In the usual days, we often see waveforms on the two ends of the road, so how many people really understand the waveform sheet board, and how many people are truly clear about the importance of the waveform sheet board.
First of all, we need to understand the raw materials of the wave -shaped fence board. It is made of galvanized steel plates and spliced with each other with a ripple -shaped shape. The intention is to prevent the road out of the way out of the way. , Deformation of the column to absorb the energy of bumps, use this method to force the out of control to change the direction, make it recover to the normal travel track, and then maintain the safety of passengers. It is complementary to the road, and the contrast is sensitive, and the maintenance is very simple. The damage is simply replaced.
On July 18, 2013, there was a traffic incident on the intersection of Haichuan Road and Yuanyuan Road, Jining City. In the future, the injured person was taken to the hospital at the first moment. The casualties, according to the investigation, the reason for the investigation is because the two vehicles collided. A school bus directly rushed to the wave -shaped guardrail board on the roadside. Once out of the road, once the road is rushing out of the road, not only the casualties in the car are difficult to ensure, the innocent pedestrians on the road will also be harmed because they can't escape. Then this will be a very serious matter. Once you encounter dangerous self -rescue talents, it is also very low, and how many families should be broken.
From this work, we can feel the importance of the waveform guardrail. Although some safety protection equipment usually looks inconspicuous, once the attack is incident, but the life -saving straw that maintains our lives, we must have public morality in the usual days. The heart, to maintain transportation equipment, uninterrupted or damaged road traffic equipment, not only to maintain the safety of others, but also to maintain ourselves.
When it comes to the guardrail board, we can all think of the hot -dip galvanized guardrail board and plastic fence board. So is there these two ways to anticorrosion on the guardrail board? It was not. There were several anti -corrosion methods of the guardrail board, including hot -dip galvanized guardrails, aluminum -plated fence boards, galvanized aluminum alloy fence boards, plastic fence boards, and plastic railing boards.
What kind of anti -corrosion methods to compare from these anti -corrosion methods are good? Many people think that the anti -corrosion method of the hot -dip galvanized fence board is good. It was not. The anticorrosive method was a galvanized aluminum alloy fence board, which could have a service life of up to decades. Some local requirements for beauty are high. After using galvanized aluminum alloys, plastic spraying is used, which will become more solid.
The plastic fence board is also a good choice, which can turn the fence plate into various colors. The anti -collision level of the fence board is able to divide the guardrail board into A -level guardrail and S -class fence board. The anti -collision level of the A -level guardrail is generally installed on the highway. Select S -Class fence boards in some unimportant villages.
Some local rainfall comparison and strong acidic environment are strong. The service life of ordinary hot -dip galvanized guardrails will be greatly reduced. It does not reach the expected moment, so we usually choose hot -dip zinc and spray plastic.
