Hot-Rolled H-Beam Steel (GB 11263-89)
Hot-rolled H-beam steel is a kind of economic and efficient cross-section material with better mechanical properties and better performance in production and construction. In recent years, it has become an important component of modern high-rise construction, large-span bridges, heavy transport machinery, large ships, and other engineering constructions. With the high-rise construction of China, the demand for hot-rolled H-beam steel continues to increase.
The H section steel produced by hot rolling has a good cross-sectional shape, uniform mechanical properties, excellent welding performance and comprehensive properties, so it is widely used in industrial and civil construction and other fields. The H section steel products produced by hot rolling can be divided into narrow flange and wide flange according to different widths of the upper and lower flanges.
Hot-rolled H-beam steel is the kind of steel used to produce hot-rolled H-beams. Hot roll H-beams are hot rolled structural steel sections produced in accordance with the GB11263-89 standard. This code stated the hot-rolled HDMP production specifications. It is extremely popular with the advantage of low cost and easy production.
GB11263-89 is the standard for hot-rolled H-beam steel. This standard was formulated by the Ministry of Metallurgical Industry in 1989. It specifies the size of hot-rolled H-beam steel and its limit deviation, shape, strength and technical requirements. The standard applies to hot-rolled H-beam steel with a minimum nominal height, height ratio and minimum nominal yield strength not lower than 235MPa.
The basic performance of hot rolled H-beam steel is often specified by the specificatio7ns of the hot-rolled H-beam steel (GB 11263-89); however, for special projects, the specifications need to be customized according to the specific requirements.
Hot rolled H-beam steel has the characteristics of good section performance and economy.Therefore, it is widely used in industries such as steel making, engineering plant, bridges and buildings. The H-beam steel is composed of web and flange, and it needs to withstand a certain amount of bending moment in the middle of the web. Therefore, the actual strength of the steel should be higher than the nominal strength specified in the standard.
Hot rolled H-beam steel has the advantages of simple structure and convenient construction, light weight, good section performance and high overall strength. It is widely used in various types of buildings, bridges, heavy machinery and various civil engineering structures. Hot rolling is the most commonly used process to produce H-beam steel. The hot-rolled H-beam steel has good welding performance and can be welded by various welding methods.
In conclusion, Hot-rolled H-beam steel is the kind of steel used to produce hot-rolled H-beams. It is the most common process used to produce H-beam steel. It has the advantages of good section performance and economy. The H-beam steel is composed of web and flange, and it needs to withstand a certain amount of bending moment in the middle of the web. Therefore, the actual strength of the steel should be higher than the nominal strength specified in the standard. Hot-rolled H-beam steel is widely used in various types of buildings, bridges, heavy machinery and various civil engineering structures.
