Relationship between H steel and I-beam, C section steel and channel steel
The classification of C type steel is numerous, including: galvanized, hot galvanized cable tray, glass curtain wall, ranging in shape, edge line, car profile. Channel steel can be divided into light channel steel, ordinary channel steel, hot rolled channel steel, cold bend equilateral / unequal channel steel, cold bend inner / outer side channel steel channel.
First of all, C steel after cold bending of hot coil and high strength, good tenacity, and channel production can save 30% compared to the same intensity of raw materials, is a direct channel by steel companies, the thickness is greater, it is groove shaped cross section.?Second, C steel is usually used for steel structure building wall beam, beam, bracket or other building components, widely used in the activity room, also can be used in machinery manufacturing industry. Channel steel is mainly used in building structures, vehicle manufacturing, and other industrial structures, often with the use of i-beam. Although the two steels are used in building structures, they are used in different ways.
Difference: 1. Under the condition of the same amount of steel, H steel can do more rigidity and stability than I-beam, and its resistance to bending and bending is better than that of I-beam2, the shape of H steel on the lower flange far wider than I-beam3, the process of H steel can be rolled or welded, steel are rolled
1, whether ordinary I-shaped steel is mainly type or light, because the section size are relatively high and narrow, so the moment of inertia of the main sections of the two sleeve is larger * so, generally only can be directly used in the web plane bending member or the composition of lattice stress component. It is not suitable for the axial compression member or the bent member perpendicular to the web plane, which has great limitations in its application2 and H steel is a kind of high efficiency economic section profile (other cold bending thin wall steel, pressed steel plate, etc.), because of the reasonable cross-section shape, they can make steel more effective, improve the cutting capacity. Unlike ordinary I-beam, wing embroidery of H steel is widened, and the inner and outer surfaces are usually parallel, so that it is possible to connect the high strength spiral with other components. Its size constitutes a reasonable series, complete model, easy to design and use. H type steel rolling is different from ordinary I-beam with only one set of horizontal roll, the wing sash is wide and has no inclination (or inclination is to be very small), a group of vertical roll and roll. Therefore, the rolling process and equipment are more complex than the ordinary rolling mill.
