摘要: A flat steel wire has a rectangular shape with rounded corners when a cross section perpendicular to a longitudinal direction is viewed. In the flat steel wire: a short side of the cross section is 2 mm to 7 mm; a long side of the cross section is longer than 8 mm to 56 mm; a ratio of the long side to the short side is more than 4 to 8; a tensile strength is 1900 MPa or more; and a twisting value is 12 times or more.

摘要: A resin-coated high-tension flat steel wire includes a high-tension flat steel wire and a fiber-reinforced polyamide resin coated layer. A shape of the high-tension flat steel wire when viewed from a section perpendicular to a longitudinal direction thereof is a rectangular shape including curved portions at four comers thereof. When, among four straight lines that form the rectangular section, the ranges from both end points of the straight lines that form long sides to one fourth of the length of the straight lines are respectively defined as one-fourth segments, a shape of the fiber-reinforced polyamide resin coated layer in the rectangular section includes a mountain shape having an apex within each of the one-fourth segments, and includes a minimum point, where the thickness of the fiber-reinforced polyamide resin coated layer is the minimum, between the apex and both the ends within each of the one-fourth segments.
