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.

 

 Cold Rolled  C Channel

 

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:6.3# how long is the channel length?
More than 6 meters, 9 meters in general, 12 meters of basic No. You said that the specifications of channel steel, many in the design, have to use steel plate to bend, or angle / rectangular tube replaced, the specifications are too small, are non-standard, can be replaced by a lot.
Q:Channel steel, I-steel, round bar, angle steel, Fang Gang price is per ton to count or by rice? How about tons and meters? The formula is best
Are generally by tons to calculate, according to tons of words directly or weigh the theoretical calculation, which is the theory that the weight per unit volume, volume density of X steel, the density of 7.85 tons per cubic meter.
Q:8 channel steel and 40*60 square steel tube, which is good in bending strength?
The channel steel should have good flexural strength
Q:What is the difference between channel steel or C steel?
Section C is produced by cold rolling of strip steel, which is generally supplied by steel structure and thinner in thickness. In addition, their cross-section is not the same, the channel is straight side, C steel is curling.
Q:What does channel specification "MQ-41" mean?
The raw material for producing 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:How to set the channel steel into a circle?
Divide the line 16 from 0.1.2.3 to 16. Calculate the two diameter elbow lofting: Yn=r cos alpha when 0 DEG n below 90 DEG Yn=1/2 alpha (d-2t alpha) cosWhen 90 degrees less than or equal to 180 degrees when n < alpha Yn=1/2dcos alphaIn the formula, the Yn--- expansion graph has a circumferential length equal to the curve coordinate value;R--- auxiliary circle radius;D--- diameter of round tube;T--- plate thickness;Alpha n--- auxiliary circumferential equal angle; tube of 300mm diameter,N optional 16 alpha 1=360 degrees, /16=22.5 degrees, 2=45 degrees, 3=67.5 degrees, 4=90 degrees, 5=112.5 degrees, 6=135 degrees, 7=157.5 degrees, 8=180 degreesFormula: Y0=1/2 (d-2t) cos0 degrees =0.5 (d-2t)Y1=1/2 (d-2t) cos22.5 degrees =0.4619 (d-2t)Y2=1/2 (d-2t) cos45 degrees =0.3536 (d-2t)Y3=1/2 (d-2t) cos67.5 degrees =0.1913 (d-2t)Y4=1/2 (d-2t) cos90 degrees =0Y5=1/2 dcos112.5 degrees =-0.1913dY6=1/2 dcos135 degrees =-0.3536dY7=1/2 dcos157.5 degrees =-0.4619dY8=1/2 dcos180 degrees =-0.5d
Q:10kV and below the distribution cabinet in the room, the basic channel should be higher than the indoor ground level? Which specification is clearly defined?
100MM, check GB50052.53.54. The book in the three is forgotten
Q:Channel steel is mainly used in building structures
Channel steel is a strip of steel with a cross section. Section steel with groove shape. Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. In use, it requires better welding, riveting performance and comprehensive mechanical properties.
Q:Roll an outer diameter of 1688MM groove steel ring, how to cut?
Steel hoop, the outer diameter of 1688MM, with 8# steel roll, theoretical calculation formula for *3.14159=5168mm (1688-43), but this material, placed above the rolling machine to roll bending process, due to tension phenomenon, so roll diameter to be bigger, and the inner groove is also just outside bend channel rolling material should be the theoretical length minus extension length, the best use of section bending machine bending machine die roll, or
Q:How much is the channel steel? How much is one and how long is it?. What is the price of different sizes?
This is too difficult for you to answer, for example: 10# channel steel, the worst wide 10mm, width 5MM, material thickness of about 5MM, the price of about 95 yuan. The national standard is about 150 yuan.
JANG is a professional company specilized in cold bend angle, cold bend U channel and other cold formed sectional steel. Since the established of our company, we aimed to provide the customers qualified product with good price and convenient service.
