The steel structure is a structure which is made from the organized combination of custom-designed structural steel members to meet architecture and engineering requirements of users. Steel structure involves sub-structure or members in a building made from structural steel.

Various shapes of structural steel

• I-Beam
• Z-Shape
• Hollow structural
• Angle: L-shaped cross-section
• Structural Channels: C-beam or C-shaped cross-section
• T-shaped cross-section
• Rail Profile: Strap rail, Flanged rail, Baulk rail, Barlow rail, Flat bottomed rail, Double-headed rail, Bullhead rail, Tangential turnouts, Grooved rail
• Bar: a piece of metal, rectangular cross-sectioned and long, but not so wide to be called a sheet.
• Rod
• Plate
• Open web joists

Above mentioned shapes are used while constructing steel structures.

Main structural types

• Truss structures
• Frame structures
• Grids structures
• Arch
• Prestressed structures
• Beam bridge
• Truss bridge
• Arch bridge
• Cable-stayed bridge
• Suspension bridge

Advantages of steel structure

1- Cost savings

2- Quick erection

3- Health and Safety

4- Flexibility

Disadvantages of steel structure

1- The maintenance cost of a steel structure is very high.

2- Steel has very small resistance against fire as compared to concrete.

3- Steel cannot be mould in any direction you want.

4- steel loses its ductility property than chances of brittle fractures increase.
