Difference Between S355JR HEA and HEB
S355JR H-beams are classified into HEA, HEB, and HEM types based on thickness and load-bearing capacity. HEA is a light H-beam with flanges and lower weight, suitable for structures with moderate load requirements.
HEB is a standard H-beam with thicker, offering higher load-bearing capacity, making it ideal for medium to heavy buildings and industrial structures. HEA is more economical for transportation and installation, while HEB provides greater strength and structural safety.
Application Examples of HEA and HEB S355JR H Beam
S355JR HEA: In residential building projects or small industrial factories, we typically use S355JR HEA beams for light to medium steel structures. For example, a mid-sized warehouse project may require around 120–150 tons of HEA beams. Due to their lighter weight, these beams are easier to transport and install, making them ideal for projects with moderate load requirements.
S355JR HEB: For large-scale commercial buildings, heavy industrial facilities, or major bridge constructions, we use S355JR HEB beams. In a large bridge project or a high-capacity crane structure, a single project may require 300–500 tons of HEB beams. Their thicker flanges allow for greater load-bearing capacity, ensuring the safety and stability of heavy-duty structures.

What is a steel grade S355JR equivalent to?
S355JR equivalent grades have very close chemical composition and mechanical properties to that of S355JR steel. Both the S355JR equivalent grades Q345B, A572 Gr 50, ST52-3, SM490B and S355JR steel are main products of Gnee steel.
Is S355 equivalent to A36?
S355JR and A36 are not directly equivalent, as S355JR has higher strength (yield 355 MPa vs. A36's 250 MPa) and guaranteed impact toughness, making it closer to ASTM A572 Grade 50 than A36. A36 is often equivalent to S235JR (yield 235 MPa), a lower EN grade.
What is steel grade S355JR?
Steel grade S355JR is used to manufacture hot-rolled flat and long products, which are subsequently used when producing steel building structures. Classification: Non-alloy structural steel. Products: Flat and long products, semi-finished products.
