Railway guardrails are crucial traffic infrastructure, demanding higher standards of safety and practicality. The posts are available in galvanized steel pipes, peach-shaped posts, dovetail posts, and C-shaped steel, while the mesh options include plastic-coated wire mesh, PVC-coated welded wire mesh, knitted mesh, steel mesh, and perforated mesh. The general structure consists of posts and frames connected by fasteners, which can also be directly connected to posts using mesh clips, bolted connections, or riveted fasteners, allowing for adjustable angles.
Material Selection:
Low-carbon steel wire
Knitted:
Welded construction; grid structure is concise, easy to transport, and installation is not restricted by terrain undulations. Especially adaptable to mountainous, sloping, and winding areas.
Manufacturing Process:
Firstly, select the finished wire drawn from the coil; welding or weaving is primarily dependent on the skilled techniques and operational capabilities between technicians and production machinery. A good mesh panel ensures that every welding or weaving point is well connected. Additionally, when selecting materials for the frame, opt for high-quality angle iron, flat steel, and round steel. The choice of angle iron and round steel for different applications of the fence mesh should also vary. In terms of surface treatment, attention should be given to the evenness of the protective film. Moreover, the quality of the raw materials for the protective film is crucial.
Application
Railroad Guard Rails/Protective Fencing, also known as Railroad Protective Fencing, comes in two types: Bridge Railings (Line 2012-8001) and Under Bridge Railings (Line 2012-8002). Primarily used for protective strips alongside highways, railways, and bridges; for safety at airports, ports, and docks; and for isolation and protection in public construction projects such as parks, lawns, zoos, ponds, roads, and residential areas.
Advantages:
1. Columns are cast in concrete, resulting in low construction costs.
High strength, excellent overall stability.
3. The colored plastic layer offers excellent corrosion resistance and decorative effects.
4. Overall harmony and aesthetics.
5. Corrosion-resistant, anti-aging, and UV-resistant features.

Issues to be Aware of When Installing Railings for Railway Fence Net
1. During installation, the construction company must accurately understand the construction drawings. Any pipeline buried in the subgrade must be positioned precisely, and no damage to underground facilities is permitted during the construction process.
2. If the pillar is driven too deep, do not pull it out to correct; instead, recompact the foundation before driving it in again, or adjust the pillar's position. During construction, be mindful of controlling the impact force as you near the desired depth. For railway guardrails, install flanges and pay attention to the positioning of the flanges and the control of the pillar top elevation.
3. Railway guardrail systems are an essential safety installation project for railroads and are a significant part of the appearance quality of expressways. The intrinsic quality of railway guardrails lies in the raw materials and processing, while their appearance quality depends on the construction process. It is crucial to pay attention to the preparation of construction work and the combination of pile drivers, continuously summarize experiences, and enhance construction management to ensure the installation quality.
