Usage/Applications of Channel Steel:  

Channel Steel is usually used for building structure, vehicle manufacturing and other industrial structure and often used with i beam.

In details,  the channel steel belongs to carbon structural steel which is applied to in the field of construction and machinery. The 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 channel steel must possess perfect welding property, riveting property and mechanical property and so on.

Package & Delivery of Channel Steel:

The steel u channel 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.                                                                                                

And steel u channel could be loaded into 20ft or 40ft container, or by bulk cargo. If the weight of each bundle reaches less 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.                                                                                                          

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

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

Production Flow of Channel Steel:

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.

Q:Relationship between H steel and I-beam, C section steel and channel steel?
The shape of H steel on the lower flange far wider than I-beam
Q:What are the advantages of channel steel?
According to the structure theory of channel, point in the wing section, i.e. channel should be upright, not lying. Therefore, the channel steel can change the structure of the building and save the building materials.
Q:What is the wall thickness of national standard 8* channel steel?
National Standard No. 8, channel height 80, leg width 43, waist thickness 5, hardware manuals are available.
Q:What is the square bevel washer used for channel steel?
The inclination of the channel steel and the angle of the square bevel washer coincide with the standard.
Q:10# how much is it per kilogram of channel steel?
National standard:Hot rolled plain channel [(GB) 707-65] (unit mm)Height =100, leg width =48, waist thickness =5.3, average leg thickness =8.5, inner arc radius =8.5, leg end arc radius =4.25, sectional area (cm2) =12.74, theoretical weight (kg/m) =10.00
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:Channel steel is mainly used in building structures
They are divided into ordinary channel steel and light channel steel. The specification of hot-rolled ordinary channel steel is 5-40#, and the specifications of the hot rolled channel steel supplied by both sides of supply and demand agreement are 6.5-30#.
Q:14# dimension of channel steel and weight per metre?
Specification for dimensions and weight of hot rolled ordinary channel steel14#a height (H) 140, leg width (b) 58, waist thickness (d) 6, theoretical weight 14.535 kg14#b height (H) 140, leg width (b) 60, waist thickness (d) 8, theoretical weight 16.733 kg
Q:No. 20 I-beam span 3 meters, fixed on both sides, what is the maximum weight to bear? No. 10 channel steel, span 2.5 meters?
I-beam is also called steel girder (English name Universal Beam). It is a strip of steel with an I-shaped section. I-beam is divided into ordinary I-beam and light I-beam, H steel three. It is a section steel whose shape is trough.
Q:What material does hot-dip galvanized channel belong to?
Because the hot plating, and basically not stainless steel, I guess it should be carbon steel, which specific material is not clear, the most common is Q235 channel steel.
