Uses: Steel is environment-friendly & sustainable. It posses great durability. Compared to other materials, steel requires a low amount of energy to produce lightweight steel construction.  Steel is the world’s most recycled material which can be recycled very easily. Its unique magnetic properties make it an easy material to recover from stream to be recycled. Steel can be designed in various forms. It gives better shape and edge than iron which is used to make weapons.   Engineering steels are used for general engineering and manufacturing sectors.   Steel is highly used in the automobile industry. Different types of steels are used in a car body, doors, engine, suspension, and interior. The average 50% of a car is made of steel.  Steel reduces CO 2  emissions.  All types of energy sectors demand steel for infrastructure and resource extraction.   Stainless steels are used to produce offshore platforms and pipelines.   St...

TYPES OF ROLLED STRUCTURAL STEEL SECTIONS: Mostly for the design of steel structures rolled structural steel adopted and  The various types of rolled structural steel sections manufactured and used as structural members are as follows as  per BIS : ( IS: 808-1989 ) : ( Based on the size and weight of the sections again classified as light, medium, high sections.....Let's see an example ISMB means Indian standard Medium beam and ISLC means Indian Standard Light channel like........) (THE CODE WILL TELLS ABOUT THE DIMENSIONS FOR HOT ROLLED STEEL SECTIONS) Rolled Steel I-sections (Beam sections). Rolled Steel Channel Sections. Rolled Steel Tee Sections. Rolled Steel Angles Sections. Rolled Steel Bars. Rolled Steel Tubes. Rolled Steel Flats. Rolled Steel Sheets and Strips. Rolled Steel Plates CLICK HERE TO SEE  IS 808 1989 PDF

1. Steel is a term given to alloys containing a high proportion of iron with some carbon. Other alloying elements may also be present in varying proportions.  2. The properties of steel are highly dependent on the proportions of alloying elements so that their levels are closely controlled during its manufacture. 3.  The properties of steel also depend on the heat treatment of the metal. Steel is by far the most important metal, in tonnage terms, in the modern world, with the annual global production of over 700 million tonnes dwarfing the approximately 17 million tonnes of the next most prolific, aluminum.  4. The low price and high strength of steel mean that it is used structurally in many buildings and as sheet steel, it is the major component of motor vehicles and domestic appliances.  5. The major disadvantage of steel is that it will oxidize under moist conditions to form rust.

ADVANTAGES OF STEEL DESIGN  1. Better quality control  2. Lighter  3. Faster to erect  4. Reduced site time – Fast track construction  5. Large column-free space and amenable for alteration  6. Less material Handling at site  7. Less percentage of floor area occupied by structural elements  8. Has better ductility and hence superior lateral load behavior, better earthquake performance  DISADVANTAGES OF STEEL DESIGN  1. Skilled labor is required  2. The higher cost of construction  3. Maintenance cost is high (Due to corrosion)  4. Poor fireproofing as at 1000o F (538oC) 65% and at 1600o F (871oC) 15% of strength remains  5. Electricity may be required (to hold joints, etc.)
