Applications of CR C Channel:

The CR 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 CR C Channel:

1.The hot rolled 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 hot rolled 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.

 

 CR C Channel

 

 Production Flow of CR 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 hot rolled channel steel should be put onto the cooling bed to make the temperature low.

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

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

Q:Surface area of channel steel
20A channel steel is 200mm in height and 73mm in width.Area = length * (200*2+73*4)
Q:Difference between steel channel and channel steel!
Steel trough is made of cold rolled steel plate, channel steel is used by rolling mills and billets rolled out of products.
Q:Relationship between H steel and I-beam, C section steel and channel steel?
First of all, C steel after cold bending of hot coil and high strength, good tenacity, and channel production can save 30% compared to the same intensity of raw materials, is a direct channel by steel companies, the thickness is greater, it is groove shaped cross section. Second, C steel is usually used for steel structure building wall beam, beam, bracket or other building components, widely used in the activity room, also can be used in machinery manufacturing industry. Channel steel is mainly used in building structures, vehicle manufacturing, and other industrial structures, often with the use of i-beam. Although the two steels are used in building structures, they are used in different ways.
Q:Is section steel the same as channel steel?
Dissimilarity。 Channel steel is a kind of section steel. Section steel includes angle steel, channel steel, I-beam, H steel and so on
Q:What is 16a# channel steel?
Specific dimensions are as followsh=160mm;b=63mm;d= 6.5mm;t= 10.0mm;r=10.0mm;r1=5.0mm
Q:Is it better to cast a pipe or a channel steel?
The deadweight of concrete is too large to be calculated in tons. If the span is too large, with a reinforced concrete beam reinforced swing down from the middle, on both sides is the main force, the deformation of beam steel tension, resulting in bearing wall deformation.
Q:Formula for section modulus of channel steel
Wx:1. first calculate the cross-sectional area of the flange and web 2. respectively; find out the flange and web section of the center axis x1-x1, x2-x2; 3. were found the whole section X-X from the spindle flange and web section of the distance from the center of Y1, Y2, (Y1 for channel 0, x1-x1 is X-X; 4. spindle) are calculated respectively. The moment of inertia of flange and web sections of x1-x1, x2-x2, and the moment of inertia of flange part of the shift shaft to the spindle, X-X, flange and web can be obtained by adding the Ix section of the X-X moment of inertia; 5. Ix / H/2 is Wx.
Q:Calculated weight of channel steel
A calculating example channel (kg/m) W=0.00785 * [hd+2t (B? C D (+0.349) R2? C R 2 m h=) per channel] weight high b= leg length d= t= average thickness of R= thick waist leg inner arc radius r= end arc radius for 80 mm * 43mm * 5mm. From the metallurgical products directory found the channel of T is 8, R is 8, R is 4, per M weight =0.00785 * [80 * 5+2 * 8 * (43? 5 C) * +0.349 (82? C4 2)]= 8.04kg
Q:Channel loading
It is assumed that the channel material is Q235, model 14a, vertical, 3.5m, center force, and the maximum load is P.
Q:How to choose angle steel and channel steel for dry hanging stone?
A qualified design unit is required. Material selection as required.
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.
