1、化學性能:鐵藝護欄耐化學腐蝕和電化學腐蝕性能在鋼材中非常好，僅次于鈦合金。

1. Chemical properties: Iron guardrails have excellent resistance to chemical and electrochemical corrosion compared to steel, second only to titanium alloys.

2、物理性能：耐熱、耐高溫、耐低溫甚至耐超低溫。

2. Physical properties: Heat resistance, high temperature resistance, low temperature resistance, and even ultra-low temperature resistance.

3、機械性能：根據不同類型的鐵藝術，機械性能不同，馬氏體鐵藝術具有高強度和硬度。奧氏體鐵藝術塑性好，強度不太高，但耐腐蝕性在鐵藝術中很好。鐵素體鐵藝術機械性能適中，強度不太高，但耐氧化。

3. Mechanical properties: Depending on the type of iron art, the mechanical properties vary, and martensitic iron art has high strength and hardness. Austenitic iron has good plasticity and low strength, but its corrosion resistance is very good in iron art. Ferrite iron has moderate mechanical properties, moderate strength, but is resistant to oxidation.

4、工藝性能:奧氏體鐵藝工藝性能好，塑性好，適合壓力加工。由于硬度高，馬氏體鐵藝工藝性能差。

4. Process performance: Austenitic iron has good process performance, good plasticity, and is suitable for pressure processing. Due to its high hardness, martensitic iron has poor processability.

鋁合金護欄特點：

Characteristics of aluminum alloy guardrail:

1、鋁合金護欄不需要油漆和維護，長新不舊，避免了維護的疲勞和麻煩，綜合成本低。

1. Aluminum alloy guardrails do not require painting or maintenance, they are new and never old, avoiding maintenance fatigue and trouble, and have low overall costs.

2、生產安裝簡單快捷，采用zhuanli插扣式連接，大大提高了安裝效率。
