C型钢的外观质量检验

Appearance quality inspection of C-shaped steel

一、肉眼观察冷拉C型钢表面时，表面应洁净、光滑、光亮或无光泽，无裂纹、夹杂物、发际线、褶皱和鳞片。个别小划痕、拉伸裂纹、黑点、四边、麻点等。允许不大于实际尺寸的公称尺寸偏差。

1、 When observing the surface of cold-drawn C-shaped steel with the naked eye, the surface should be clean, smooth, bright or dull, without cracks, inclusions, hairlines, wrinkles, and scales. Individual small scratches, tensile cracks, black spots, four edges, pits, etc. Allow nominal size deviation not greater than the actual size.

佰富彩二、型钢应平直，钢板应平整，侧端应切割成直角。除上述规定外，轨端和螺栓孔表面不可以有缩孔、脱层和裂纹，两端应铣平。

佰富彩2、 The section steel should be straight, the steel plate should be flat, and the side ends should be cut into right angles. In addition to the above regulations, there should be no shrinkage, delamination, or cracks on the surface of the rail end and bolt hole, and both ends should be milled flat.

三、用肉眼观察热轧C型钢表面时，不应有裂纹、褶皱、结疤、分层和夹杂物。允许有凹痕、局部凸起、四边和凹坑，但高度或深层不可以超过相关技术标准。允许去掉局部缺陷，但不允许横向去掉。移除不可以超过该尺寸与实际尺寸之间的C型钢允许负偏差。

3、 When observing the surface of hot-rolled C-shaped steel with the naked eye, there should be no cracks, wrinkles, scars, layering, or inclusions. Dents, local protrusions, edges, and pits are allowed, but the height or depth cannot exceed relevant technical standards. Local defects are allowed to be removed, but horizontal removal is not allowed. Remove the allowable negative deviation of C-shaped steel that cannot exceed the difference between this size and the actual size.

四、钢管的壁厚、表面粗糙度、圆度和直线度应符合技术标准。螺纹管、镀锌钢管和地质管的连接螺纹应涂油，并配有保护环。

佰富彩4、 The wall thickness, surface roughness, roundness, and straightness of steel pipes should comply with technical standards. The connecting threads of threaded pipes, galvanized steel pipes, and geological pipes should be coated with oil and equipped with protective rings.

佰富彩五、镀锌钢板和镀锌钢管的镀锌层不允许有裂纹、分层、漏镀等缺陷。

5、 The galvanized layer of galvanized steel plates and galvanized steel pipes shall not have defects such as cracks, layering, or missed plating.

六、型钢外观应平整、整齐，其圆度、边宽、高度、厚度、长度、扭转、斜度、波浪曲率、波浪弯曲度、平直度不可以超过相关标准规定的偏差。

6、 The appearance of the section steel should be flat and neat, and its roundness, edge width, height, thickness, length, torsion, slope, wave curvature, wave bending, and straightness should not exceed the deviation specified in relevant standards.

济南c型钢的堆放

佰富彩Stacking of Jinan C-beam

一、堆放原则是在稳定堆放、确定的情况下，按品种、规格堆放。不同品种的材料应分开堆放，防止混淆和相互腐蚀。

1、 The stacking principle is to stack according to variety and specifications under stable and determined conditions. Different types of materials should be stacked separately to prevent confusion and mutual corrosion.

佰富彩二、同样的材料按照仓单分开堆放，便于先出原则的实施。

佰富彩2、 The same materials are stacked separately according to the warehouse receipts, which facilitates the implementation of the first out principle.

三、垛间应有相应的通道，检查通道一般为0.5m，进出通道一般为1.5~2.0m，具体视材料和运输机械的大小而定。

3、 There should be corresponding passages between the stacks, with an inspection passage generally of 0.5m and an entry and exit passage generally of 1.5-2.0m, depending on the size of the materials and transportation machinery.

四、禁止在堆放位置附近存放腐蚀性为C型钢的物品。

4、 It is prohibited to store items with corrosive C-shaped steel near the stacking location.

佰富彩五、桩底应高、实、平，防止材料受潮或变形。

5、 The pile bottom should be high, solid, and flat to prevent moisture or deformation of the material.

出厂前使用C型钢防腐剂或其他电镀和包装是防止材料腐蚀的重要措施，在运输、装卸过程中应加以保护，不可以损坏，并能延长材料的储存寿命。更多相关事项就来我们网站http://0082tv.com咨询！

佰富彩The use of C-shaped steel anti-corrosion agents or other electroplating and packaging before leaving the factory is an important measure to prevent material corrosion. It should be protected during transportation, loading and unloading, not damaged, and can extend the storage life of the material.
