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:Own attic, choose I-beam or channel
Oneself take attic, suggest to choose I-beam, and choose GB steel, because stainless steel in non GB is more.I-beam is a kind of economical section steel with better mechanical performanceFeatures: I-beamWide flange and large lateral rigidity. Good bending resistance.The two surfaces of the flanges are mutually parallel so that the connection, processing and installation are simple and convenient.Compared with the general steel, the utility model has the advantages of low cost, high precision, little residual stress, no expensive welding materials and welding seam detection, and the cost of steel structure production is saved by about 30%.Under the same section load, the weight of hot-rolled H steel structure is less than that of traditional structure 15%-20%.Compared with the concrete structure, the I-beam structure can increase the use area of 6%, while the weight of the structure can be reduced by 20% and 30%, and the internal force of the structural design can be reduced.The I-beam can be processed into T steel, and the castellated beams can form various section forms to meet the demands of engineering design and manufacture.
Q:Does anyone know how to calculate the volume of channel steel?!
Theoretical calculations can be used: sectional area * length. There are sectional sizes in the specifications of channel steel labels. The sectional area and volume shall be calculated first. When measuring the sectional area, the grid paper can be used. Of course, the accuracy is limited.
Q:What is the specific weight of 10# channel steel?
Hot rolled light channel steel [(YB) 164-63]Height =100, leg width =46, waist thickness =4.5, average leg thickness =7.6, inner arc radius =7.0, leg end arc radius =3.0, sectional area (cm2) =10.9, theoretical weight (kg/m) =8.59
Q:What is the standard for channel steel execution?
The delivery length of channel steel is divided into two kinds: foot length and double foot length, and the allowable difference is stipulated in the corresponding standard. The length of domestic channel selection range according to specifications, divided into 5 - 12M, 5 - 19m, 6 - 19m three. The length of imported channel steel is generally 6 - 15m.
Q:What is the minimum size of channel steel?
Channel steel is a strip of steel with a cross section. Section steel with groove shape.
Q:What are the acceptance criteria for channel steel?
The raw material for producing 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:What angles, angles and channels are used in general? Please try to be specific?
Profiles are commonly used in construction for steel structures, plant buildings (single deck, multiple), adding (inserting) layers, and simple and independent components: Roofing frames, interior and exterior steel staircases, etc.In steel construction plants (buildings), what you call those profiles are useful
Q:What does channel 100*48*5.3-39 mean? (what are the specific parameters?)
That is to say, 10# channel steel, size is 100 wide, leg height 48, thickness 5
Q:Is it OK to use the channel steel to do the Overhanging Scaffold? Is there any difference between the cantilever scaffold made of I-beam and channel steel?
Channel steel, of course. The difference between the channel steel and the I-beam is that the cross section of the steel beam overlaps with the center of the shaft, while the channel steel deviates slightly from the limit; the load is the whole stability of the channel. It is of little significance in construction.
Q:The back of the channel steel deviates from the 30mm. The upper and lower iron plates are welded at intervals. Is the cross section resistance moment the sum of the two? No, is it big or small? Thank you
The direction of the X axis distance of the centroid and centroid of single channel and two channel combination from coincidence (the same), so the moment of inertia of the two combinations of two single channel channel is equal to the moment of inertia and resistance moment and is also. (resistance moment = moment of inertia / centroid distance)The Y axis direction, back to the departure from the 30mm two, the centroid distance than the centroid of the single channel combination channel distance increases 15mm, moment of inertia is the centroid distance square by channel section, so a combination of two channel resistance moment is far greater than the two single channel and.
