installation method: direct landfill installation, flange expansion bolt installation
Production Process:
1. Procurement of raw materials (wire rods, steel pipes, accessories, etc.) 2. Wire drawing; 3. Welding mesh sheets (weaving mesh sheets); 4. Welding frame patches; 5. Galvanizing, plastic dipping and a series of processes. The production cycle is at least about 5 days.
2. Bridge anti-throw net - welded net
Welded mesh double-circle guardrail mesh is made of cold-drawn low-carbon steel wire welded into a mesh-shaped crimp and integrated with the mesh surface. It is galvanized for anti-corrosion treatment and has strong corrosion resistance. It is then sprayed and dipped in various colors. Spraying and dipping; the connecting accessories are fixed with the steel pipe pillars.
The metal mesh braided and welded with low carbon steel wire is stamped, bent and rolled into a cylindrical shape, and then connected and fixed with the steel pipe support using connecting accessories.
It has the characteristics of high strength, good rigidity, beautiful appearance, wide field of vision, easy installation, bright, light and practical feeling. The connection between the mesh and the mesh columns is very compact, and the overall look and feel is good; the up and down rolling circles significantly increase the strength of the mesh surface.
