Information on Reinforcement steel works at construction Project
In any construction project which includes building of reinforce concrete structures, Reinforcement steel works is a very important activity and it directly impact on durability of the structure built with it.

In attached document on reinforcement steel, i had included every possible details which is required for execution of any RCC structure, the content of document is as follows;
Category of Reinforcements
Carbon steel bars (plain and deformed).
Cold reduced plain and deformed steel wire fabric.
Stainless steel bars and fabric.
Galvanized carbon steel bars and fabric.
Epoxy coated carbon steel bars.
Fiber Reinforced Polymer (FRP) rebar- [Non steel reinforcement]
