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.
