What Is Rebar Size and Rebar Diamters?
The Rebars are steel reinforcement bars that are used with concrete to improve the tensile strength of concrete. Because, it is a known fact that concrete is very weak in handling tension force, but is strong in handling concrete forces which are acting on any structure.
There are various Reabr Size and Rebar Diameter Used in construction as per work and conditions.
Steel is the only material used as Rebar in concrete because its elongation at high temperature is nearly the same as that of concrete.
Types of Rebars
1. Carbon Steel Rebars
The carbon steel rebars are the most commonly used steel bars used in construction and it is sometimes also called “Black Rebar”. But, one of the biggest drawbacks of this rebar is that it is easily catching corrosion compared to other types of rebar.
Therefore, It is not used in an area that is subjected to high humidity and in a structure that is continuously in contact with water.
But, It is one of the best rebars to be used in construction other than water contact.
2. Welded Wire Fabric
It is manufactured by electrically welding a series of steel wires arranged at a right angle. It is mostly used for ground-level slabs where the ground is properly compacted and leveled.
These types of rebars are used for box culverts, road pavement, drainage structures, and small concrete canal construction work.
3. Sheet-Metal Reinforcing Bars
It is manufactured from annealed sheet steel pieces and bent in corrugated shape with 1/6 inch deep holes punched at a specified distance.
These bears are mainly used for roof construction, floor slab, and stairs formation work.
4. Epoxy-Coated Rebars
Expoxy Coated Rebars is one of the expensive types of rebars that are used in an area where the structure keeps continuous contact with seawater and high humidity area.
It coating must be done properly for the best result otherwise it is also liable to corrosion.
5. European Rebars
The European Steel Rebars are generally manufactured from manganese mineral material which is having the property of easily bending.
These types of rebars are not suggested to be used in extreme weather conditions such as earthquake-prone zones, hurricanes, and rainstorms areas.
6. Stainless Steel Rebars
Stainless steel rebars are used as alternative rebar with carbon steel reinforcement bars. Stainless steel rebars are corrosion resistance coating on it which is the best option in an area that has corrosion problems.
But, Its cost is nearly eight times the cost of carbon steel rebars.
7. Galvanized Rebars
These rebars are most suitable for making strong structures that are supposed to expose in an area of high humid conditions. Galvanized Rebars are 40 times more corrosion resistant compared to normal carbon steel rebars.
