As we all know, since the road guardrail has been used outdoors, the outdoor dust is flying, and after a period of time, a layer of floating dust will fall. If it is not cleaned for a long time, it will affect the appearance of the guardrail. Not only that, dust pollution can also affect the color of the guardrail, which in turn leads to damage to the surface protective film. So in this case, our top priority is to beautify the road guardrail.
The first step is to use cleaning to keep the surface of the guardrail clean.
When cleaning the guardrail, try to choose a soft brush. Now the guardrail on the road is basically cleaned by the guardrail cleaning car. The soft brush design does not leave a dead corner and does not scratch the paint surface.
The second step, timing check processing
Check the guardrails of each section regularly to prevent damage to the fence. The main reason for this step is to be able to repair the damage of the road section in time to ensure their normal use.
The third step, pay attention to moisture and moisture
Although the maintenance of the guardrail on the road is not fine enough, due to environmental pollution, acid rain is raging in most areas, so it should be washed again after heavy rain. If it's just normal weather, you don't have to be so troublesome.
