HE300A European standard H-beam 290*300*85*14 size differences and features.
HE300A European standard H-beam is a common construction steel, and its size is 290*300*85*14。Compared with other types of H-beams, HE300A has certain differences in size. This article will introduce the size difference and characteristics of HE300A European standard H-beam.
1. Size differences.
According to its cross-sectional size, European standard H-beam can be divided into narrow flange H-beam (Hz), wide flange H-beam (HW) and H-beam pile (HP). Among these types, HE300A belongs to narrow flange H-beams. Narrow flange H-beams have a smaller flange width and a larger height compared to wide flange H-beams. Therefore, the size of HE300A is 290*300*85*14, compared with the wide flange H-beam, its flange width is smaller, while the height and thickness are larger.
In addition, the cross-sectional area and cross-sectional moment of inertia of HE300A are also different from other types of H-beams. According to the calculated results, the cross-sectional area and cross-sectional moment of inertia of HE300A are 156., respectively9cm and 2465cm. Compared to other types of narrow flange H-beams, HE300A has a larger cross-sectional area and a smaller cross-sectional moment of inertia.
2. Features. 1.Structural stability.
Due to the small flange width and large height of HE300A, its structural stability is better when subjected to large bending moments. In building structures, the use of HE300A can improve the load-bearing capacity and stability of the structure.
2.Lightweight construction.
Compared to other types of H-beams, HE300A has a lighter weight. Therefore, the use of HE300A in the building structure can reduce the dead weight of the structure and facilitate the construction operation. In addition, the lightweight construction is also easy to transport and handle.
3.Economical.
HE300A's ** is relatively low, so in some construction projects with limited budgets, the use of HE300A can reduce engineering costs. In addition, due to its lightweight characteristics, it can reduce the cost of transportation and handling.
To sum up, HE300A European standard H-beam has the characteristics of good structural stability, lightness, economy and applicability. In building structures, the use of HE300A can improve the load-bearing capacity and stability of the structure while reducing engineering costs.
