Specifications: Suitable for ∅114 columns; suitable for ∅140 columns.
Materials: Q235 high-quality low-carbon steel; rubber.
Surface treatment: The wave beam steel guardrail column cap made of Q235 high-quality low-carbon steel material is generally treated with hot-dip galvanizing and hot-dip galvanizing + powder coating processes for surface corrosion protection. The color of the hot-dip galvanizing process is the natural color of metallic zinc; the color for hot-dip galvanizing + powder coating process is usually mint green (RAL: 6029), traffic white (RAL: 9016), light green (RAL: 6027), sky blue (RAL: 5015), light orange yellow (RAL: 1028).
