British standard I-beam 203*203*46 size
The use of ordinary I-beam is equivalent to HN steel;The I-beam whether ordinary or light, because the section size are relatively high and narrow, so the moment of inertia of section two of the spindle is larger, so it only can be directly used in the web plane bending member or the composition of lattice stress components. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application.
H type I-beam is also called wide flange I-beam, HW, HM, HN originated from European standards, HEB is the German standard of I-beam, of which HW, HN I-beam has been widely used in our country and production. HEA HEB HEM will be seen on many German designs and is hard to buy on the domestic market. In the domestic steel structure engineering, if the quantity is few, then may use the specification steel plate to carry on the welding splicing. In the case of large quantities, it is usually considered to use mechanical properties comparable to those of HW and HN steel.
I-beam is mainly divided into ordinary I-beam, light I-beam and H steel three.Ordinary I-beam, light I-beam flange is variable cross-section, depending on the thickness of the web, the external thin; H steel: HW, HM, HN, HEA, HEB, HEM and so on, the flange of I-beam is a uniform sectionOrdinary I-beam, lightweight I-beam has formed the national standard, the common 10# I-beam is equivalent to the Internet I100 (such as 10# also channel equivalent channel (U100) for the implementation of the standards of different countries, which have subtle differences in their specifications)
The main specifications of the available contour I-beam section size (mm) expressed in high waist leg width (H) * (b) * (d) mm thick waist numbers, such as I160 x 88 x 6, namely said waist height 160mm, waist leg width 88mm, thickness 6mm i-beam. I-steel specifications are available models (Tex) said, showing the type of waist high number of centimeters, such as waist high 160mm I-beam type I 16#. The same as the waist high beam, there are several different leg width and waist thick, need to add code in the model (also known as the right corner) a or B or C to make a difference, such as 32a#, 32b#, 32c# etc..
