Cut-and-processed product, and guardrail

Abstract

A cut-and-processed product of a Zn—Al—Mg-based plated steel material including a base steel material and a Zn—Al—Mg-based plating layer covering a surface of the base steel material, in which a cut end surface of the cut-and-processed product is covered with a linear film in which a component of the Zn—Al—Mg-based plating layer linearly flows, and a coverage of the cut end surface with the linear film is from 60 to 90%, a non-plated surface of the base steel material and the linear film around the non-plated surface, in the cut end surface of the cut-and-processed product, are covered with a repair coat, an initial coat resistivity is from 10 to 1000 Ω/cm2 and a coat resistivity after immersion of the cut-and-processed product in 5% by mass salt water for 3 hours is from 5 to 50 Ω/cm2, in the repair coat, and a thickness of the repair coat is from 10 to 100 μm, as well as a guardrail utilizing the cut-and-processed product.
