H-shaped steel is an economical and efficient section 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". Since all parts of H-beam are arranged
at right angles, H-beam has been widely used for its advantages of
strong bending resistance, simple construction, cost saving and
light structural weight in all directions.Its characteristics are
as follows:
1. Wide flange and large lateral stiffness.
2. Strong bending resistance, about 5% - 10% higher than I-beam.
3. The two surfaces of the flange are parallel to each other,
making the connection, processing and installation simple.
4. Compared with welded I-beam, it has the advantages of low cost,
high accuracy, low residual stress, no need for expensive welding
materials and weld detection, and can save about 30% of steel
structure manufacturing cost.
5. Under the same section load, the weight of hot-rolled H steel
structure is 15% - 20% less than that of traditional steel
structure.
6. Compared with the concrete structure, the hot-rolled H steel
structure can increase the service area by 6%, while the dead
weight of the structure can be reduced by 20% - 30%, reducing the
design internal force of
the structure.
the structure.
7. H-shaped steel can be processed into T-shaped steel, and
honeycomb beam can be combined to form various cross sections,
which greatly meets the requirements of engineering design and
production.
