H-beam steel because of the appearance of a more special, similar to the letter H, so have the name today, its structure is more stable, performance parameters and service life of the performance is also very good. And as a maturing steel industry is representative of one of the products, today's h-beam has a series of satisfactory production line, corresponding to the number of types are also relatively rich, basically different needs of consumers can be used to get a good product and harvesting satisfied with the 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 there is 1 unqualified, it is unqualified.

h-beam steel compared to ordinary steel is more representative, not only because of its special appearance and similar to the design of the letter H, but also lies in the product's unique performance and personalized parameters, so it can be in many parts of the apparatus or some special scenes play an irreplaceable role. Then the above editorial example is about the price of h-beam manufacturers of information, have the intention to purchase but for the time being there is no clear plan of friends may be able to gain from it.
