Technical field [0001]The present invention relates to a plated steel. 　The present application, to 06 May 16, 2017, claiming priority based on Japanese Patent Application No. 2017-118795, filed in Japan, the contents of which are incorporated here. BACKGROUND [0002]Electrical equipment, building materials, and, as the beginning of the automobile, the article touches in the eyes of the people, generally design resistance is required. As a method of enhancing the design property, method or sticking the film or painted to the surface of the article is common. However, in recent years, in Europe and the United States of nature-oriented, application of materials that take advantage of the texture of the metal has increased. From the viewpoint of taking advantage of the texture of the metal, the paint and the resin coating so impair the texture of the metal, as a material for an article, stainless steel or aluminum material excellent in corrosion resistance it is left unpainted are used. Even with such a stainless steel or aluminum material, the design resistance is required. In general, stainless steel and aluminum material, or imparting an arcuate fine irregularities called vibration, or subjected to such embossing, such as fine lines like irregularities called hairline to grant or, designability by surface machining It is increased. In particular, the appearance imparted with hairline is frequently used is preferred. [0003] 　Brushed (HL finish), as one of a surface finish of stainless steel, JIS G4305: In 2012, is defined as "that finished by polishing as continuous polishing th stick with abrasive appropriate particle size" ing. [0004] 　However, stainless steel or aluminum material is an expensive material. Therefore, inexpensive materials to replace these stainless steel or aluminum material is desired. One such alternative materials, the hairline and applied to the plating steel, a steel material to form a resin layer thereon. [0005] 　As a technique for imparting an appropriate corrosion resistance steel, galvanized superior in sacrificial protection against steel, or a technique of applying zinc alloy plating has been widely used. Such galvanized or zinc alloy plating (hereinafter collectively and galvanized and zinc alloy plating, also referred to as "zinc-based plating".) Steel with enhanced design properties and hairline granted to have been proposed. 　For example, Patent Document 1, the surface of the plating layer is a perpendicular direction of the surface roughness Ra (arithmetic average roughness) is 0.1 ~ 1.0 .mu.m to hairline, Toru an adhesive layer having a light transmitting property technique for forming a film layer having a light have been proposed. Patent Document 2, the Zn-Al-Mg-based hot dip plated layer hairline direction and hairline direction perpendicular roughness parameter which is formed on the surface layer of the (Ra and PPI) a specific range, and, Zn-Al-Mg technique for forming a transparent resin film layer is proposed to the surface of the system hot-dip plating layer. Patent Document 3, to steel sheet to transfer the texture rolling Zn and Zn alloy plating, a technique for organic coatings such as surface roughness is within a predetermined range has been proposed. CITATION Patent Document [0006] Patent Document 1: Japanese Registered Utility Model No. 3192959 discloses Patent Document 2: Japanese Patent 2006-124824 JP Patent Document 3: Japanese Kohyo 2013-536901 JP Summary of the Invention Problems that the Invention is to Solve [0007] 　The technique for coating the organic resin to steel sheet hairline is granted as proposed in the above Patent Documents 1 to 3 can be implemented to improve the design property caused by hairline, and to express a certain corrosion resistance it can. However, due to the presence of the resin coating, there is a problem that metallic effect (metallic luster) will be Moi. [0008] 　Stainless steel, since the corrosion resistance of stainless steel itself with the oxide film present on the surface is good, coating or the like for improving corrosion resistance is not required. That is, the metal matrix itself since it can be used on the surface, a problem that the loss of metallic effect by the resin coating does not originally exist. When performing resin coating for stainless steel, it is an object to impart coloration and another texture. Therefore, in stainless steel, the loss of metallic effect as the present inventors have findings had a problem. Such a situation is the same for the aluminum material. [0009] 　The present invention has been made in view of the above problems. An object of the present invention have a hairline appearance while using inexpensive steel and excellent metallic effect is to provide a high design property plated steel. This excellent design highly plating steel, it is preferable that excellent corrosion resistance (long-term corrosion resistance). Means for Solving the Problems [0010] 　Although zinc-based plating is excellent in sacrificial protection property, fingerprint resistance, processability, and, in order to ensure corrosion resistance, it is not enough galvanized. Therefore, in the case of the zinc-plated steel substitute for stainless steel and aluminum materials, resin coating is essential. However, as described above, metallic feeling is lost by resin coating. 　