Qixiang, a Chinese traffic safety facility supplier, believes that road steel guardrails are a widely used road safety features. When impacted, they effectively absorb the force of collisions, significantly minimizing damage to vehicles and pedestrians in the event of an accident. Urban roads are constantly visited by vehicles, day and night, requiring constant protection from guardrails. Metal guardrails, exposed to the elements year-round, can rust. To prevent rust, they require a surface treatment with either plastic spraying or hot-dip galvanizing.
If the corrosion resistance of guardrails is poor and the quality is substandard, even relatively young guardrails can develop cracking and rust, creating an unsightly, aged appearance that detracts from the overall highway’s visual appeal. The idea that simply because guardrails perform well doesn’t require maintenance is incorrect. Even guardrails made of high-quality materials require routine maintenance.
Daily Maintenance of road steel guardrails
road steel guardrails are subject to constant exposure to the elements year-round, making their maintenance extremely important. Today, I’ll explain some key points to keep in mind when maintaining road steel guardrails.
1. Avoid scratching the surface coating of road steel guardrails with sharp objects. Generally, the coating prevents rust and corrosion. If you need to remove a section of the guardrail, be sure to reinstall and secure the remaining section.
2. If the outdoor air humidity is normal, the guardrail’s rust resistance is reasonable. However, in foggy weather, use a dry cotton cloth to remove any water droplets from the guardrail. If it rains, wipe the guardrail dry immediately after the rain stops to ensure the zinc steel guardrail is moisture-proof.
3. To prevent rust, regularly wipe the surface with a cotton cloth dipped in a small amount of rust-proof oil or sewing machine oil to keep the wrought iron railing looking like new. If you notice rust on the railing, apply a cotton cloth dipped in machine oil to the rusted area as soon as possible. This will remove the rust. Avoid sanding with sandpaper or other rough materials. 4. Regularly remove weeds and debris from around the guardrail. Wall-type concrete guardrails should ensure they can extend and retract freely.
5. If a guardrail is deformed due to a traffic accident or natural disaster, it should be promptly corrected and adjusted.
6. Clean the guardrail regularly (once a year, unless otherwise specified) to ensure a smooth, contamination-free surface.
Traffic safety facility supplier Qixiang reminds you of some precautions regarding road steel guardrails:
1. If the guardrail is severely damaged, it must be removed and replaced.
2. If the guardrail is deformed due to an impact, repairs may require digging up the roadside, using a gas cutter to straighten the bends, heating and straightening them, and then welding them securely.
3. For minor damage, guardrails may require only minor repairs before continued use.
4. Guardrails provide an additional layer of protection for drivers, so maintenance is paramount.
