Pure Europe Standard Hot Rolled H Beam Steel in Wide Flange Universal Beams UB Universal Columns UC
Hot-rolled H-beam steel has wide flanges and large lateral rigidity; it has strong bending resistance, about 5-10% than I-beam steel. The two flanges are parallel to each other, and the structure is convenient.

Hot-rolled H-beams reasonably distribute the aspect ratio of the section size according to different purposes, and have excellent mechanical properties and superior use performance.
High structural strength. Compared with the I-beam, the section modulus is larger, and the metal can be saved by 10-15% under the same bearing conditions.
The design style is flexible and rich. In the case of the same beam height, the steel structure bay can be 50% larger than the concrete structure bay, thus making the building layout more flexible.
The structure is light. Compared with the concrete structure, it is lighter than the concrete structure, and the structure's own weight is reduced, which reduces the internal force of the structure design, which can make the building structure foundation treatment requirements low, simple construction and lower cost.
The steel structure mainly made of hot-rolled H-section steel has scientific and reasonable structure, good plasticity and flexibility, and high structural stability. It is suitable for building structures that withstand large vibration and impact loads. It has strong resistance to natural disasters, and is especially suitable for many The building structure in the earthquake zone. According to statistics, in the world's devastating earthquake disasters of magnitude 7 or above, steel structures dominated by H-shaped steel have suffered the least damage.
Increase the effective use area of the structure. Compared with the concrete structure, the steel structure column has a small cross-sectional area, which can increase the effective use area of the building. Depending on the different form of the building, it can increase the effective use area by 4-6%.
Compared with welding H-shaped steel, it can significantly save labor and materials, reduce the consumption of raw materials, energy and labor, with low residual stress, and good appearance and surface quality.
It is convenient for machining, structural connection and installation, and easy to dismantle and reuse.
The use of H-section steel can effectively protect the environment, which is reflected in three aspects: first, compared with concrete, dry construction can be used, which produces less noise and less dust; second, due to the lighter weight, the amount of soil taken for foundation construction is less. Land resource damage is small. In addition, a large reduction in the amount of concrete and mountain excavation is beneficial to the protection of the ecological environment; third, after the service life of the building structure expires, the amount of solid waste generated after the structure is demolished is small, and the recycling value of scrap steel resources is high .
The steel structure mainly made of hot-rolled H-beam has a high degree of industrial production, which is convenient for mechanical manufacturing, intensive production, high precision, convenient installation, and easy to ensure quality. It can be built into a real house manufacturing factory, bridge manufacturing factory, industrial factory manufacturing factory, etc. . The development of steel structures has created and promoted the development of hundreds of emerging industries.
The construction speed of the project is fast, the area is small, and it is suitable for all-weather construction, and it is less affected by the weather conditions. The construction speed of the steel structure made of hot-rolled H-section steel is about 2-3 times that of the concrete structure, the capital turnover rate is doubled, and the financial cost is reduced, thereby saving investment. Take the "Jinmao Building" in Pudong, Shanghai, my country's "highest building" as an example. The structural main body with a main body height of nearly 400 m completed the structural roofing in less than half a year, while the steel-concrete structure requires a two-year construction period.
