What are the application characteristics of I-beam steel, channel steel and Angle steel? 


Steel shapes is a kind of bar steel with a certain cross-section shape and size, mainly including I-steel, channel steel, Angle steel, H steel, steel sheet pile and so on. According to the section shape, the section steel is divided into simple section steel and complex section steel (special-shaped steel). The former refers to square steel, round steel, flat steel, Angle steel, hexagonal steel, etc. The latter refers to I-beams, channels, rails, etc.



According to the different smelting quality of steel, steel is divided into ordinary steel and high-quality steel. Ordinary steel is divided into large steel, medium steel and small steel according to the current metal product catalog. Ordinary steel according to its section shape can be divided into I-steel, channel steel, Angle steel, round steel and so on.

Application characteristics of Angle steel

Angle steel: commonly known as Angle iron, it is a long steel bar with vertical angles on both sides. There are equal angles and unequal angles. The two sides of equilateral Angle steel are equal in width, and its specifications are expressed in millimeters of side width × side width × side thickness. Angle steel can be composed of different stress components according to the different needs of the structure, and can also be used as a connection between the components. It is widely used in various building structures and engineering structures, such as beams, Bridges, power transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks and warehouse shelves.

Channel steel application characteristics

Channel steel is a long strip of steel with a groove-shaped cross-section. Channel steel is divided into ordinary channel steel and light channel steel. Channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, and channel steel is often used with I-steel.

Application characteristics of I-beam

I-beams, also known as steel beams, are long strips of steel with I-shaped sections. Its specifications are expressed in millimeters of waist height (h)* leg width (b)* waist thickness (d), I-steel is divided into ordinary I-steel and light I-steel, which is widely used in various building structures, Bridges, vehicles, supports, machinery and so on.

H-shaped steel application characteristics

Hot rolled H-beam steel has excellent mechanical properties and excellent service performance by distributing the aspect ratio of section size reasonably according to different applications. The design style is flexible and rich. In the case of the same beam height, the opening of the steel structure is 50% larger than that of the concrete structure, which makes the building layout more flexible. Light structural weight. Compared with the concrete structure, the weight of the structure is lighter, the reduction of the structure's weight reduces the internal force of the structure design, which can make the building structure foundation treatment requirements are low, the construction is simple, and the cost is reduced.

The steel structure based on hot-rolled H-shaped steel has scientific and reasonable structure, good plasticity and flexibility, and high structural stability, which is suitable for building structures with large vibration and impact loads and strong resistance to natural disasters, especially for some building structures with multiple earthquake zones. Compared with the concrete structure, the section area of the steel structure column is small, which can increase the effective use area of the building, depending on the different forms of the building, can increase the effective use area of 4-6%. Compared with welding H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, low residual stress, and good appearance and surface quality. Easy machining, structural connection and installation, but also easy to remove and reuse.

The use of H-shaped steel can effectively protect the environment, which is reflected in three aspects: first, compared with concrete, dry construction can be used, resulting in less noise and less dust; Second, due to the reduction of self-weight, less soil extraction for foundation construction, less damage to land resources, in addition to a large reduction in the amount of concrete, reduce the amount of rock excavation, conducive to the protection of ecological environment; Third, after the service life of the building structure expires, the amount of solid waste generated after the structure is dismantled is small, and the recycling value of scrap steel resources is high.

The steel structure based on hot rolled H-shaped steel has a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, easy installation, easy quality assurance, and can be built into a real house production factory, bridge production factory, industrial plant production factory, etc. The development of steel structures has created and driven the development of hundreds of new industries.
