Applications of GB/T 700 Q235A Steel
Building and Structural Engineering
Load-bearing components (e.g., steel beams, columns, roof trusses): Leverages its high strength and plasticity to form the skeletal structure of factories, warehouses, and other buildings.
Reinforcing bars in reinforced concrete structures: Enhances the tensile properties of concrete, extending building lifespan.
Mechanical Manufacturing Industry
Non-critical mechanical parts (e.g., bolts, nuts, tie rods, sleeves, brackets): Utilizes its ease of processing and cost advantages.
Small machine housings and equipment bases: Replaces more expensive alloy steels in low-stress applications, reducing manufacturing costs.
Bridges and Transportation Infrastructure
Bridge structural components (e.g., connection plates, support frames): Its toughness minimizes fatigue crack propagation under dynamic vehicle loads.
High-voltage transmission towers: Combines high strength and weather resistance to ensure stability in harsh environments.
Marine and Pressure Vessels (Non-critical Components)
Small hull structural parts (e.g., deck supports, bulkhead connectors): Reliable performance in non-arctic maritime conditions.
Low-pressure storage tanks and pipe supports: Suitable for non-critical containers with modest toughness requirements, such as auxiliary LPG storage tanks.
Daily Life Products
Metal furniture frames (e.g., office desks, shelving): Benefits from its moldability and cost efficiency.
Simple metal tools (e.g., manual punches, mold handles): Surface hardness and service life can be improved through quenching treatments.
