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:Double building with channel steel, good barrier, nail board, can you do toilet?
It is best not to do the toilet (for short periods of time can be), a long time after their own great wall tiles falling force, the board will damp, future risks are great (unless you do a few times waterproof layer and a reinforcement layer, but the price is too high, you can consider the use of red brick walls)
Q:Span 3.9. Can I make attic with channel No. 10?
Channel 10 is a little small, at least with 12# channel steel.
Q:What's the difference between channel type 25a#, 25b# and 25c#?
Channel steel is a strip of steel with a cross section. The specifications of the method, such as 120*53*5, mean waist height of 120 mm, leg width of 53 mm channel, waist thickness of 5 mm channel, or called 12# channel. 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, such as 25a#, 25b#, 25c# and so on. 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 in building structures, vehicle manufacturing and other industrial structures, and channel steel is often used in conjunction with i-beam.
Q:Cautions for surface zinc spraying on channel steel
Thermal spraying zinc sacrificial anode protection is a single layer of zinc, the corrosion rate depends only on the zinc layer thickness and dissolution rate and inorganic zinc in addition to the protection of zinc layer, the complex chemical changes generated by lithium silicate, zinc silicate, carbonate can better cover metal surface. Secondly, the high porosity of thermal sprayed zinc (3% ~ 5%), another blocking agent brushing waterborne inorganic zinc rich coating with low porosity (usually below 1%), which can be used for thermal spraying zinc surface sealants. In addition, the process of thermal spraying zinc complex, need for high temperature and high pressure and inorganic zinc spraying, brushing is can be flexible operation, the overall comparison, but low cost inorganic zinc.
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:Roll an outer diameter of 1688MM groove steel ring, how to cut?
Steel hoop, the outer diameter of 1688MM, with 8# steel roll, theoretical calculation formula for *3.14159=5168mm (1688-43), but this material, placed above the rolling machine to roll bending process, due to tension phenomenon, so roll diameter to be bigger, and the inner groove is also just outside bend channel rolling material should be the theoretical length minus extension length, the best use of section bending machine bending machine die roll, or
Q:How heavy is channel 1, 16? How do you calculate the formula?
17.2Kg16# channel mass per unit is 17.2Kg, this often used by people remember, the formula is 17.2 x 1=17.2Kg
Q:I want to know what kind of steel is this type of steel, such as channel steel and die steel?
Belong to section bar. 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:Is the channel 20 the same as the channel 20b?
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.
Q:How do you calculate the weight of 100 channel steel?
CAD drawing can also be used to calculate the cross-sectional area of 100 channel, or other ways to first calculate the cross section area of 100 channel.
