橋梁隔離防撞欄 茂名不銹鋼復合管燈光護欄

Bridge isolation anti-collision barrier Maoming stainless steel composite tube light barrier

例如：橋梁結構物一般都位于地面以上很高處。

For example: bridge structures are generally located very high above the ground.

過大的變形容易導致護欄承受出現除車輛碰撞力以外的其他荷載類型。

Excessive deformation will easily lead to other load types except vehicle collision force.

使受力變得更為復雜。

Make the force more complicated.

而鋼護欄一般較砼護欄柔一些，若需要兩者受碰撞后的變形一致。

The steel guardrail is generally more flexible than the concrete guardrail, and the deformation of the two guardrails after collision is consistent if necessary.

則鋼護欄需要更大的剛度，對鋼護欄材料也相應較高。

Therefore, the steel guardrail needs more stiffness, and the material of steel guardrail is also relatively high.
