Classification and production requirements of railings and guardrails

This paper will introduce the classification and production requirements of railings and guardrails to help readers better understand these two facilities.

Classification of railings

Railings are classified according to height, material and form. The height standard design is 1.0m, generally 0.8 ~1.2m. According to the material classification, there are reinforced concrete, steel, mixed, masonry, wood and plastic, and according to the form, there are internodes (columns are set for each section of 1.6 ~ 2.7m) and continuity.

Requirements of railing production

The production of railings requires sufficient cross-sectional size and embedding depth, and the railings at expansion joints can be deformed freely, and the strength only considers the force generated by people leaning on the railings.

Guardrail setting position

The guardrail is located at the bridge side, the central isolation belt and the boundary between people and vehicles.

Classification of structural characteristics of guardrail

Guardrails can be divided into three types according to the burying methods: column direct burying, flange connection and integral pouring, and they can be divided into PL 1, PL2 and PL3 according to the anti-collision grade. The guardrail is designed according to the design conditions provided by the anti-collision grade.
