S355JR / S355J2 High Strength Structural Steel Coil

S355JR and S355J2 are premium high‑strength structural hot‑rolled steel coils conforming to EN 10025‑2 standard. With minimum 355MPa yield strength, they deliver superior structural rigidity. S355JR provides stable room‑temperature toughness, whereas S355J2 features excellent‑20℃ low‑temperature impact performance for harsh‑climate heavy‑load engineering. They are preferred raw materials for wind power parts, bridge structures and heavy‑duty equipment.
