规格:螺纹钢的规格要求应列在进出口贸易合同中。一般应包括标准等级(类型代号)、钢筋公称直径、公称重量(质量)、规定长度和上述指标的允许差异。推荐标准直径为6, 8, 10,12, 16, 20,25, 32, 40和50毫米钢筋系列。1供应长度分为标尺和倍性两种。对中国的出口螺纹钢固定长度的选择范围是6 ~ 12m,与日本螺纹钢固定长度的选择范围是3.5 ~ 10m,与国内销钢通常具有9、12月的长度,如果它不在合同规定。

外观质量:表面质量。螺纹钢的表面质量按有关标准规定,端面应平直,表面不应有裂纹、疤痕和折叠,使用中不应有有害缺陷。形状和尺寸偏差允许值。螺纹钢的弯曲和增强几何要求在相关标准中有规定。我国标准规定,直杆的弯曲度不影响正常使用,总弯曲度不大于钢筋总长度的0.4%。

Specifications: the specification requirements for rebar should be listed in the import and export trade contract. Generally, it should include the standard grades (type code), the nominal diameter of the steel bar, the nominal weight (quality), the specified length and the allowable difference of the above indexes. The recommended standard diameter is 6, 8, 10, 12, 16, 20, 25, 32, 40 and 50mm of rebar series. The [1] supply length is divided into two kinds of ruler and ploidy. The selection range of the fixed length of China's export screw steel is 6 ~ 12M, and the selection range of the fixed length of the Japanese whorled steel is 3.5 ~ 10m, and the domestic domestic pin steel usually has two lengths of 9m and 12M, if it is not specified in the contract.


Appearance quality: surface quality. The surface quality of the screw steel is stipulated in the relevant standards, and the end should be cut straight, the surface should not have cracks, scars and folding, and the harmful defects in the use should not exist. Allowable value for deviation of shape and size. Requirements for bending and reinforcement geometry of threaded steel are specified in relevant standards. If the standard of our country stipulates, the bending degree of straight bar shall not affect normal use, the total bending degree is not greater than 0.4% of the total length of reinforcing steel bar.


No cracks, scarring and folding shall be allowed on the surface of steel bars. The surface of the steel bar is allowed to have a convex block, but it must not exceed the height of the transverse rib. The depth and height of the other defects on the surface of the steel bar must not be greater than the allowable deviation of the size of the location.
