ISO 5002:2013规定了切割长度或线圈形式的商用和拉伸质量的碳钢板的特性,电解沉积镀锌。电解镀锌板用于制造成型零件或其他零件,可进行化学处理,使其更适合涂漆。对于同等涂层、差异涂层或单面涂层板材,锌涂层以每面厚度的微米表示。这些板材通常带有涂层,如果不进行化学处理和涂漆,这些涂层不会承受户外暴露。
电解镀锌板的厚度可为0.36mm或更厚(通常可达4.0mm),宽度可为600mm或以上,并可制成线圈或切割长度。一般认为,厚度小于0.36 mm或大于4.0 mm的材料可适用于电解锌涂层,如有需要,可由相关方协商确定。
ISO 5002:2013 specifies the characteristics of carbon steel sheet of commercial and drawing qualities in cut length or coil form, zinc coated by electrolytic deposition. Electrolytic zinc-coated sheet is intended for the manufacture of formed or of miscellaneous parts, and can be supplied chemically treated to render it more suitable for painting. The zinc coating is expressed in micrometres of thickness per side, for equally coated, differentially coated, or one-side-coated sheets. These sheets are generally produced with coatings, which are not intended to withstand outdoor exposure without chemical treatment and painting. Electrolytic zinc-coated sheet can be produced in thicknesses of 0,36 mm and thicker (normally up to 4,0 mm) and in widths of 600 mm and over in coils or cut lengths. It is recognized that materials thinner than 0,36 mm or thicker than 4,0 mm can be suitable for electrolytic zinc coating, and, if required, be the subject of agreement between the interested parties.
