What kinds of guardrails are commonly used on the road?

Flexible guardrail generally refers to an elastic guardrail structure with greater buffering capacity. It is a structure fixed on a column by several cables with initial tension. It mainly relies on the tensile stress of the cable to withstand the collision and energy absorption of the vehicle. 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 guardrail usually refers to a continuous beam-column guardrail structure. This is a beam structure fixed by a bracket, which resists vehicle collisions through the bending deformation and tension of the guardrail. The beam guardrail can be divided into W-beam guardrail, tube beam guardrail, box Beam guardrails, 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 guardrail generally refers to a guardrail 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 guardrail will not deform during collision and will hardly be damaged. The maintenance cost is very low, but there is a sense of pressure on the driving of the vehicle, and it is easy to use snow in cold areas.

After the installation of the road guardrail is completed, the surface protection layer of the road guardrail net and the railway guardrail net is sprayed by zinc-rich epoxy powder and ultraviolet polyphosphate powder. The two kinds of powder spraying form a coating. Its anti-corrosion ability is other paint layers and single layer The powder layer is several times to several tens of times. It has a high technological content and is the most popular surface treatment technology in the world today.

It has the characteristics of safety and reliability, firm decoration, strong corrosiveness, easy installation, convenient transportation, maintenance-free, high strength, impact, high safety, and no pollution. It has super-strong ultraviolet light function to ensure that the product will not occur outdoors Chemical reactions such as corrosion and oxidation affect the beauty and appearance of the fence surface. The service life of the new fence meets the requirements of environmental protection.
