There are 6 kinds of 300 series H steel, 3 kinds of wide flange, respectively HW294*302*12*12, single weight 83.5kg/m, HW300*300*10*15, single weight 93kg/m, HW300*305*15*15, single weight 105kg/m, 1 kind of middle flange, There are HM294*200*8*12, single weight 55.8kg/m, narrow flange, HN298*149*5.5*8, single weight 32kg/m, HN300*150*6.5*9, single weight 36.7kg/m.

〣H beam (mm)300×150×4.5×8 data represent what

The shape of H type steel is actually more like a long I-shape, now according to I-shape to describe the meaning of H300×150×4.5×8: between the upper plate to the lower plate plate outside to outside height is 300, the upper and lower two plates (also on the wing plate) plate width is 150, thickness is 8, the middle of a plate width of 300-8-8=284, thickness 4.5.

In summary, each part of its presentation format is H (the sum of web width + upper wing thickness + lower wing thickness) x wing width x web thickness x wing thickness. This specification of yours should belong to high frequency welding H steel.

Extended information:

The section modulus, moment of inertia and corresponding strength of H beam are obviously better than that of ordinary I beam with the same single weight. Used in different requirements of the metal structure, whether under bending moment, pressure load, eccentric load show its superior performance, can greatly improve the bearing capacity than ordinary I-steel, metal saving 10% ~ 40%.

H beam has wide flange, thin web, many specifications and flexible use, which can save 15% ~ 20% metal in various truss structures. Because the flange is parallel inside and outside, and the edge end is at a right Angle, it is easy to assemble and combine into various components, which can save about 25% of the welding and riveting work, and greatly accelerate the construction speed of the project and shorten the construction period.
