Why is steel important for building constructions?

Introduction 

Steel is an alloy made up of carbon and iron with a few amount of manganese, silicon, phosphorus, sulphur and oxygen which is helps to improve the strength and resistance. Its durability, strength and flexibility helps to design the buildings and homes effectively.

Types of Building Constructions Steel

TMT Bars

Binding Wire

 1.TMT Steel Bars

TMT bars, it means Thermo-mechanically Treated bars. TMT Bars are high strength bars having rough and tough outer layers or outer core and soft inner layers or inner core.

Various grade Types of TMT steel

Manufacturers commonly maintain a

➤ Fe-415D,Fe-500D,Fe-550D,Fe-600.

 Fe-415D,500D,550D,600, Fe denotes Iron and 415,500,550,600 stands for the minimum yield stress in N/mm2 and the letter D denotes bars that have higher values of ductility. Every grads mainly having a different tensile strength, yield stress and ductility.

Tensile Strength – The resistance of steel to break under tensile tension. The minimum Tensile Strength  is 500 N/mm2 for Fe 415D grade, Fe 500D is 565 N/mm2,Fe 550D is 600 N/mm2 and  Fe 600 is 660 N/mm2.

Yield stress – Transition from elastic to plastic behavior, is the minimum stress at which a solid will undergo permanent deformation without a significant increase in the load or external force. Yield stress for Fe 415D is 415 N/mm2,Fe 500D is 500 N/mm2, Fe 550D is 550 N/mm2 and Fe 600 is 600 N/mm2.

Ductility- it  is the ability of a material to be  plastically deformed without fracture. Ductility for Fe 415D is 14.5%, Fe 500D is 16%, Fe 550D is 18% and Fe 600 is 10%.

Different size of TMT Steel Bars 

TMT Bars come in different diameters like-    

 8mm TMT Bars

10mm TMT Bars

12mm TMT Bars  

16mm TMT Bars 

20mm TMT Bars  

25mm TMT Bars 

32mm TMT Bars 

36mm TMT Bars etc..

 2 . Binding Steel Wire

Binding wire made up of Mild Steel used to binding the rebar junctions or joints in the field of constrictions. Which is helps to keep the structure intact. Which is made up of Mild Steel. The commonly used wire diameter is 0.8 mm, 1 mm and 1.2 mm.

Different size of Binding Wire

Binding Wire comes in different diameters like- 

0.8mm Binding Wire

1mm Binding Wire  

1.2mm Binding Wire etc..

Benefits for using TMT Steel Bars and Binding Wire

8mm-10mm diameter of bars used in slabs and stair ups are according to members.

12mm-25mm diameter of bars used in Beams & Columns are according to External loads.

32mm-36mm diameter of bars used in complex projects like bridges, Dams.

Binding Wire used for hold reinforcing bars with different diameters.

It needs to bind reinforcement slabs, mesh processing, beams, walls, columns and it is used in concrete construction.

Binding wire is using for  ropes, cables, springs and electrodes.

 Binding wire used in various industries for packing finished products.

Conclusion 

Steel provides light weight structure and rapid construction with comparison to concrete. it easily allows alteration and expansion if needed. It is highly durable, dimensionally accurate material produced with modern computerized technology. Steel structure giving a less health hazards, less waste, less Energy usage, less emissions and better Environmental work.
