S355J2 HEB550 HEA550 Wide Flange H Beam

HEB550 and HEA550 structural steel h beams made of S355J2 material have excellent material properties and reasonable cross-sectional shape. They are very suitable for use in many engineering fields such as construction, bridges, and machinery manufacturing. They can meet the requirements of various different projects for steel strength, toughness, stability, and processing performance.

Chemical composition: Carbon (C) ≤ 0.22% (some standards have an upper limit of 0.24%), Manganese (Mn) ≤ 1.60%, Silicon (Si) ≤ 0.55%, Phosphorus (P) and Sulfur (S) ≤ 0.025%, Copper (Cu) ≤ 0.55%, Chromium (Cr) ≤ 0.30%, Nickel (Ni) ≤ 0.50%.

Mechanical properties: The minimum yield strength is 355MPa, the tensile strength is usually between 470-630MPa, and the elongation after fracture is ≥ 18%. It can still maintain excellent impact toughness at - 20℃ low temperature environment, and the impact energy (Aku) is ≥ 27J.

Processing performance: By adding appropriate alloy elements and strictly controlling carbon, the material has good cutting, bending, drilling, milling and other processing properties while maintaining good weldability.

Dimensions: height 550mm, width 300mm, web thickness 15mm, flange thickness 29mm, weight per meter is about 199kg/m.

Performance characteristics: Due to the H-shaped cross-section, there is a large bearing area, so the bearing capacity is strong and can withstand large loads; good stability, stable cross-section shape, not easy to deform, can maintain long-term stable bearing capacity; convenient processing, size and shape meet the standard requirements, easy to process and manufacture, can meet various application requirements.

Application field: suitable for various large I-beams, large-span trusses, frame structures, seismic support structures and other engineering fields, especially high-rise buildings, large-span bridges, super high-rise buildings and other projects with high requirements for steel strength and stability.

Dimensions: HEA550 steel is a wide flange H-beam steel, with specific dimensions of 550mm in height, 250mm in flange width, 10mm in web thickness, 17mm in flange thickness, and a weight of about 105kg/m per meter.

Performance characteristics: It has high strength and rigidity and can withstand large loads and pressures. Its flange is wide, and it performs better when subjected to bending moment and shear force, and can provide good support and stability for the structure.

Application areas: It is commonly used in beam and column components in building structures, such as structural support for large factories, commercial buildings, industrial facilities, etc. It can also be used in some occasions that have certain requirements for structural weight, but at the same time require higher strength and stability, such as the superstructure of bridges and the support structure of offshore platforms.
