Guardrail Post Function
Support and Fixation
- Provide structural support: The guardrail post is the supporting foundation of the entire guardrail structure.
- Fix the guardrail position: One of the main functions of the guardrail post is to fix the guardrail so that the guardrail plate can be kept in the correct position and height.
Guidance and Buffering
- Guide traffic: The guardrail post can provide clear road boundaries, guide vehicle traffic, and improve traffic safety.
- Energy absorption and buffering: When hit by a vehicle, the guardrail post can absorb and disperse the collision energy, reducing the impact on the vehicle and the driver and passengers.
Safety protection
- Prevent vehicles from running off the road: The guardrail post and the corrugated guardrail and other components form a safety barrier to effectively prevent vehicles from running off the road.
- Warning function: Some guardrail posts may be equipped with reflective signs or warning signs to remind pedestrians and vehicles to pay attention to safety.
Guardrail Post Weight Calculation
Round Guardrail Post Weight Calculation
- W=(D – t) x t x L x 0.02466
- W represents the weight of the post in kg.
- D represents the outer diameter of the post in mm.
- t represents the wall thickness of the post in mm.
- L represents the length of the post in m.
- 0.02466 is the value obtained by π x 7.85.
For example, a circular guardrail post with a diameter of 140mm, a wall thickness of 4mm, and a length of 1.2m has a weight of W=(140 – 4) x 4 x 1.2 x 0.02466≈16.1kg
Square Guardrail Post Weight Calculation
- W = 4x (a – t) x t x L x ρ
- W represents the weight of the post in kg.
- a represents the side length of the square post in m.
- t represents the wall thickness of the post in m.
- L represents the length of the post in m.
- ρ represents the density of steel, which is 7850kg/m³
For example, a square guardrail column with a side length of 0.13m, a wall thickness of 0.006mm, and a length of 1.5 meters has a weight of W=4x (0.13-0.006) x 0.006 x 1.5 x 7850≈35.2kg
