h steel belongs to the steel market is representative of a product, the reason why it is so named, mainly from the appearance of the design considerations, it is more optimized distribution of cross-sectional area, the strength and weight ratio is more reasonable, and the cross-section is more like the letter H, so have the today's widely known name. In addition to the market can choose the h steel product price, size specifications are also a variety of, so that consumers with different needs can meet different situations and harvest satisfactory results.
A, h steel quality
h steel material is mainly Q235B, Q345B. Q235b is a carbon structural steel
① by the Q + number + quality grade symbols + deoxidation method symbols. Its steel number is crowned with "Q", representing the yield point of the steel, followed by a number indicating the yield point value, the unit is MPa For example, Q235 indicates that the yield point (σs) is 235?MPa carbon structural steel.
② If necessary, the steel number can be marked behind the symbols indicating the quality level and deoxidation method. Quality level symbols were A, B, C, D. Oxygen removal method symbols: F means boiling steel; b means semi-sedated steel: Z means sedated steel; TZ means special sedated steel, sedated steel can not be labeled symbols, that is, Z and TZ can not be labeled. For example, Q235-AF means A grade boiling steel.By GB/T?700 and GB/T?1591 test chemical composition, mechanical properties.
If 1 item is unqualified, it is unqualified.
Second, h steel manufacturers

3, Shandong Xin Ye Steel Co., Ltd. is a collection of production and sales of H-beam steel in one of the manufacturers. Profile specifications, through years of efforts, Shandong Xin Ye Steel Co., Ltd. has become a large-scale domestic steel manufacturers sales base, has with the country's major power plants, boiler plants, petroleum, chemical, machinery and other enterprises have established a stable supply relationship. The company follows the integrity management, the real price, quality service purpose, won the user, expand the market. Products are used in petroleum, chemical, chemical fiber, smelting, pharmaceutical machinery, paper, insulation refrigeration, machinery and equipment, food, electric power, water conservancy, construction, submarine engineering, marine shipbuilding, environmental protection and other industries.
h steel flange are equal thickness, rolled cross-section, so compared to other steel has special advantages, specifically is strong bending resistance, construction is simple, cost savings and structural light weight and other advantages, and we found that although the product is similar in appearance, but on the market can provide similar products to manufacturers to give the pricing is not the same. This is mainly due to the different levels of quality, as well as differences in the service life of the product, making the price difference.