The present inventors have found that in order to solve the above problem, the resin-coated plated steel, of intensive investigation. As a result, the degree of gloss measured in the hairline direction G60 (Gl) of 70 to 400, and, with respect to the degree of gloss measured in the hairline direction perpendicular G60 (Gc), 0.30 ≦ Gc / Gl ≦ 0.70 when a, can feel a sense of good metallic, it has become known that the metallic effect is Moi If out of this range. That is, the present inventors have found that a person "has a hairline appearance, and, excellent metallic feeling" a sense of feel, and succeeded in for the first time quantified. Gloss G60 (Gl) is preferably 85 greater, and more preferably 100 or more. [0011] 　The present inventors have further studied in detail the phenomenon as described above. As a result, the reason why the person feels metallic effect as described above is lost is the impression of a metal matrix which is visible through the resin textures, the difference between the impression of the light reflected by the resin surface is because increases heading was. Specifically, since even the light in a resin surface from the difference in refractive index between the air be a transparent resin is reflected, and the impression of the metal matrix visible through the resin texture, of the light reflected by the surface of the resin the difference occurs in the impression. If this difference is large, it recognized the presence of the resin is strong, believed metallic appearance is Moi smaller impression of the metal matrix texture. [0012] 　The present inventors have based on the above findings, in addition to the shape of the plated surface, by controlling the shape of the resin surface within a certain range, and the impression of light reflected by the impression and the resin surface of the metal matrix texture suppressing the difference in the gloss conceived can be controlled within a predetermined range, and completed the present invention. 　Summary of the completed invention based on this finding is as follows. [0013] [1] plating steel material according to one embodiment of the present invention, a steel material and a zinc-based electroplated layer formed on the surface of the steel material, the organic resin coating layer formed on the surface of the zinc-based electroplated layer, wherein the surface of the zinc-based electroplated layer has a hairline that extends in a predetermined direction, in the surface of the zinc-based electroplated layer, the surface roughness Ra measured in the extending direction of the hairline (ML) is a 0.10 ~ 0.70 .mu.m, in the surface of the zinc-based electroplated layer, the peak number of PPI reference level 10μinch measured in a direction perpendicular to the stretching direction, the stretching direction direction with respect to the surface roughness measured in a direction perpendicular Ra (MC), satisfies the relationship represented by the following formula (I), the surface of the organic resin coating layer, which is perpendicular to the drawing direction relative to The measured surface roughness Ra (CC) is, the relative stretching direction to the measured surface roughness Ra (CL), satisfies the relationship represented by the following formula (II), the surface roughness Ra (CC ) is, with respect to the surface roughness Ra (MC), satisfies the relationship represented by the following formula (III). 　　