Introduction to the components of guardrail beam

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 guardrail beam is fixed on the roadbed and integrated with the roadbed to achieve a common protective effect.

The role of rain caps on guardrail columns is also very important. Without rain caps, a lot of rainwater will accumulate inside the columns, and there are many acidic ions in the rainwater. Even the columns with the best anti-corrosion effect will fly and corrode in the long term.

Generally, one of the options for anti blocking and bracket is to link the corrugated guardrail beam with the column. The protective effect of the anti blocking is higher than that of the bracket, because the deformation of the anti blocking is greater, and the deformation of the components can slow down the power of the car.

The usage of guardrail beam ends is relatively small. Install one at both ends of each group of guardrail beam to make each group of guardrail beam looks more beautiful.

There is no need to introduce the bolts of the guardrail beam. It is also very important to mainly introduce the anti-corrosion performance of the bolts. Bolts with good anti-corrosion performance can greatly improve the service life of the guardrail beam.
