Description

Technical Field

[0001] The invention relates to the technical field of steel guardrails, and in particular to a steel guardrail with a reflective coating and a production process thereof. Background Art

[0002] Guardrails are usually made of steel, such as round steel pipes, square steel pipes or corrugated steel plates. They have good impact resistance, low cost, long life and higher safety. Steel guardrails are often used on the edge of bridges to prevent people or vehicles from falling from the edge of the bridge.

[0003] Existing steel guardrails are mostly installed on both sides of the bridge to provide protection for passing vehicles and pedestrians. Then one or more layers of reflective coating are coated on the surface of the steel guardrail to reflect the light of the vehicle to alert vehicles and pedestrians passing by the bridge at night.

[0004] However, since various garbage may be left behind when vehicles and pedestrians move on the bridge, and the existing steel guardrails have relatively single functions, the garbage remaining on the bridge may be washed into the river by rainwater when it rains, causing the river environment to be polluted by garbage. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a steel guardrail with a reflective coating and a production process thereof.

[0008] Preferably, a plurality of second circular holes are opened on one side of the perforated plate, and the plurality of second circular holes are arranged at equal distances.

[0009] The effect achieved by the above components is: by setting the second circular holes, water can be discharged through the interior of the plurality of second circular holes, thereby improving the fluidity of the water.

[0010] Preferably, a plurality of filter plates are fixedly connected to a bearing on one side away from the circular axis, and outer rings of the plurality of bearings are respectively fixedly connected to inner walls of the plurality of holes of the perforated plate.