≧ 350 × PPI Ra (MC) · · · · · · 　　(I) Ra (CC) / Ra (CL) ≧ 1.10 · · · · · · 　　(II) Ra (CC) 　As the base material of the plating steel according to the present embodiment, the present invention is not particularly limited, mechanical strength required for the plating steel (e.g., tensile strength, etc.) in response to such, various known steel it is possible to appropriately utilized. [0019] 　On the surface of the steel material as described above, and an organic resin coating layer and the zinc-based electroplated layer is formed on the surface of the zinc-based electroplated layer, in a predetermined direction along hairline and is formed. [0020] [For type and composition of the zinc-based electroplated layer] 　zinc-based electroplated layer of plating steel according to this embodiment, electro-galvanized or electro zinc alloy plating (hereinafter, collectively referred to as "zinc-based electroplating." ) is formed by. [0021] 　Respect plated metal, the plating other than zinc plating, since inferior sacrificing corrosion resistance, cut edge when use is not suitable for applications which are exposed unavoidably. 　Since the zinc concentration of the zinc-based plating layer too low sacrificial protection ability decreases, zinc alloy plating, based on the total weight of the plating film, it is preferable to contain zinc than 65 mass%. [0022] 　Further, as the plating method of the zinc-based plating, in addition to the electroplating, there are such hot dipping or spraying method or a vapor deposition plating method. However, the hot-dip plating method, the inevitably dross mixed in solidified patterns and plating layer such as spangle, since inferior quality of appearance, is unsuitable. Further, in the spraying method, can not ensure the uniformity of the appearance by a gap inside the plated film is unsuitable. In addition, the vapor deposition method, because the poor in film-forming speed is slow productivity, it is not suitable. Therefore, the plating steel according to the present embodiment, in order to perform the zinc-based plated steel material surface, utilizes electroplating. [0023] 　Electrolytic zinc alloy plating according to the present embodiment, Co, Cr, Cu, Fe, Ni, P, Sn, Mn, Mo, V, W, and any one or more elements selected from the element group consisting of Zr , and a Zn and impurities. Further, electrolytic zinc plating containing Zn and impurities. Here, the impurities, not that with intentionally added as a zinc-based electroplated components, or mixed in the raw material, or is intended to be mixed in the manufacturing process, Al, Mg, Si, Ti, B it can include S, N, C, Nb, Pb, Cd, Ca, Pb, Y, La, Ce, Sr, Sb, O, F, Cl, Zr, Ag, W, and the like. In the case of electro-galvanized, depending on the breed of electroplating steel produced in the same manufacturing facility, Co, Cr, Cu, Fe, Ni, P, Sn, Mn, Mo, V, W, Zr, there is a case where Pb or the like as impurities. In the present embodiment, impurities, be present below about 1.0 wt% in total based on the mass of the total plating, effects obtained by plating is not impaired. [0024] 　In zinc-based electroplated layer of the present embodiment, sacrificial protection ability decreases when the Zn content is excessively reduced. Therefore, Zn content, relative to the total weight of the plating film is preferably 65% ​​or more as described above, more preferably 70% or more, particularly preferably 80% or more. [0025] 　The composition of the zinc-based electroplated layer as described above, can be analyzed, for example, by the following method. That is, the solvent or remover does not attack the plating layer (e.g., Neoriba S-701: San Cai Chemical Co., Ltd.) after the removal of the organic resin coating layer with a release agent such as a zinc-based electroplated layer such inhibitors containing hydrochloric acid It was dissolved, ICP: can be analyzed by (inductively coupled plasma) emission spectrometer. [0026] [For the surface shape of the zinc-based electroplated layer] 　surface of the zinc-based electroplated layer according to the present embodiment includes a hairline. The surface of the zinc-based electroplated layer, the surface roughness Ra measured in the hairline direction (ML) is 0.10 ~ 0.70 .mu.m. It is preferable hairline perpendicular measurement direction the surface roughness Ra (MC) is less than 1.00 .mu.m. 　Further, the surface of the zinc-based electroplated layer were measured in the hairline orthogonal direction, the number of peaks PPI (Peaks Per Inch) to a reference level was 10μinch is, the surface roughness Ra (MC) as measured in the hairline direction orthogonal unit: against [mu] m], satisfies the relationship represented by the following formula (I). [0027] 　　ＰＰＩ≧３５０×Ｒａ（ＭＣ）　・・・・・・（Ｉ） [0028] 　Here, Ra is the arithmetic mean roughness defined in JIS B 0601, PPI was defined in SAEJ911-1986, from the average line of the extracted curve, 1inch (inches) per obtained by counting the reference level as a threshold value is the number of mountain (peak number). Further, as mentioned above, Ra (ML) was measured hairline direction parallel a Ra of the surface of the zinc-based electroplated layer, Ra (MC) zinc-based electroplated, measured