•Flexible in design, allowing for creative architectural solutions.
•Applications:
•Exhibition halls
•Atriums
•Dome roofs
5. Steel Arch Structures
Arch structures made of steel are valued for their strength and elegance. They provide efficient load distribution and are often used in projects where aesthetics and durability are equally important.
•Key Features:
•Strong resistance to compressive forces.
•Adds a distinctive architectural appeal.
•Can span large distances with minimal material use.
•Applications:
•Bridges
•Tunnels
•Iconic architectural landmarks
6. Steel Cable Structures
Steel cable structures use tensioned cables to support loads. These structures are highly flexible and lightweight, making them ideal for innovative designs.
•Key Features:
•High tensile strength.
•Provides a sleek, modern look.
•Requires precise engineering and installation.
•Applications:
•Suspension bridges

Steel shell structures are thin, curved plates used to enclose spaces. They are known for their ability to handle complex geometries and distribute loads effectively.
•Key Features:
•Highly efficient in material usage.
•Aesthetic and functional for specialized applications.
•Can achieve a wide variety of shapes and forms.
•Applications:
•Storage tanks
•Silos
•Architectural pavilions
8. Steel Plate Structures
Steel plate structures are formed by welding or bolting together flat steel plates. These structures are often used in situations that require robust, durable solutions.
•Key Features:
•High resistance to external forces.
•Ideal for heavy-duty applications.
•Easy to fabricate and install.
•Applications:
•Ships and marine vessels
•Industrial equipment housing
•Heavy machinery supports
9. Modular Steel Structures
Modular steel structures consist of pre-assembled modules that are transported to the site and combined to form a complete building. This approach is highly efficient and sustainable.
•Key Features:
•Scalable and flexible in design.
•Quick assembly and disassembly.
•Reduces on-site construction time and labour.
•Applications:
•Temporary shelters
•Prefabricated homes
•Portable office spaces
10. Steel Bridge Structures
Steel bridges are engineered to withstand high loads and harsh environmental conditions. They are classified into various types, including beam bridges, arch bridges, and suspension bridges.
•Key Features:
