highway guardrail parts contains highway guardrail,post,spacer,end terminal ,fish tail,highway guardrail parts have many different specification.

The rapid development of expressways in China has been used extensively in highway guardrail parts. In -2010 in 2000, the new construction and expansion of various kinds of Expressway in China was 5 million kilometers, and it became the longest country in the world highway. With the rapid development of the domestic expressway construction, the domestic highway guardrail net market has been expanding. But because the production and use time of the guardrail products in our country is less than 20 years, and less than 10 years have been issued for various production standards according to the standard standard, some small manufacturers have different mastery of the performance, technical parameters and production process of the guardrail net, which causes the quality of the product to be bad and bad. In some sections, due to the use of anticorrosion technology to deal with improper guardrail products, the road guardrail net is rusty spot in one or two years, which not only affects the visual effect of the highway, but also greatly shortens the effective use period of the guardrail, but also increases the maintenance cost.

What we usually say is that the fence refers to the guard vehicles set off the roadbed along the roadbed edge of the dangerous section and the protection of the vehicles against the road, as well as the safety of pedestrians in isolation of pedestrians and vehicles. It has the vision of inducing the driver, causing alertness or restricting pedestrians' arbitrary crossing. The guardrail consists of pillars and bars, which can be made from wood, reinforced concrete or metal. In the early days of the fence application, paint protection was usually applied, and then gradually hot dip zinc was used.

highway guardrail parts is a large and long-lasting facility for outdoor use. The selection of protection system should choose different protection systems for different atmospheric environment. The newly promulgated national standard GB/T18226-2000 "anticorrosion technical condition for highway traffic engineering steel structure", the protection of highway guardrail net products is divided into four categories: galvanized, aluminized, galvanized (aluminum) after coating and coating. In rural areas and areas where pollution is not serious, separate hot dip zinc layers can be used to protect or spray protective guardrails.

In heavy industrial or coastal urban areas, especially in areas with acid rain, ordinary hot dip zinc or plastic sprayed single coated guardrail may lose its utility, resulting in the maintenance of a road guardrail net. This has greatly increased. The corrosion resistance of hot dipped aluminum guardrail is better than that of hot dip galvanized barrier, but its technology, technology, cost and environmental impact are not widely used.

The hot dip aluminizing + plastic spray protection system is an uneconomical method for the protection system of hot dip zinc + plastic sprayed. The dual protective system of galvanized plate and spray can achieve better anticorrosion effect in heavy polluted areas, especially in acid rain area, and the service life is greatly extended and the most durable protection method can be used.

Performance and characteristics of highway guardrail parts:

The highway guardrail parts is the most important traffic infrastructure. The highway in China developed from 80s. It plays an important role in the development of the national economy and the society. It is an important maintenance and safety protection facility for the highway.

Material: use low carbon steel wire, spray plastic. Knitting and characteristics：

The mesh structure is concise, convenient for transportation and installation, and is not restricted by terrain undulation, especially for mountainous, sloping and multi bend areas. This product is sturdy and durable, and its price is medium and low. It is suitable for the product features of large area road fence.

highway guardrail parts have beautiful, durable, non deformation and fast installation. It is an ideal metal barrier product. It can be made into permanent net wall, and can be used as a temporary isolation network. It only needs to be fixed by different vertical columns. It has anti-corrosion, anti-aging, anti sun and weather resistant characteristics. For anticorrosive forms, electroplating, hot plating, plastic spraying and plastic dipping can be used. Uses and uses: mainly used for parks / Zoo fences, campus / field area, road traffic isolation, temporary isolation belt.

highway guardrail parts specifications and characteristics

In order to further strengthen the maintenance work of the highway guardrail parts in the flood season, stabilize the road conditions, repair the wave guardrails along the damaged highway and ensure the safe and smooth road, the Huaian highway department forwarded the notice of the Highway Bureau of the Jiangsu provincial transportation department to the relevant units in time to improve the maintenance work of the flood season, so that the units should be carefully studied. We should pay great attention to the implementation, pay great attention to the maintenance work of the wave guardrails in flood season, prepare the emergency materials for emergency emergency rescue in flood season, strengthen the inspection and inspection of highway maintenance in flood season, strengthen the regular inspection of the bridge, do a good job of highway water destruction and repair work in time, and strengthen the maintenance and safety management of the road wave guardrail. The highway is safe and unimpeded. Strictly implement the 24 hour duty system and lead class system, establish and improve the information network, unimpeded information channels, to ensure the uploading of all kinds of information and emergency instructions.

According to the different location of the guardrail, highway guardrail parts is divided into a wave guard fence and a central divider fence.

highway guardrail parts is divided into B\A\SB\SA\SS five levels according to the collision prevention grade, a grade is used for special highway, and the S barrier is a reinforced type. It is suitable for the use of road side especially dangerous section. The central partition guardrail is divided into Am, SAm, SBm three levels and according to the different grade of traffic accidents on the expressway, we use different waveform guardrails, general accidents or major accidents A, Am. Bicycle accidents or two major accidents SB, SBm. The two great accident SS.

The thickness of the highway guardrail parts is 3mm and 4mm, the length of the board is 4320mm, and the width of the board is 310mm. Each 3mm thickness guardrail is 49.16kg, and each 4mm thickness guardrail is 65.55kg.
