波形鋼板:波形鋼板應(yīng)采用熱鍍鋅處理,確保其耐腐蝕性能。波形形狀應(yīng)符合標(biāo)準(zhǔn),波峰和波谷的尺寸應(yīng)符合規(guī)定。同時,波形鋼板的表面應(yīng)平整,無明顯凹凸和劃痕。

Waveform steel plate: Waveform steel plate should be hot-dip galvanized to ensure its corrosion resistance. The waveform shape should meet the standards, and the size of the peaks and valleys should meet the regulations. Meanwhile, the surface of the corrugated steel plate should be flat, without obvious bumps or scratches.

立柱:立柱應(yīng)采用熱鍍鋅處理,確保其耐腐蝕性能。立柱的直徑和壁厚應(yīng)符合規(guī)定,表面應(yīng)平整光滑,無明顯凹凸和劃痕。立柱的安裝間距應(yīng)符合設(shè)計要求,確保整個護(hù)欄的穩(wěn)固性。

Column: The column should be hot-dip galvanized to ensure its corrosion resistance. The diameter and wall thickness of the column should comply with regulations, and the surface should be flat and smooth without obvious bumps or scratches. The installation spacing of columns should meet the design requirements to ensure the stability of the entire guardrail.
