EN S355J2 HEA HEB H Type Steel Beam

HEA HEB belongs to the European standard wide flange beam family, featuring an "H" shaped cross section and made from high-strength low-alloy structural steel S355J2 steel, which has excellent mechanical properties and is suitable for a wide range of structural applications.

Key properties of S355J2 h type steel beam include:
Minimum yield strength: 355 N/mm² (thickness ≤ 16 mm).
Tensile strength: Typically ranges from 470 to 630 N/mm², depending on thickness.
Impact toughness: "J2" means tested to withstand a minimum impact energy of 27 Joules at -20°C, ensuring good performance in cold environments.
Chemical composition: Mainly composed of carbon (C ≤ 0.20%), manganese (Mn ≤ 1.60%), silicon (Si ≤ 0.55%), phosphorus (P ≤ 0.025%) and sulfur (S ≤ 0.025%), and contains trace amounts of other elements to enhance its properties.

HEA (High Edge A) and HEB (High Edge B) are two European standard H-type steel beams characterized by their flange and web ratios, both are hot rolled steel profiles with parallel flanges, which can provide efficient load-bearing capacity.

S355J2 HEA HEB h type beam is produced by a hot rolling process, where the steel billet is heated and passed through rollers to form an H-shaped cross-section, which can ensure uniformity, strength and precise dimensions, and post-rolling treatments such as normalizing or quenching can be applied to further enhance the properties of the steel.

HEA steel beam h
Lightweight design: Compared with HEB beams, HEA beams are lighter, with thinner flanges and webs relative to their height.
Flange to Web Ratio: Wider and thinner flanges provide a balance between strength and flexibility.
Applications: For structures that need to reduce weight without sacrificing important structural integrity, such as residential buildings, roof frames, and lightweight bridges.

HEB Beams
Strong Design: HEB beams are heavier and stronger with thicker and wider flanges than HEA beams of the same height.
Flange to Web Ratio: The increased thickness provides greater load-bearing capacity and resistance to bending.
Applications: Ideal for heavy-duty applications such as industrial buildings, long-span bridges, and highly loaded structural frames.

Applications of S355J2 HEA HEB Beams
Construction: For columns, beams, and braces in commercial and residential buildings, warehouses, and stadiums.
Infrastructure: For bridges, tunnels, and railway structures to increase their load-bearing capacity.
Industrial: For heavy machinery frames, crane structures, and offshore platforms.
Architecture: For frames with aesthetically pleasing designs.
