Applications of UPN Channel Steel:

The UPN Channel Steel 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.

Q:What does channel C20 mean?
Channel C20 represents 20# channel steel. C is the symbol of channel steel.Channel steel is a strip of steel with a cross section. Its specification means: such as 120*53*5, which means that the waist height is 120 millimeters, the width of the leg is 53 millimeters of channel, the waist is 5 mm thick channel, or called 12# 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 25a#, 25b#, 25c# and so on.
Q:How to judge whether the joint of steel structure is rigid or hinged, as shown below, the steel beam and steel column are all channel steel and welded through weld joint.
I don't think we can generalize. The connection of the steel structure is mainly welding seam connection and bolt connection; generally speaking, the welding seam is just connected, but the bolt is not necessarily. The bolt section, there are friction; if the friction force of the bolt section is far greater than the moment, so it can be identified as rigid; if the two force magnitude close, then identified as articulated, and to check the moment.
Q:12# how much is a channel steel? The length is 6 meters. GB steel channel should be used
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.
Q:Installation of floor type distribution box, foundation channel production and installation, the quota should choose which two?
Floor type distribution box installation cannot apply the distribution cabinet installation, and should set floor type of distribution box installation quota; installation set foundation channel steel foundation channel steel installation item.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.
Q:How big is the channel used for the 4 metre span?
The same height of the I-beam, if there are several different leg width and waist thickness, should be added on the right side of the model a, B, C to distinguish, such as 32a#, 32b#, 32c# and so on. The I-beam is made of ordinary I-beam and light I-beam, and the specification for hot-rolled ordinary I-beam is 10-63#. Standard Specification for hot-rolled ordinary I-beam supplied by supply and demand agreement is 12-55#. I-beam is widely used in various building structures, bridges, vehicles, supports, machinery and so on.
Q:Six meters long, standard 10 channel steel, theoretical weight
Channel steel is a kind of carbon structural steel used for construction and machinery. It is a complex section steel. Its cross section has a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing, etc.. 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%.
Q:Specific difference between channel steel, cold-formed steel channel, hot plate and cold plate
Because of the difference of production process between them, the performance of them is different greatly. The strength of hot rolled steel or hot-rolled steel is lower than that of cold rolling, but the plastic deformation ability is stronger.
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:How to anchor the channel?
On the basis of the embedded 20 thick steel plate, with high-strength bolts or chemical bolts fixed, and then use the stiffener to clamp the middle of the channel, and use high-strength bolts to connect.
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.
