Urban guardrails play a very important role in cities
With the improvement of people's living standards, private cars are becoming increasingly popular. Nowadays, traffic safety has become a killer on the road, and the installation of guardrails has become a practical defense method!
In fact, the installation of urban guardrails greatly reduces the incidence of traffic accidents and lowers the safety of residents' travel. Highway guardrails have become various types of highway guardrails. According to stiffness, it can be divided into flexible guardrails, semi-rigid guardrails, and rigid guardrails.
Flexible guardrails generally refer to hard guardrail structures with significant buffering capacity. This is a structure fixed on a pillar by several steel cables with initial tension. It mainly relies on the tensile stress of the cable to resist collisions and absorb the energy of the vehicle. The cable works within the elastic range and basically does not need to be replaced. This type of guardrail has a beautiful appearance and no sense of pressure when driving, but its visual guidance effect is poor.
Semi rigid guardrails generally refer to continuous beam column guardrail structures. This is a beam structure with fixed pillars that relies on the bending deformation and tension of the guardrail to resist vehicle collisions. According to their different structures, beam guardrails can be divided into W-shaped corrugated beam guardrails, pipe beam guardrails, and box beam guardrails. They all have a certain degree of stiffness and toughness. They absorb collision energy through the deformation of the light beam. Damaged parts are easy to replace. Has a certain visual induction effect and a beautiful appearance.
Rigid guardrail generally refers to a basic non deformable guardrail structure. This is a concrete wall structure with a certain cross-sectional shape that absorbs collision energy through car climbing, deformation, and friction. Rigid guardrails do not deform during collisions, are almost undamaged, and have low maintenance costs, but they can create a sense of pressure on the vehicle's movement. It is easy to snow when used in cold regions.
After the installation of urban guardrails, zinc rich epoxy powder and UV resistant polyester powder are sprayed on the surface protective layer of highway and railway guardrails, forming a "long-lasting" coating. Its anti-corrosion ability is several tens of times that of other coatings and single-layer powder coatings, which belongs to high-tech content and is one of the highest in the world today.

Set up some speed reduction signs on the road surface with cast steel speed bumps
Set up some speed reduction signs on the road surface with cast steel speed bumps
Cast steel speed bumps are installed on the road surface with some speed reduction signs. Gas station vehicles frequently appear, so speed limit signs, collision barriers, speed reduction zones and other facilities will be set up at the station to remind the station to slow down and protect the safety of personnel and equipment. Especially, it is necessary to install speed reduction gas stations. So, we will further discuss this topic on which speed reduction zone to choose and which suitable location to install. Below, I will share some of your opinions to explore. Many driving friends often encounter different types of deceleration zones, and there are mainly the following types of cast steel speed bumps:
1. Cast steel speed bumps, commonly found at village intersections, have low construction costs but are on the high side with low color rendering. The color is similar to the road surface and visually unclear, causing emergency braking, jolting, and even hitting the chassis when driving in front. 2, Cast steel speed bumps are commonly found in workplace squares, residential areas, and other places, with a height of about 5 centimeters above the ground. They are generally fixed to the ground with M12X14 sleeve expansion screws, which are yellow and black in color, visually obvious, and not expensive. However, their service life is short, and rubber speed bumps are often exposed from screws and long screws, which can easily damage tires. To replace the ground, a new speed bump needs to be repaired and fixed to the ground.
3. Cast steel speed bumps are commonly found at highway intersections, toll stations, and other places. Rubber speed bumps with better service life are superior to rubber speed bumps, but their price is much higher.
4. Paving bricks in point like deceleration zones are commonly found on highways, urban roads, and other fast roads. This type of deceleration is slightly higher than that of roads, forming a film and generally using glass bead primer and paint. They are beautiful, wearable, and have visibility at night. When vehicles walk on them, they emit a strange whistle sound to remind drivers to slow down.
5. Reflective hot melt marking speed reduction zone. Just like the difference in speed reduction compared to the same material, the production process is different from that of a cross highway strip. There is a distance between each line, with intermittent vibrations above to remind drivers to slow down.
