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.

Q:The following steel is not section bar, is it? A. thread steel, B. steel pipe, C. track, D. channel steel
In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape. Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:What does "channel weight" mean?
The channel is simply an ideal state of the weight is from the drawing to calculate the weight of steel, but after hot rolling, the size of the actual size and always on the drawings of the deviation, and generally less than the actual weight of theoretical weight.
Q:What is the minimum size of channel steel?
Channel 5# channel, width of 50 mm, 37 mm high leg, thickness 4.5 mm.
Q:How are the two channel welds welded?
Need a connection plate welding, welding parts.
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?
Power distribution cabinet (box), power distribution cabinet (box) and lighting distribution cabinet (box), measuring cabinet (box), is the last stage equipment of power distribution system. Power distribution cabinet is the general term of motor control center.
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:Dry wall hanging marble, I would like to ask the general keel, channel, angle steel with what kind of specifications?
Conventional channel steel has 10#. 8#. 6.3 of the connection length, spacing, and various loads are very large. The angle iron is usually 5#4mm or 5mm and has to be calculated. Generally, it is accessible.
Q:Use two long five meters of 10# channel steel load-bearing frame, the maximum load is?
Set a span of 4.8m, two 10#Q235 channel parallel, as the beam, the required load is concentrated load, the role in the middle of channel.
Q:Installation of floor type distribution box, foundation channel production and installation, the quota should choose which two?
The foundation channel steel production: the foundation channel steel is not installed item containing material, quantity of steel plate, galvanized flat steel, round steel is installed base grounding of the auxiliary channel and. To calculate the foundation channel steel production, making composite iron production, the quantity of round bar, angle steel, flat steel can be unified to channel.
