- 1. DETAIL OF STEEL SECTIONS USED IN PAKISTAN Submitted by# KAMRAN(19L-2603)
- 2. SUMMARY INTODUCTION CLASSFICATION PAKISTAN STEEL STRUCTURE STEEL STRUCTURE USED AND MANUFACTURED IN PAKISTAN
- 3. Introduction to Steel Steel is nothing but it is a modified form of an Iron, Because when we add o.o2 to 1.7% of Carbon and some other material such as Silicon, Nickel, Manganese and Copper to Iron during its manufacturing then we call it Alloy or Steel
- 4. Classification of Steel: Name of Steel Carbon Content in Steel Very Low Carbon Steel <0.1% Mild Steel Up to 0.25% Medium Carbon Steel 0.25-0.7% High Carbon Steel 0.7%-1.5%
- 5. Introduction to Structure A structure is a series of connected elements that form together a system that can resist a series of external load effects applied to it, which includes its own self weight, and provide adequate rigidity. In civil engineering, a structure is usually made up of Beams Columns Cables Slabs etc

- 8. SHAPES OF STRUCTURAL STEEL USED IN PAKISTAN The cross sectional properties of a steel member are identified by its shape. The various names given to the members of different shapes are Angles ; T- section; Isection; Z-section; Channel; H-section….and so on . Each shape has its particular use in steel structures
- 9. SHAPES OF STRUCTURAL STEE BARS
- 10. BARS Used as ties and lateral bindings. If threaded at the ends or looped at end,used as tension members. Types according to manufacturing process: 1. Cold Rolled Steel Bar 2. Hot Rolled Steel Bar 3. Galvanized Steel Bar Types according to shapes: 1. Round bars 2. Square bars 3. Hexagonal bars 4. Flat bars
- 11. ANGLE SECTIONS
- 12. ANGLE SECTIONS Used especially in the construction of steel roof trusses and filler joist floors. May be of equal or unequal legs.
- 13. CHANNELS
- 14. CHANNELS Used as structural members of steel-framed structures. Consists of web with two equal flanges.
- 15. T-SECTIONS
- 16. T-SECIONS Widely used as members of steel roof trusses and to form built up sections. It is designated by overall dimension and thickness.
- 17. I-SECTIONS
- 18. I-SECTIONS These are properly known as the rolled steel joists or beams. It consist of two flanges connected by a web. I-sections are used in beams and columns. It is best suited to resist bending moment and shearing force
- 19. STEEL TUBES
- 20. STEEL TUBES The steel tubes are used as columns and compression members and in some cases it also acts as a tension member in tubular trusses. The steel tubes are efficient structural sections to be used as compressive members. Steel tube sections have equal radius of gyration in all directions.
