(1) The corrugated guardrail beam should not have obvious torsion, nor should it be welded or lengthened, and the end burrs must be removed. The layout of columns is based on the control points on the highway, and the spacing between columns is adjusted appropriately according to the measurement distance; The installation of columns should be consistent with the design drawings and coordinated with the road alignment.

There are a total of 6 types of components for guardrail beam, including columns, anti blocking blocks, guardrail beam brackets, end caps, column rain caps, and bolts. The role of each component is very important, and the lack of any component cannot achieve effective protective effects.Guardrail beam columns can be divided into galvanized columns, dipped plastic columns, flange columns, ordinary columns, etc. There are various diameters of columns, and suitable diameters and thicknesses can be selected according to engineering needs.

The highway guardrail is composed of two corrugated steel guardrail panels and two fixed columns clamped between them. The two columns are fixed and clamped between the two corrugated steel guardrail . During normal operation of highways, highway guardrail can be easily inserted into the pre-set insertion holes at the openings using plug-in columns, providing isolation and protection.

Firstly, in the initial design and installation process of highway guardrail, it is necessary to strictly follow relevant standards and specifications. The installation of columns must be firm, buried underground to a depth that meets the design requirements, and kept perpendicular to the horizon.Secondly, there are various methods for installing highway guardrail, but regardless of which method is used, efforts should be made to avoid damaging the underground pipelines and pipeline facilities of the highway.

1. During production and processing, it is necessary to first lay out the sample and create a template. The template needs to be strictly produced according to the customer's needs.2. The kneading deformation process of corrugated guardrail beam: The guardrail beam is divided into two wave guardrail beam, three wave guardrail beam, and two wave three wave transition boards, which are processed using different production equipment.3. The anti-corrosion treatment effect of galvanized corrugated guardrails must be good.

① Inspection method: When preparing for the inspection, the inspection personnel should carefully inspect the technical condition of the inspection vehicles and communication equipment, verify the handover records of the inspection, and develop an inspection plan. During the inspection of guardrail beam, vehicles should be illuminated according to regulations, and the speed should generally be controlled at 40km/h. Pay attention to the changes in the technical conditions of the highway and keep records of the inspection of key structures and road sections.

Raw material prices: The main raw materials for guardrail beam is metal materials such as steel, aluminum, stainless steel, etc. The price fluctuations of these materials will directly affect the price of guardrail beam. The fluctuation of raw material prices is often influenced by various factors, such as market supply and demand, trade policies, natural disasters, etc.Technical difficulty: The production difficulty of different types of guardrail beam varies, and complex design and processing techniques can increase manufacturing costs, leading to an increase in the price of guardrail beam.

Firstly, the price of guardrail beam mainly depends on their production cost. This includes the cost of raw materials, processing costs, as well as transportation and storage expenses. Among them, the cost of raw materials accounts for the main part of the price of guardrail boards. Generally speaking, the material used for guardrail beam is mainly steel, so the price fluctuations of steel will directly affect the cost of guardrail beam.Secondly, processing costs are also an important component of the price of guardrail beam.

The spray coating anti-corrosion treatment of highway guardrail adopts electrostatic spray coating instead of traditional immersion treatment. Electrostatic spray coating is also known as electrostatic powder spray coating. Even if the powder is uniformly adhered to the highway guardrail under electrostatic action, this process does not require diluents, which is more environmentally friendly, harmless to human health, and waste free.

1. Separation function: Guardrail beam separate motor vehicles, non motor vehicles, pedestrians, and traffic spaces, and analyze the longitudinal horizontal separation of roads on cross-sections, allowing motor vehicles, non motor vehicles, and pedestrians to move in separate lanes, improving the safety of traffic development in China and improving traffic management order.2. Obstacle effect: Traffic obstacles can hinder bad traffic behavior, such as pedestrians, bicycles, or motor vehicles attempting to cross the road.
