Ordinary beam, light beam flange is variable section by a thick web portion, the outer thin; H-beam: HW HM HN HEA HEB HEM and other beam flange is equal section ordinary beam, light word Steel has become the national standard, ordinary 10 # I-beam is equivalent to I100 internationally (such as 10 # channel also corresponds to channel U100) (because the standard implementation of the different countries, resulting in their specifications have subtle differences) H Type also called wide-flange beam beam, HW HM HN from the European standard, HEB German standard I-beam, which HW, HN beam has been widely used and produced in our country. HEA HEB HEM in many German plan would see, in the domestic market is still difficult to buy. In the domestic steel works, if you can use less steel and other specifications for welding splicing. And large, then, consider the use of the mechanical properties generally comparable HW, HN steel instead. HW beam is mainly used for reinforced concrete frame structure column steel core columns, also known as King of the steel column; mainly used in steel column HM steel flange height and width ratio of roughly 1.33 ~ 1.75, mainly in steel used to make steel frame columns to withstand dynamic loads to do frame by frame beam; for example: device platform HN steel flange height and width ratio is greater than or equal to 2; the main purposes for the ordinary beam girder steel equivalent HN; ◆ work word steel, whether ordinary or light, because cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two spindles large difference, it can only be used directly in its web plane Bending The member or its composition lattice force member. For axial compression members or perpendicular to the plane of the web as well as curved components are not suitable, which it has significant limitations on the scope of application. ◆ H-beam cutting surface profile belongs to efficiently and economically (there are other cold-formed thin-walled steel, pressure plate, etc.), due to a reasonable cross-sectional shape, they can make steel more play performance, improve the carrying capacity. Unlike ordinary it is h-shaped steel flange was widened, and the inner and outer surfaces generally parallel, so that makes it easy to connect with high-strength bolts and other components. Constitute series reasonable size, complete model, ease of design choice. The scope of the ordinary I-beam, light beam, due to the cross-sectional dimensions are relatively high, narrow, so the cross-sectional moment of inertia of the two main sleeve large difference in the application which it has significant limitations . The use of beam shall be chosen according to the requirements of design drawings. Sized H-beam cutting plane belonging to efficient and economical type of steel (Others are cold-formed thin-walled steel, pressure plate, etc.), due to a reasonable cross-sectional shape, they can make steel more play to the effectiveness and improve the bearing capacity of the CD. Unlike ordinary beam it is H-beam flanges were widened, and inner and outer surfaces generally parallel, so that makes it easy to connect with high-strength bolts and other components. Constitutes a reasonable size, complete model, ease of design choice. In the structural design of the beam selection should be based on its mechanical properties, chemical properties, weldability, structure, size and other reasonable choice of beam for use. H-beam flange welding process are of equal thickness, there are rolling cross-section, but also by the composite section consisting of three plate welding. Ordinary beam are rolling cross-section, because the production process is poor, inner flange edge has a 1:10 slope. Rolled H-shaped steel beam with only a level different from the common roll, because of its wide flange with no inclination (or slope is very small), and thus should be added a set of vertical rolls simultaneously rolls, thus its rolling mill technology and equipment than the general complexity. China can produce the maximum rolling H beam height of 800mm, more than the combined section can be welded. H steel flange suitable for narrow beam or bending member, and wide flange h and h-beam steel pile is applicable to axial compression members or bending member. Ordinary beam, light beam as compared with HW, HN steel, etc. under the weight of the premise, w, ix, iy H-beam not as a sale: landline: 0635-8388655 landline: 0635-8387855 Mobile: 15266455558 sales of two Department: landline: 0635-8218485 landline: 0635-8215458 Mobile: 13290269373 Sales three: landline: 0635-5088885 Mobile: 15553672637 Fax: 0635-8330114 Online qq: 2480265557 Account Name: Liaocheng Shun Metallurgical Products Co., Ltd.

Steel table can be found from its maximum available shear strength T Tmax = Q / Ib [BH ^ 2 / 8- / 8] where: Tmax is the maximum shear strength. T on behalf of the available shear strength into it, the beam can be calculated to withstand the maximum load. Q is a uniform load I beam cross-sectional moment of inertia to be Richard (cm ^ 4) in the steel sheet. The maximum width B of the I-beam cross-section. b h is the minimum width of the beam cross-section to the minimum width of the I-beam cross-section height. Calculate the height of the normal stress of H is the maximum width of beam cross section: Ysigma = M / WM = biggest moment = load multiplied by the distance W = flexural modulus. Set Ysigma = maximum allowable stress, the maximum load can be drawn.

Q235C beam A sixth grade on the Fitch rating scale, Bi Mudi (Moody's) at the end of last year after Japan lowered the ratings even lower level, lower than the S & P (Standard & Poor's) rating levels. Q235C beam Fitch said: "The main weakness of Japan's sovereign credit rating is the high level of government debt and increasing Fitch expects the end of 2015, the total amount of Japanese government debt to gross domestic product (GDP) ratio. will rise to 244%, which would be the highest rate among all sovereign bonds by ratings far ahead. "Q235C beam over the past 20 years, the rapid growth of Japanese government bonds, because the rise in social security spending, tax revenues stagnate, but successive governments trying to use fiscal stimulus to restore growth. Q235C beam, however, the Japanese government has been able to take advantage of the huge domestic savings pool to very low interest rates to finance themselves. This means that Japan has never come close to the debt crisis, although there have been predicted many times in this regard. Q235C sovereign ratings director of Fitch's Asia-Pacific high beam Haldex (AndrewColquhoun) said that this rating reflects the extreme position of Japan: weak public finances and economic growth, but the government powerful little debt.
