Key details and surface coating considerations for assembling highway guardrails
The selection of raw materials for highway guardrails should consider various factors such as harmony with the landscape, compatibility with existing nets or iron nets, ease of construction, and anti-theft systems. It should also adapt to local conditions and utilize local materials. Guardrails are practical protective products. What are the different installation steps and how should guardrails be installed to provide certain protection during assembly? What should be paid attention to during installation?
Guardrail installation and fixing: You need to choose between embedded installation or cement casting assembly. These installation methods are different. The chassis positioning device often requires a good concrete foundation.
Highway guardrails have three types of surface coatings:
Hard plastic guardrail with high-density hard plastic, tightly combined with stainless steel wire, leaving no marks when scratched by nails, and a delicate surface. Therefore, the coating should not be too thick, generally about 0.3mm. Although the price is slightly higher, it is durable. The pore size after plasticizing is tiny, which sounds like a low performance-to-price ratio, but the fact is just the opposite.
Low-foaming highway guardrail with several types of foaming agents added to the metal powder, resulting in a metal powder thickness of 0.6mm. The surface is dull, the plastic layer's connection to the stainless steel wire is average, and steel nails leave shallow scratches.
Electrostatic powder for highway guardrails contains more foaming agents and has a lower density. The foamed plastic powder, like popcorn, makes the metal powder expand. Although it looks thick on the surface, its internal structure is weak, its service life is short, and cracks may appear after a period, making it difficult to use normally. Therefore, it is mainly used for temporary projects like Luanping and reconnaissance.
Application effects of highway guardrails:
1. Good visual impact of the product, creating a clean and tidy psychological effect for people.
2. Provides assistance for road traffic or pedestrian travel, saving time and effort, and maintaining road order.
3. This product can play a deterrent role during night driving, reminding drivers to pay attention to safety and reduce the occurrence of incidents.
4. It can improve the utilization of highway areas and expand visibility.
5. Highway guardrail networks are mainly used in urban highway landscaping, railway lines, farms and schools, airports and prisons, near bridge construction sites, power station enclosures, etc.
The industry outlook is good. Users who have used the product early have already experienced the benefits brought by the product. Frame guardrail (frame fence) uses wire as the main raw material, and through hot-dip galvanizing and PVC coating of the mesh, it has long-lasting corrosion resistance.
