H-section steel is a kind of economic section high-efficiency profile with more optimized section area distribution and more reasonable strength-weight ratio. It is named because its section is the same as the English letter "H". Because H-beam is arranged at right angles in all parts, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
What is H-beam?
Scope of application of H-beam
H-section steel is mainly used for beam and column members in industrial and civil structures.
Steel Structural Bearing Brackets for Industrial Buildings
Steel Pile and Supporting Structure of Underground Engineering
Structure of Industrial Equipment such as Petrochemical Industry and Electric Power
Members of Long Span Steel Bridge
Ship and Machinery Manufacturing Frame Structures
Railway, automobile, tractor girder bracket
Port conveyor belt, high-speed baffle bracket
H-section steel is a kind of economical section steel, which is widely used in industry, construction, bridge, oil drilling platform and so on.
Introduction of H-beam
H-beams are divided into hot-rolled H-beams and welded H-beams. Hot-rolled H-beams are divided into wide flange H-beams (HW) medium flange H-beams (HM) and narrow flange H-beams (HN).
HW is basically the same height and flange width of H-section steel; it is mainly used for steel core columns in reinforced concrete frame structure columns, also known as stiff steel columns; it is mainly used for columns in steel structure.
The ratio of H-beam height to flange width is approximately 1.33~1.75 in steel structure: steel frame columns are used as frame beams in frame structures subjected to dynamic loads; for example, equipment platforms.
HN is H-beam whose ratio of height to flange width is greater than or equal to 2. It is mainly used for beams, and I-beam is equivalent to HN-beam.
The main materials of H-section steel are Q235B, SM490, SS400, Q345, Q345B, etc.
H-section steel is a new type of economic construction steel. Compared with common I-section steel, H-section steel has the advantages of large section modulus, light weight and metal saving, which can reduce the building structure by 30-40%. Because of its parallel inner and outer legs and right angle at the end of legs, assembling and assembling components can save the workload of welding and riveting up to 25%. It is often used in large-scale buildings (such as factory buildings, high-rise buildings, etc.) requiring large bearing capacity and good cross-section stability, as well as bridges, ships, lifting and transportation machinery, equipment foundations, brackets, foundation piles, etc.
H-section steel is a kind of economical section steel with better cross-section mechanical properties, which is developed by optimizing I-section steel. Especially, the cross-section is named after the same as the English letter "H". Its characteristics are as follows:
Wide flange, large lateral stiffness. The bending resistance is strong, about 5% - 10% higher than I-beam.
The flange surfaces are parallel to each other, which makes the connection, processing and installation easy.
Compared with welded I-beam steel, it has low cost, high precision, low residual stress, no expensive welding materials and weld detection, and saves about 30% of the manufacturing cost of steel structure.
Under the same section load, the weight of hot rolled H steel structure is reduced by 15% - 20% compared with traditional steel structure.
Compared with concrete structure, hot-rolled H-steel structure can increase the area of use by 6%, reduce the weight of structure by 20% to 30%, and reduce the internal force of structure design.
H-section steel can be processed into T-section steel, and honeycomb beams can be combined to form various cross-section forms, which greatly meets the needs of engineering design and production.
