H-beam steel size
H-beam is a cross-section rolled steel with two parallel flanges of equal thickness and no taper on the inner surface. It is classified into narrow, medium and wide according to the height and flange width.
There are many standards for H-beam, such as Japanese standard（JIS), European standard(EN), American standard(ASTM), etc. Among them, Japanese standard H-beam grades include: SS400, SM490A, SM490B, SN400A, SN400B, SN490B and other steels.
（1）H-beam steel structure components:
Beams and girders: JIS H-beams are commonly used as horizontal support members in buildings, bridges, and industrial structures. They provide strength and stability and can effectively support heavy loads over long spans.
Columns and piles: Vertical support structures in multi-story buildings, warehouses, and other large structures often use JIS H-beams due to their high load-bearing capacity and resistance to buckling.
Frames: These beams are integral to creating the skeletons of various structures, including commercial buildings, factories, and residential complexes. They ensure that the frames are strong and stable and can withstand tremendous forces.
（2）H-Beam Steel Specific Applications:
Bridge Steel Plates: JIS H-Beams are essential in the construction of small and large bridges, providing critical support and stability for vehicular and pedestrian traffic.
Industrial Buildings: Factories, warehouses and large storage facilities benefit from the use of JIS H-Beams in their frames, providing durability and the ability to accommodate heavy machinery and equipment.
Residential Buildings: In multi-story residential buildings, JIS H-Beams ensure structural integrity and safety, making them a top choice for builders seeking long-lasting, durable and resilient structures.
Infrastructure Projects: They are also used in the construction of various infrastructure projects, such as tunnels and highway overpasses, where their strength and reliability are critical.
（3）H-beam Key Features:
Steel Strength and Durability: JIS H-beams are designed to withstand heavy loads and provide long-term durability, which is essential for the stability of large structures.
Steel Versatility: They can be used in a wide range of applications from residential to industrial and infrastructure projects, making them a versatile choice for builders.
Cost-Effective Profiles: Despite their high strength, JIS H-beams offer a cost-effective solution for creating strong and reliable structures, reducing overall construction costs.
Easy Installation: The standardized size and shape of JIS H-beams facilitate easy and quick installation, helping to shorten construction time and reduce labor costs.
