The protective net on the bridge to prevent throwing is called the bridge anti-throwing net. Because it is often used on the viaduct, it is also called the viaduct anti-throwing net.
Its main role is to install in the municipal viaduct, highway overpass, railway overpass, street overpass, etc., used to prevent hurling, this way can be very good to ensure that pedestrians passing under the bridge, vehicles are not hurt, in this case, the application of bridge anti-throwing net is more and more.
Because of its function for protection, so it requires the bridge anti-casting net strength is high, anti-corrosion, anti-rust ability is strong, usually bridge anti-casting net height between 1.2-2.5 meters, rich color, beautiful appearance, at the same time of protection, but also beautify the urban environment.
There are two common design styles of bridge anti-throwing nets:
1. Bridge anti-throwing net-expanded steel net
Metal mesh with special structure, such as steel mesh, does not affect the driver's line of sight, but also can play the role of anti-glare, so this kind of anti-glare mesh with diamond-shaped steel mesh structure is the most commonly used.
Generally, the specifications of expanded metal for anti-glare nets are as follows:
Material: low carbon steel plate
Plate thickness: 1.5mm-3mm
Long pitch: 25mm-100mm
Short pitch: 19mm-58mm
Net width: 0.5m-2m
Net length 0.5m-30m
Surface treatment: galvanized and plastic-coated.
Uses: fences, decorations, protection and other facilities in industries, bonded areas, municipalities, transportation and other industries.
Conventional product parameters of expanded metal mesh used as anti-throwing mesh:
Guardrail height: 1.8m, 2.0m, 2.2m (optional, customizable)
Frame size: round tube Φ40mm, Φ48mm; square tube 30×20mm, 50×30 (optional, customizable)
Column spacing: 2.0m, 2.5m, 3.0m ()
Bending angle: 30° angle (optional, customizable)
Column shape: round tube Φ48mm, Φ75mm (square tube is optional)
Mesh spacing: 50×100mm, 60×120mm
Wire diameter: 3.0mm-6.0mm
Surface treatment: overall plastic spraying
Installation method: direct landfill installation, flange expansion bolt installation
Production Process:
1. Raw material procurement (wire rod, steel pipe, accessories, etc.) 2. Wire drawing; 3. Welding mesh (weaving mesh); 4. Welding frame patch; 5. A series of processes such as galvanizing and dipping. The production cycle is at least about 5 days.
2. Bridge anti-throwing mesh - welded mesh
Welded double-circle fence net is welded with cold-drawn low-carbon steel wire to form a cylindrical curling and 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; connecting accessories and steel pipe pillars are fixed.
The metal mesh welded by low-carbon steel wire is punched, bent and rolled into a cylindrical shape, and then fixed with the steel pipe pillar by connecting accessories.
It has the characteristics of high strength, good rigidity, beautiful shape, wide field of vision, easy installation, bright, light and practical feeling. The connection between the mesh and the net post is very compact, and the overall appearance is good; the upper and lower coils increase the strength of the mesh surface significantly.
