The installation of highway guardrails reduces the occurrence of traffic accidents and the safety of residents' travel. Highway guardrail nets have become traffic obstacles. There are many kinds of them. According to different stiffnesses, they can be divided into flexible guardrail nets, semi-rigid guardrail nets and rigid guardrail nets Big category.

Flexible guardrail net generally refers to the elastic guardrail structure with greater buffering capacity. It is a structure fixed on the column by several cables with initial tension. It mainly depends on the tensile stress of the cable to resist the collision and energy of the vehicle. Absorption. The cable works within the elastic range and basically does not need to be replaced. This guardrail looks beautiful, there is no pressure when driving, but the visibility is very low.

Semi-rigid fence mesh usually refers to a continuous beam-column fence structure. This is a beam structure fixed by a bracket, which resists vehicle collisions through the bending deformation and tension of the fence. Beam fences can be divided into W-beam fences and tube-beam fences. , Box girder guardrail, etc. They all have a certain degree of rigidity and toughness, absorb impact through the deformation of the beam, easy to replace damaged parts, have a certain line of sight induction, and have a beautiful appearance.

Rigid fence generally refers to a fence structure that is basically non-deformable. This is a cement concrete wall structure with a certain cross-sectional shape, which absorbs collision energy through climbing, deformation and friction. Rigid fence will not deform during collision and will hardly be damaged. .Maintenance costs are low, but there is a sense of pressure on the driving of the vehicle, and it is easy to use snow in cold areas.