in a direction perpendicular to the hairline a Ra of the surface of the plating layer. [0029] 　If Ra of (ML) is more than 0.70 .mu.m, zinc and scattering of light becomes too large at the surface of the electroplated layer, the glossiness measured in the hairline direction after lacquered G60 (Gl) is less than 70, lose a sense of metallic. Therefore, in the present embodiment, the upper limit of Ra (ML), was 0.70 .mu.m. On the other hand, to grant hairline to the extent that visible, it is necessary to 0.10μm or more roughness in hairline direction. Therefore, in the present embodiment, the lower limit of Ra (ML), was 0.10 .mu.m. In the present embodiment, a more preferable range of the Ra (ML) is 0.10 .mu.m ~ 0.50 .mu.m. [0030] 　When Ra (MC) exceeds 1.00 .mu.m, in particular (a direction parallel to the rolling direction, a direction to impart a hairline) L direction of the steel sheet Ra is large, and when the plating layer is thin, exposed matrix the possibility to become undesirably high. More specifically, Ra according steel plate than 1.00 .mu.m, and, if the plating thickness is 5.5μm or less, because the possibility of matrix is ​​exposed is increased undesirably. [0031] 　Was measured in the hairline orthogonal directions, PPI of the reference level was 10μinch is, if not met for Ra (MC) of formula (I), the density of the hairline becomes too small. In this case, 0.30 no longer satisfies the relationship of ≦ Gc / Gl ≦ 0.70, as a result, metallic appearance is lowered, it becomes poor design. PPI to the reference level was 10μinch measured in hairline orthogonal direction, more preferably, satisfy the relationship expressed by the following (I) 'equation. [0032] 　　ＰＰＩ≧４５０×Ｒａ（ＭＣ）　・・・・・・（Ｉ）’ [0033] 　Each Ra is to measure any 10 places on the surface of the zinc-based electroplated layer in a predetermined direction (hairline direction or hairline perpendicular direction), the up-side two points and the minimum side two locations and excluding the six locations Ra which is the average value. 　And a surface roughness Ra in each direction, PPI of the reference level was 10μinch can be measured with roughness meter of all stylus type. After forming the later-described organic resin coating layer, when measuring the surface roughness of the zinc-based electroplated layer after removing the organic resin coating layer with a release agent such as a solvent or remover does not attack the plating, measuring the may be performed. Upon measurement, measuring the length of the PPI 1inch, evaluation length of Ra may be five times the reference length (cutoff wavelength), measurement speed may be a 0.5 mm / sec. [0034] [Base steel for exposure ratio] 　base steel exposure ratio of the zinc-based electroplated layer according to the present embodiment is preferably less than 5%. In the present embodiment, the corrosion resistance is sufficiently ensured by galvanized or zinc alloy plating. However, if the base steel is exposed during hairline grant, more long-term corrosion resistance to the influence of galvanic corrosion (long corrosion resistance) may be lowered. Such long corrosion resistance degradation is often a prominent in base iron exposure rate of 5% or more. Therefore, the base steel exposure ratio is preferably less than 5%. 　In the present embodiment, by base iron exposure ratio of the zinc-based electroplated layer is less than 5%, generally in addition to the moderate corrosion resistance required for the steel material, such as excellent long-term corrosion resistance, have very good corrosion resistance the things. The base iron exposure ratio of the zinc-based electroplated layer is more preferably 3% or less, and more preferably 0%. 　Base steel exposure ratio is plated with a release agent such as a solvent or remover after removing the organic resin coating layer is not affected, any 1mm square five places to EPMA analysis, the area ratio Zn is not detected for the analysis area image by analyzing, it can be obtained. In the present embodiment, it is determined that 1/16 or less and a region of Zn is not detected area when the detected intensity of Zn was measured standard sample (pure Zn). [0035] [Zinc for coating weight of electroplated layer] 　coating weight of the zinc-based electroplated layer according to the present embodiment, 10 g / m 2 is preferably at least. From the viewpoint of corrosion resistance, if ensure desired corrosion resistance, but not ask the adhesion amount of the zinc-based electroplated layer, the adhesion amount of the zinc-based electroplated layer is 10 g / m 2 of less than, the earth upon hairline grant iron exposure rate is likely to exceed 5%. Adhesion amount of the zinc-based electroplated layer is more preferably 15 g / m 2 or more, more preferably 20 g / m 2 is at least. The upper limit of the coating weight of the zinc-based electroplated layer, in view of the manufacturing cost and the like of the plating steel according to the present embodiment may be appropriately determined, for example, 40 g / m 2 may be about. Upper limit of the coating weight is preferably, 35 g / m 2 is. [0036] 　Although the zinc-based electroplated layer comprising plating steel according to the present embodiment has been described in detail. 　