INTRODUCTION 

MAN MADE METAL DERIVED FROM IRON- WHICH IS ITS MAJOR CONSTITUENT.



STRUCTURAL STEEL IS A CATEGORY OF STEEL USED AS A CONSTRUCTION MATERIAL FOR MAKING STRUCTURAL STEEL SHAPES.



A STRUCTURAL STEEL SHAPE IS A PROFILE, FORMED WITH A SPECIFIC CROSS SECTION AND FOLLOWING INDIAN STANDARDS



STRUCTURAL STEEL SHAPES, SIZES, COMPOSITION, STRENGTHS, STORAGE PRACTICES, ETC. ARE REGULATED BY STANDARDS OF THE RESPECTIVE COUNTRIES.
