When steel bars are combined with plain cement concrete the result will be steel reinforcement concrete. These structures form steel reinforced cement concrete structure (r. C. C.) Which are called by the name ‘rebars’. These rebars expand the elasticity of the structure as time elapses. Rebar’s surface is regularly deformed with ribs, spaces to advance a superior bond with the solid concrete and diminish the danger of slippage.
There are so many types in steel reinforcements. Through this blog we will be discussing the types in steel reinforcement one by one,
1. Hot rolled deformed steel bars
These are the most widely used reinforcement for a regular rcc structures. Most of the structures make use of hot rolled reformed steel bars for more strength and durability. Deformations are given on the surface of steel in the factories so that it can bond with the concrete very easily. Because of easy bonding nature with the concrete these type of steel bars are commonly used for most of the rcc structures.
2. Cold worked steel bars
When hot moved steel bars are allowed to cool down in a special process, cold worked steel bars are formed. In this entire process steel bars will undergo twisting and drawing which is performed at room temperature. These bars have less flexibility as compared to hot rolled deformed steel bars.
3. Mild steel plain bars
Mild steel plain bars are manufactured under a specific temperature which are used in the construction of reinforced cement concrete slab beams, etc., in rcc work. Typically these bars are plain in surface which are produced in round segments of typically 6 to 50mm diameter. These are made in long lengths and can be cut rapidly into any shape or size without any harm. Mild steel plain rods can be used in the small projects where economy is the real concern.
4. Deformed steel bars
Deformed steel bars have a ribbed surface which are available in three different types of shapes: winding, herringbone and crescent. These steels bars can be directly utilized in strengthened solid structure and can be used as a prestressed strengthening bar after the cold drawing. These deformed steel bars are widely utilized in numerous fields as a development material.
5. Prestressing steel bars
Prestressing steel bars are compromised of numerous standards which are made up of prestressing cables or tendons. These wires are spun together into a strand thus creating a strong and durable prestressing steel bars. As these wires are cold drawn, thus have exceptionally high tensile strength. These are utilized in prestressing solid like rcc braces of scaffolds.
6. Twisted steel bars
These are commonly known as prestressing tendons. When seven different types of wires spun together into a strand, the result is a strong and durable twisted steel bars. These carries high tensile strength upto 270000 psi. Because of high tensile value these type of steel bars are used on braces of scaffolds for prestressing reinforced cement concrete.
7. Welded steel wires
When steel wires are welded into a mesh these type of steel wires are produced. The outcome is of medium tensile strength which are used for partitions, fencing etc. These steel wires can be produced in different diameters whose strength is higher that that of a mild steel bar this is the reason why welded steel wires are accepted widely for particular segments in construction for better efficiency.
Advantages of steel reinforcement :
These are widely used across the globe because of the following advantages associated with it,
1. Compatibility
These have a great compatibility factor with concrete. The fresh concrete is placed on the formwork mold already prepared with reinforcement. The steel reinforcement won’t float in concrete during the concrete placing procedure. Hence, steel reinforcement does not demand special tying up with formworks.
2. Bent property of steel reinforcement
These bars have a great feature of bendability. Once manufactured to standard size, these can be bent to the required specifications thus fabricated steel bars are delivered easily at the desired site.
3. Recycling property
The leftover steel reinforcement can be recycled again and used for new constructions again.
4. Easily available
Steel reinforcements are easily available at any part of the world, as it’s a most demanding material for all the construction needs.
Because of the high tensile strength tmt bars (thermo mechanically treated) are widely accepted worldwide. Tmt bars not only provide strength to the constructions they are also flexible enough to provide certain protection to the structures. During the natural disasters like earthquake, flood etc. Because of these tmt bars structures are protected. They also consist of less amount of carbon because of which tmt bars are less fatigue and highly corrosion resistant as well.
As per is standards fe 500d grade of tmt bar has the perfect combination of strength & flexibility. That is why it is most recommended for construction purpose. Uma TMT bars possess all the above features, this is the reason why our bars are popular and are widely used across Maharashtra and other states of India for all the construction needs.
