Applications of Cold-Rolled MS C Channel:

The Cold-Rolled MS 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 MS 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.

 Cold-Rolled MS C Channel

 

 

 Production Flow of Cold-Rolled MS 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:How about the Y-Y moment of inertia in the form of hot rolled channel steel Iy?
Among them, H, B, D and T are the corresponding parameters on the standard. B leg root thickness, a thickness of leg point or T = (a + b) divided by 2, R for leg root radius, R leg tip radius, Z standard centroid value, ^2 said in front of the results in parentheses square, ^3 cube, X said after the power multiplied by the other the local sign is omitted, said by slash.
Q:What does channel 20# mean?.
20# channel steel means that the middle width is 200mm. There are two kinds of specifications: A and B: 20#A:200*73*7, 20#B:200*75*9, sizes indicate middle width * leg width * middle thickness.
Q:What's the weight of the 4 meter long 18 channel steel?
The weight of the load is also related to the placement of the channel and the material of the channel. Specifically, you can refer to the formula of the relevant sections of the mechanical design manual.
Q:Could you tell me the theoretical weight and size of 16 and 18 channel steel?
Channel steel 16#a specifications 160x, 63x, 6.5mm, theoretical weight of 17.24 kg per meterChannel steel 16#b specifications 160x 65 8.5mm, theoretical weight of 19.752 kg per meterChannel steel 18#a specifications 180X, 68x 7 mm, theoretical weight of 20.174 kg per meterChannel steel 18#b specifications 180 X70 x9mm, theoretical weight of 23 kg per meter
Q:What are the acceptance criteria for channel steel?
At present, domestic channel steel specifications from 5 - 40, that is, the corresponding height of 5 - 40cm. At the same height, the light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. 18 - 40 is large channel steel, 5 - 16 channel steel is medium channel steel.
Q:What do you mean by "A" in the channel type?
The same waist height, according to its thickness is divided into a, B, B, C or a.A thin waist is the most.The width of their legs is equal to the waist thickness difference, that is, the real leg (not including waist thickness) is the same length, and the average leg thickness is the same.
Q:28# how to butt joint channel?
If the gap between the two weldment is not conducive to welding, it can be welded with a piece of steel plate. If the assembly gap is reasonable, direct rust removal and welding can be done.
Q:How can channel A and B be distinguished?
Of the same height, type B has wider legs and thicker waist than A.
Q:What is the elastic modulus of steel?
When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus. The elastic modulus of the unit is dyne per square centimeter. "Modulus of elasticity" is a physical quantity describing the elasticity of matter. It is a general term. It can be expressed as "Young's modulus", "bulk modulus" and so on.When it is difficult to cause confusion, the modulus of elasticity of a general metallic material refers to Young's modulus, i.e., positive modulus of elasticity.Unit: E (elastic modulus) MPa (MPa)
Q:In the steel structure of steel purlin 160*60*20*2.5 is what mean?
The horizontal component roof length distribution, located in the main rafters, support secondary rafters. The ancient houses used to stir up the rafters, roof bars made of, is one of the main components of the house, also called the boat (or sub truss northern dialect).
