Application of JIS G3106 SM490C Hot Rolled Carbon Steel Sheet
JIS G3106 SM490C is a high-strength structural steel plate with excellent weldability, toughness and impact resistance, especially under low temperature conditions.
Due to its stable mechanical properties and controlled chemical composition, SM490C is widely used in heavy-duty structural and engineering applications where both strength and durability are required.
Typical Applications Include:
Steel Building Structures
Used for beams, columns, trusses, and steel frames in industrial plants, warehouses, and commercial buildings.
Its high load-bearing performance helps improve structural safety and reduce steel usage.
Bridge Construction
Suitable for highway bridges, railway bridges and overpasses where resistance to dynamic load and fatigue is essential.
SM490C's toughness ensures reliable performance under long-term vibration.
Highway & Transportation Infrastructure
Used in overpass supports, steel box girders, guardrails, and tunnel reinforcements.
Its good welding property ensures stable assembly and on-site construction efficiency.
Shipbuilding & Marine Structures
Applied to hull stiffeners, deck frames, support beams, offshore platforms, and port structures, where corrosion resistance and structural stability are required.
Construction Machinery & Heavy Equipment
Used in crane booms, excavator frames, loader arms, and lifting platforms that operate under repeated stress and shock loading.
Pressure Vessels & Storage Tanks
Suitable for manufacturing medium-pressure containers, tank supports, and welded structural components requiring reliable impact strength.
