Applications of JIS G3101 SS490 Steel
Architectural and Structural Engineering
High-Rise Buildings: Used in load-bearing structures like core tubes and steel frames, replacing traditional concrete to shorten construction periods and reduce dead weight.
Factories and Stadiums: Fabricates large-span roof trusses, trusses, and support columns, meeting lightweight and high-strength requirements.
Seismic Structures: High ductility makes it the preferred material for buildings in earthquake-prone regions.
Bridge Engineering
Main Girders and Crossbeams: Withstands vehicle loads and wind-induced vibrations, requiring high fatigue strength and resistance to lamellar tearing.
Arch Bridge Structures: Processed into curved components via cold bending, reducing the number of welded joints and enhancing structural integrity.
Temporary Supports: Reusable and dismountable, lowering lifecycle costs.
Mechanical Manufacturing
Heavy Equipment Frames: For mining machinery, cranes, presses, etc., requiring resistance to dynamic loads and impacts.
Transport Machinery Bases: Provides stable support for engines and gearboxes, minimizing vibration transmission.
Bolts and Connectors: Hardness improved through quenching and tempering (hardening + high-temperature tempering) to meet high-strength fastening demands.
Vehicle Manufacturing
Truck Frames: Replaces traditional 16Mn steel, reducing weight by 10%-15% while improving fuel efficiency.
Engineering Vehicle Chassis: Withstands harsh road conditions, resisting gravel impact and torsional deformation.
Trailer Structures: Enhances load capacity and stability through optimized cross-sectional designs.
Shipbuilding
Hull Structures: Used in decks, bulkheads, and keels, requiring CCS (China Classification Society) certification to meet seawater corrosion resistance standards.
Offshore Platforms: Deployed in tidal and splash zones, requiring anti-corrosion coatings or cathodic protection technologies.
