The importance of guardrails in major cities

As people's living standards improve, private cars have become very popular. Nowadays, traffic safety has become the biggest killer on the road, and the installation of guardrail has become the most practical defense!

In fact, the installation of road guardrail most of the achievements of the traffic accident rate reduction, and residents travel safety! Road fence has become a road fence, he also has many types, according to the different stiffness can be divided into flexible fence, semi-rigid fence and rigid fence three categories

Flexible fence generally refers to a larger buffer capacity of the tough fence structure. This is a kind of structure that is fixed on the strut by a few cables exerting the initial pulling force, which mainly relies on the tensile stress of the cable to absorb the collision energy of the vehicle. Cable in the elastic range of work, basically do not need to be replaced. This kind of guardrail is beautiful, there is no feeling of oppression when the vehicle is running, but the sight induction effect is poor.

Semi-rigid fence generally refers to a continuous beam column fence structure. This is a kind of beam structure fixed by props, which rely on the bending deformation and tensile force of the guardrail to resist the collision of vehicles. Beam fence according to the different structures can be divided into W-shaped beam guardrail, tube beam guardrail, box beam guardrail and so on. They all have a certain stiffness and toughness, absorbed by the beam deformation of the collision energy, damaged parts easy to replace, with a certain line of sight induced effect, beautiful appearance.

Rigid fence generally refers to a basic deformation of the fence structure. This is a concrete wall with a certain cross-sectional shape of the wall structure, rely on car climbing, deformation and friction to absorb the collision energy. Rigid barrier in the collision does not deform, will not be damaged, the maintenance cost is very low, but there is a sense of oppression in the vehicle, easy to use snow in cold areas,

After the installation of highway guardrail, the surface protection layer of highway guardrail fence and railway guardrail product is sprayed with zinc-rich epoxy powder and UV-resistant polyester powder, and the secondary dusting forms a "permanent" coating with anti-corrosion ability of other Paint layer, single-layer powder several times to several times, belonging to high-tech, the world's most advanced high-end surface treatment technology. It has the features of safety and reliability, strong decoration, super corrosion resistance, simplified installation, convenient transportation, maintenance-free, high strength, impact resistance, high safety and zero pollution. It has super anti-ultraviolet function, Outdoors will not rust, oxidation and other chemical reactions affect the appearance of the fence surface and life, eliminating the need for cumbersome maintenance in the future, in line with environmental requirements of the new science and technology fence.
