Now highway, highway is has been widely used for roadway railings , the current times have by highway guardrail plate completely replaced the concrete reinforced wall partition of times, phase
For the safety of the people is to the corresponding improved a lot. Below we liaocheng HengXin company as the most professional guardrail plate manufacturers came for you "is" out why highway guardrail plate is the most close.
The angel of fitness.
When
roadway railings in a critical forces under the action of Fs occurred plastic deformation, the yield strength for Fs/As, among them As are beginning to happen when the plastic deformation of the cross-sectional area of the
fence. When the force continued to increase up to a limit value Fe, guardrail will fracture; Guardrail by the stress at fracture is called tensile strength, and promising Fb/Ab, including Ab is guardrail fracture of sectional area.
Therefore, roadway railings plastic energy dissipation rate e equal to guardrail deformation under when the average deformation stress and its largest plastic elongation of the product. Thus it can be seen, improve the strength of the barrier or
Elongation can increase its plastic energy consumption rate and improve the security of highway guardrail plate.