Subsequently, in the plating steel according to the present embodiment, an organic resin coating layer formed on explaining (the side opposite to the steel) surface of the zinc-based electroplated layer. [0037] 　surface of the zinc-based electroplated layer hairline has been applied as described above, (in other words, the organic resin having a light-transmitting property) transparent organic resin is coated with. "Organic resin having translucency", when formed on the surface of the plating layer, the plating layer through the organic resin coating layer is meant that can be observed visually. [0038] [For the components of the organic resin coating layer] 　resin used for forming the organic resin coating layer is not limited in particular as long as it retains sufficient translucency. For example, epoxy resins, urethane resins, polyester resins, phenolic resins, polyether sulfone-based resin, melamine-alkyd resins, acrylic resins, polyamide resins, polyimide resins, silicone resins, polyvinyl acetate resins, polyolefin resins, polystyrene resins, vinyl chloride resins, vinyl acetate resins are available. [0039] 　The metal (i.e., zinc-based electroplated layer located below the organic resin coating layer) in order to improve the adhesion between for the various resins, may be introduced, such as silanol groups. In the formation of the organic resin coating layer may be used alone above various resins may be used mixtures of these resins. Further, the organic resin coating layer may be a single-layer structure of the various resins may be a laminated structure of the various resins. [0040] 　Furthermore, as a means for improving the adhesion between the organic resin coating layer and the zinc-based electroplated layer, within a range not to impair the appearance, against plated steel consisting of the steel material and the zinc-based electroplated layer, the inorganic process Ya the organic-inorganic composite treatment and surface modification treatment or the like may be subjected to. Here, "disfigurement", or reduce the transparency, or cause uneven gloss, such as or cause abnormal irregularities sense, means to reduce the feeling of metallic. As such a process, for example, a Zr oxide treatment, or Zn oxide treatment, silane coupling agent treatment or mild acid immersion treatment and include weak alkali immersion treatment. [0041] 　In order to add the desired performance to the organic resin coating layer, the range not impairing the transparency and appearance and, without departing from the scope defined in the present invention may contain various additives. The performance to be added to the organic resin coating layer, for example, corrosion resistance, sliding properties, 耐疵 with, conductivity, color tone and the like. For example, if the corrosion resistance, may be contained, such as rust inhibitors or inhibitors, if the sliding property and 耐疵 with resistance, may be contained and waxes and beads, if conductive, conductive agent it may be contained and, if tone, may be incorporated such as a pigment or dye. [0042] [For the surface shape of the organic resin coating layer] 　The organic resin coating layer according to the present embodiment, due to the hairline formed on the surface of the zinc-based electroplated layer is lower, the surface shape as described in detail below having. [0043] 　That is, the surface of the organic resin coating layer according to the present embodiment, when attention is focused on the hair line direction and hairline perpendicular direction in the zinc-based electroplated layer, the surface was measured hairline direction perpendicular roughness Ra (CC) [Unit: [mu] m ] is, the surface roughness Ra measured in the hairline direction (CL) [unit: against [mu] m], satisfies the relationship represented by the following formula (II), and zinc-based electricity measured hairline orthogonal direction against a surface roughness Ra of the surface of the plating layer surface roughness Ra (MC), satisfies the relationship represented by the following formula (III).
