How to maintain traffic signs in extreme weather

Traffic signs play a vital role in cities and highways. They are indispensable safety tools to guide vehicles and pedestrians to drive and walk correctly. However, as outdoor public facilities, traffic signs need to withstand the test in harsh weather conditions such as high temperature, low temperature, strong light, and storms.

Road signsQixiang road signs use special weather-resistant reflective film, and the surface is covered with a high-density anti-ultraviolet coating. Even under high temperature exposure above 40°C, it can effectively resist fading and cracking, ensuring that the color is bright as before for 5 years; the back panel has a multi-layer waterproof coating, even if it is soaked in heavy rain and eroded by moisture for a long time, it will not rust or bulge.

Are traffic signs sun-proof? Are they rainproof?

In summer, with high temperatures and frequent heavy rains, traffic signs are very easy to be “injured”. Once the reflective film fades and the bracket loosens, it will directly threaten road safety.

High temperature is the “number one enemy” of reflective film. Long-term exposure to the sun will cause the reflective film to age and peel off, seriously affecting the clarity of the sign. Excellent traffic signs should use super-strong anti-ultraviolet reflective film, which has weather resistance far exceeding that of ordinary materials and can effectively resist ultraviolet rays. During daily maintenance, it is necessary to check the state of the reflective film regularly. If the edge is found to be warped, it should be repaired with special glue in time. At the same time, metal brackets are prone to loosening due to thermal expansion and contraction. It is recommended to reserve expansion space and use galvanized anti-rust brackets to eliminate rust hazards from the source.

The rainy season should not be underestimated either. Rainwater seeping into the base of the sign will accelerate the rust of metal parts. During maintenance, ensure that the drainage holes are unobstructed, and immediately remove rust and repaint if rust is found. In the face of extreme weather such as strong winds, early reinforcement is the key. During daily maintenance, it is necessary to check whether the anchor bolts and flanges are tightened, and add diagonal braces if necessary. In case of severe weather, the emergency repair team should respond quickly and repair the damaged signs in time.

Daily maintenance

1. Regular inspection. We need to conduct a comprehensive inspection of traffic signs regularly, including the appearance, structure and installation status of the signs. This can help us detect possible problems in a timely manner, such as looseness, damage or fading.

2. Clean regularly. Removing dust, dirt and debris from traffic signs in a timely manner can improve the clarity and visibility of the signs. Under high temperatures, these dirt may accelerate the aging and damage of the signs.
