1.4404 stainless steel, also known as AISI 316L, is a low-carbon version of 316 stainless steel, known for its excellent corrosion resistance and mechanical properties. The following is an overview of its application in civil engineering structural profiles:

Buildings and Building Structures Exterior Walls and Cladding: Used on building exteriors to provide aesthetics and weather resistance to enhance durability and appearance.
Railings and Handrails: Used on stairs, balconies and walkways to provide security and a modern look.

Bridges and Intersections Structural components: Used in bridge construction of beams, beams and trusses, which benefit from its strength and corrosion resistance, especially in coastal areas.
Expansion Joints: Effective in expansion joints in bridges that require movement, maintaining structural integrity.

Marine Structures Docks and Docks: Ideal for marine applications due to its resistance to salt water corrosion, making it suitable for docks and docks.
Offshore Platform: For offshore structures generally exposed to harsh marine environments.

Infrastructure Project Tunnels and Underground Structures: Used in tunnel linings and support structures with durability against moisture and chemical resistance.
Water Treatment Facilities: Used in water tanks, pipes and structural supports due to its resistance to chemicals and water corrosion.

Industrial Building Framing and Bracing: Used in the construction of industrial facilities, including warehouses and manufacturing plants, where strength and corrosion resistance are critical.
Storage Tanks: Storage tanks used in manufacturing chemicals and other materials to ensure safety and longevity.

1. Corrosion resistance: Excellent resistance to pitting and crevice corrosion, especially in chloride environments, making it ideal for a variety of applications.
2. Mechanical properties: high tensile strength, good ductility, and can achieve a variety of structural designs.
3. Aesthetics: Attractive finishes can enhance the visual appearance of a structure and usually require minimal maintenance.

Cost: Although more expensive than carbon steel, the long-term benefits of reduced maintenance and increased service life often justify the investment.
Welding and Fabrication: Specific welding techniques and precautions are required to avoid problems such as sensitization and corrosion at the weld.
