Applications of Cold Rolled  C Channel:

The Cold Rolled  C Channel can be applied to construction of warehouses, workshops, sport stadiums and car parks etc.The hot rolled channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery.In details, the hot rolled channel steel is usually used for arch-itechtural structure, and they could be welded in order to support or hang a vari-ety of facilities. They are also usually used in combination with I beam. Generally,the hot rolled channel steel we supply must possess perfect welding property, riveting property and mechanical property and so on.


Package & Delivery of Cold Rolled  C Channel:

1.The channel steel will be packed in bundle with steel wire at each end of every bundle and color marking in order to help the customer to recognize his goods more easily at sight.

2. And the channel steel could be loaded into 20ft or 40ft container, or by bulk cargo.If the weight of each bundle reaches more than 3.5 mt, the loading by break bulk cargo should be choosed.When the weight of each bundle reaches less than 3mt, the loading by container should be choosed.

3.As for the transportaion from mill to loading port, the truck will be usually used. And the maximum quantity for each truck is 40mt.

4.All in all, we could do in accordance with customer's request.

Production Flow of Cold Rolled  C Channel:

1.The steel billet shall be heated in the high temperature furnace.

2. The heated steel billet shall be rolled five to nine times with the aim of shaping the general figure of steel u channel.

3. The rolled steel u channel should be put onto the cooling bed to make the temperature low.

4. The steel u channel should be straighted on the straightener.

5. The straighted steel u channel will be cut into meters by saw, as per customer's requirements.

6. At the last part of production, the channel steel must be tested in order to confirm that the finished products are completely free from crack, pore, slag, scab or fold on the surface.

Q:No. 20 b one meter with multiple channel
Each physical channel is the standard provisions of 20b# weight 25.777 kg, but the actual weight is not up to a difference.
Q:What's the difference between channel type 25a#, 25b# and 25c#?
Channel type 25a#, 25b#, 25c# is to indicate "waist height of the same" channel, but its leg width and waist thickness is different, so you need to add a, B, C to the right of the model to be distinguished. For example, 25a# means 250*78*7. 25b# stands for 250*80*9.
Q:14 of channel steel and 12 of I-beam which force?
14 of channel steel should be big.To help you check the manual, 14 of the channel mechanical parameters are greater than 12 of the I-beam, including the moment of inertia, the radius of inertia, cross section coefficients.Therefore, the same length of 14 channel steel can bear a greater force. (of course, in the same force.)However, the weight of channel steel 14 per metre is greater than that of 12 i-beam.
Q:Which kind of wind resistance is better for square tube, square tube or channel steel?
Why don't you buy square tubes directly? How do you budget?
Q:How to set the channel steel into a circle?
Is generally a narrow face half the diameter of the channel calculation, you can use this method to calculate the diameter + channel narrow surface, can calculate the total length of the 1030+43=1073, you can press the layout can be. Can experiment first, the length of the extension of several tens of millimeters, so as to avoid errors, according to the actual error can be processed, I do not know if I understand, there is a little more, ha ha
Q:Is channel steel cold rolled or hot rolled?
Belong to hot rollingThe raw material steel billet for channel steel is carbon or low alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered by hot forming, normalizing or hot rolling. The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means waist height is 100 mm, leg width is 48 mm, waist thickness is 5.3 mm channel, or 10# channel steel. The same height of the channel, if there are several different leg width and waist thickness, also need to add a, B, C on the right side of the model to distinguish, such as 25#a, 25#b, 25#c and so on.
Q:What kind of steel products are there, such as channel steel, angle iron and so on?
Screw thread steelThe general length of thread steel is 9m and 12M, 9m long thread is mainly used for road construction, and 12m long thread is mainly used for bridge construction. The thread specification range is generally 6-50mm, and the state allows deviations. Thread steel according to the strength of HRB335, HRB400, HRB500, three models.
Q:Channel structure, angle steel, I-beam and so on, if not painted, the impact on life?
With the continuous improvement of the quality of engineering, steel structure steel, steel, steel and other sections shall be made and preserved in use, if not treated will have great influence on the service life of workpieces. From the point of view of comprehensive cost and effectiveness of anti-corrosion treatment, hot-dip galvanizing, which is called "Iron Guard", should be the first choice for corrosion protection. The paint can only be used as protective treatment of the short term, it is low cost, fast construction but every 1-2 years for a brush maintenance, time-consuming late high cost galvanizing treatment at a time can keep 30-50 years or even permanent, because this has a great relationship with it service environment, coastal and inland, heavy industry District and country are very different.
Q:What does channel 150*8 mean?
As for the 150*8, it is likely to be a custom tagging method within the factory, which can be viewed from the sourceIf you guess by the results, it should be refers to the waist thickness of 8mm, leg width of 150mm of a certain type of channel.
Q:How to anchor the channel?
On the basis of the embedded 20 thick steel plate, with high-strength bolts or chemical bolts fixed, and then use the stiffener to clamp the middle of the channel, and use high-strength bolts to connect.
