C型钢是房屋建筑中常见的一种，也就是说，这种钢材作为建筑材料具有优点，它不仅具有的性，而且具有较不错的稳定性。在相同的应用情况下，与以前使用的铝合金相比，C型钢不仅具有形状特、用量少的优点，而且具有良好的绿色性。

C-shaped steel is a common kind of building materials. In other words, this kind of steel has advantages as a building material. It not only has the property of, but also has good stability. In the same application, compared with the aluminum alloy used before, C-beam not only has the advantages of special shape and less consumption, but also has good green property.

C型钢是用热卷板冷弯成型，壁薄，重量轻，截面性能优良，强度不错。与守旧槽钢相比，同等强度可节省30个点的材料。C型钢具有尺寸可调、抗压的优点。

C-shaped steel is formed by cold bending with hot-rolled plate, with thin wall, light weight, excellent section performance and good strength. Compared with the old-fashioned channel steel, the same strength can save 30 points of material. C-shaped steel has the advantages of adjustable size and compression resistance.

C型钢，表面光滑，锌层均匀，附着力强，尺寸精度不错，所有表面都包裹有锌层，表面锌含量通常为120-275克/㎡。它使用寿命不错、蚀、经久经用，是一种防护性好、质量高的镀锌产品。

C-shaped steel has smooth surface, uniform zinc layer, strong adhesion and good dimensional accuracy. All surfaces are wrapped with zinc layer, and the surface zinc content is usually 120-275 g / ㎡. It has good service life, corrosion and durability. It is a kind of galvanized product with good protection and high quality.

一、C型钢纵向弯曲：C型钢向上弯曲时，一排矫直轴向下压，向下弯曲时，排矫直轴向上推。

1、 Longitudinal bending of C-shaped steel: when C-shaped steel is bent upward, a row of straightening shafts are pressed downward, and when it is bent downward, the row of straightening shafts are pushed upward.

二、C型钢小侧边跑偏：通过进料端调整夹送辊。如果左侧小边大，左侧夹送辊会松，右侧夹送辊会紧。

2、 C-shaped steel small side deviation: adjust the pinch roll through the feeding end. If the left small side is large, the left pinch roll will be loose and the right pinch roll will be tight.

三、C型钢横向弯曲：当C型钢向左端弯曲时，松开排出料端的左夹送辊，调整右夹送辊。

3、 Horizontal bending of C-shaped steel: when C-shaped steel bends to the left, loosen the left pinch roll at the discharge end and adjust the right pinch roll.

C型钢的处理步骤如下：

The treatment steps of C-shaped steel are as follows:

一、材料选择。16M或20M16X80钢板；

1、 Material selection. 16m or 20m16x80 steel plate;

二、热轧。钢板加热到1000-1200摄氏度进行热轧。

2、 Hot rolling. The steel plate is heated to 1000-1200 ℃ for hot rolling.

三、打孔和攻丝。在电缆的三个侧面打一个22.5毫米的孔，然后用M24*35螺栓攻丝制作M24螺纹扣。

3、 Punching and tapping. Drill a 22.5MM hole on the three sides of the cable, and then use m24*35 bolt tapping to make M24 thread buckle.

四、切割。25U电缆材料长460mm，29U电缆材料长480mm。

4、 Cutting. 25U cable material is 460mm long, and 29U cable material is 480mm long.

在存放C型钢时，要注意以下几点：

When storing C-shaped steel, pay attention to the following points:

一、C型钢堆放的原则是堆放平稳，堆放高度不宜过高，以免造成型钢滑动的危险。

1、 The principle of stacking C-shaped steel is to stack it stably, and the stacking height should not be too high, so as to avoid the danger of forming steel sliding.

二、存放C型钢的仓库需要清洁、干燥、通风。

2、 The warehouse storing C-shaped steel needs to be clean, dry and ventilated.

三、酸、碱、盐、水泥等腐蚀性材料不能入库。

3、 Corrosive materials such as acid, alkali, salt and cement cannot be warehoused.

四、露天堆放的C型钢应垫木垫或木条，堆放面应稍倾斜，以利排水。

4、 C-shaped steel stacked in the open air shall be padded with wood mats or strips, and the stacking surface shall be slightly inclined to facilitate drainage.

五、济南C型钢厂认为不同类型的C型钢需要分开堆放，以便于搬运、放置和管理。C型钢和其他钢材一样，经常用于建筑工程中，在使用前要经过加工。

5、 Jinan C-section steel plant believes that different types of C-section steel need to be stacked separately to facilitate handling, placement and management. C-shaped steel, like other steels, is often used in construction projects and must be processed before use.
