Cut Processed Product And Guardrail

Abstract: Provided are: a cut-processed product of a Zn-Al-Mg-based plated steel material comprising a base steel material and a Zn-Al-Mg-based plating layer coated on the surface of the base steel material, in which a cut edge surface of the cut-processed product is covered by the Zn-Al-Mg-based plating layer at a cut edge surface covering ratio of 50 to 99%, each of a non-plated surface of the base steel material and the Zn-Al-Mg-based plating layer around the non-plated surface is covered with a repairing coating film in the cut edge surface of the cut-processed product, the initial coating film resistance value in the repairing coating film is 10 to 1000 O/cm2, the coating film resistance value after the immersion of the cut-processed product in 5%-by-mass salt water for 3 hours is 5 to 50 O/cm2, and the thickness of the repairing coating film is 10 µm or more; and a guardrail in which the cut-processed product is used.
