S355JR H-section steel is a hot-rolled H-section steel made of S355JR. The name comes from the European standard EN 10025-2. In the Chinese standard, it is approximately equivalent to Q345B. "S" stands for structural steel, "355" means the minimum yield strength is 355MPa, and "JR" means the impact test temperature is 20℃, and there are certain impact energy requirements.

Mechanical properties of S355JR h section steel
Yield strength: ≥355MPa when thickness ≤16mm; the yield strength decreases slightly with the increase of thickness, and the yield strength is 345MPa when 16mm<thickness ≤40mm.
Tensile strength: 470-630MPa
Elongation: ≥22%
Impact energy: At 20℃, the minimum absorbed energy is 27J.

Advantages of S355JR h-shaped steel
High strength: It has a high yield strength of more than 355MPa, which enables the structure to withstand large loads and is suitable for projects with high strength requirements such as large-span bridges and high-rise buildings.
Good toughness: It exhibits good toughness at room temperature and has good resistance to brittle fracture, which can ensure the safety of the structure under dynamic loads and various complex working conditions.
Good weldability: It has a low carbon equivalent and good weldability. It can be easily and reliably welded with other steel components, reducing the risk of welding cracks and improving construction efficiency and quality.
Good processability: It can be easily processed by cutting, drilling, bending and other processes, which can meet the needs of different shapes and sizes in engineering design and is easy to construct and install.

Types and sizes of S355JR h beam structure
Wide flange H-beam (HEA, HEB): such as HEA100, the dimensions are 96mm in height, 100mm in width, 5mm in web thickness, 8mm in flange thickness, 21.24cm² in cross-sectional area, 72.76cm³ in cross-sectional modulus, and 16.7kg/m in weight.
Narrow flange H-beam (IPE): such as IPE100, the dimensions are 100mm in height, 55mm in width, 4.5mm in web thickness, and 7.1mm in flange thickness.

Application areas of S355JR h section beam
Construction industry: widely used in industrial and civil construction, such as columns and beams in factories, steel structures of high-rise buildings, and can also be used as steel piles and supporting structures in underground projects.
Bridge engineering: can withstand large vertical and horizontal loads during the use of bridges to ensure the safety and stability of bridge structures.
Machinery manufacturing: used in the frame structure of mechanical equipment, such as the beam bracket of large mechanical equipment, etc., which can provide stable support and ensure the normal operation of the equipment.
