How about the performance of highway guardrail to absorb vehicle impact?

The guardrail plate is semi-steel, when a group of a group of guardrail plate connected, and supported by the column. When receiving a strong impact from the outside world, it forces the ground, the column, the block and the corrugated guardrail plate to deform to absorb energy, and the deformation of each component can absorb strong energy. Semi-steel guardrail plate buffer capacity is greater, better absorption capacity, no matter how large the impact will not break.
