Applications of MS Channel:

The MS 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 MS 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.

Q:Channel
In use, it requires better welding, riveting performance and comprehensive mechanical properties. The raw material steel billet for 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: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 bearing capacity
Under the maximum bending moment calculation formula: M=1/8GL?? -1/8gL??, (L=600cm, G: the calculation of the maximum uniform load, G: ibid.)
Q:Duplex 3, the main beam 3.6 meters, span 4.5 meters wide, steel structure, with 8 channel steel can be, how much space? Or how to make it reasonable? Daily life bears little weight.
How reasonable?. Have to tell you the plane of the room, how to do it, according to some careful design, and then you see the satisfaction of the design results signed and approved. It'll take a lot of time. I can't help you.
Q:The parameters of the channel steel of Q235B
Q235B is carbon structural steelIt consists of Q+ numeral + quality grade symbol + deoxidization method symbol. The steel dubbed "Q", representing the yield point of steel, behind the digital representation of the yield point value, in units of MPa such as Q235 (s) said the yield point for carbon steel 235 MPa. The necessary grades can be marked behind said deoxidation methods of quality grades and symbols. The quality class symbols are A, B, C, and D respectively. Deoxidation method notation: F means boiling steel; B represents semi killed steel: Z indicates calm steel; TZ stands for special sedation steel; calm steel is not marked; Z and TZ are not standard. For example, Q235-AF indicates a class of rimmed steel.
Q:Is channel steel cold rolled or hot rolled?
Channel steel is divided into ordinary channel steel and light channel steel. Standard Specification for hot-rolled plain channel steel is 5-40#. Specifications for hot rolled flexible channel steel supplied by supply and demand agreement are 6.5-30#. Channel steel is mainly used for building structures, vehicle manufacturing, other industrial structures and fixed plates, cabinets, etc., and channel steel is often used in conjunction with i-beam.
Q:Channel 10 is calculated, if the price per metre is calculated
No. 10 channel steel is calculated, that is to say, the standard weight, that is, all channel sizes have reached the standard, our national standard No. 10 channel steel theoretical weight is 10.007 kg / meter.
Q:Rusting of Q235 steel plate and Q235 channel steel
It shouldn't be a problem. See the GBT 19879-2005_ steel plate for the building structure6.5 surface qualityNo cracks, bubbles, scars, folds, inclusions, and iron oxide sheets are allowed on the surface of the 6.5.1 steel sheet. Steel plate shall not be layeredThe surface of 6.5.2 steel plate is allowed not interfere with the inspection of surface defects of thin oxide scale, rust, pressure by iron oxide shedding caused no significant surface roughness, scratch, indentation and other local defects, but its depth not greater than half of the tolerance of thickness, and should ensure that the minimum thickness of steel plate.
Q:Channel 20A? What's the matter?
Not 20A. It should be 20A. The letters in the back of the numbers are different in meaning. The letters behind the channel must be lowercase (waist thickness is different).20 represents section height 200mm of channel steel, 200*73*7.0 theoretical weight 22.637
Q:Can the bypass of the overhanging layer on the site be made of channel steel? How can I put the channel steel, if possible?
The cantilever end of 6.10.7 steel cantilever beam shall be provided with a fixed point which can make the scaffold stand firmly with the steel beam. The location shall be no less than 100mm at the end of the cantilever beam. When the 6.10.8 anchor position is set on the floor slab, the thickness of the slab shall not be less than 120mm.
