What are the commonly used materials for road guardrails
1、 Steel guardrail
Steel guardrails can be said to be the most common material in road guardrails because they can provide good collision protection performance and have a long service life. Due to its high strength and corrosion resistance, as well as easy processing and maintenance, steel has become one of the preferred materials for road guardrails.
2、 Aluminum alloy guardrail
Aluminum alloy guardrail is another common road guardrail material, which is lighter than steel guardrail and has good corrosion resistance and oxidation resistance. Aluminum alloy guardrails can also achieve multiple color choices through surface treatment, thereby better eliminating traffic obstacles.
3、 Fiberglass guardrail
Compared to steel and aluminum alloy guardrails, fiberglass guardrails are lighter and tougher, while also having good corrosion resistance and UV resistance. However, its price and cost are relatively high, and it is usually only used for road guardrails in important roads or special scenarios.
4、 Plastic guardrail
Plastic guardrail is an environmentally friendly, easy to install and maintain road guardrail material. Due to its relatively low material cost, the price is relatively affordable and very suitable for some urban construction projects.
