5 Reasons Why Rebar Is Essential For Construction
The construction industry has been using rebar for hundreds of years. Rebar is also known as reinforcing bars used to support concrete structures. Before it is used in construction, the constructors need to have astute knowledge about cutting rebar and installing it.
Though rebar is essential components of all construction projects, many contractors aren’t fully aware of the various advantages. Before using rebar in construction, every contractor must be aware of these five reasons that make rebar essential for construction.
1. They Support Concrete Structures
The primary reason rebar is used in construction is that they offer exceptional support to various construction structures. They can be used for strengthening bases, columns, foundations, and wall panels.
Multiple rebar is connected with the help of sturdy wires to create a durable mesh structure. These mesh-like structures are submerged in concrete to support the construction. It gives the construction much-needed stability and strength.
The rebar design plays a crucial role in the strength of the construction. The patterns and textures on the rebar provide the essential grip for the concrete. The concrete adheres to the patterns firmly while it dries. Once the concrete settles, the rebar makes the structure capable of withstanding external stresses and pressure.
2. It Offers Greater Ductility
Ductility is one of the major aspects of different construction materials, especially metals. Ductility is the quality of metal that makes it capable of undergoing deformation in different shapes without breaking. Rebar offers higher ductility that is missing in the concrete.
Due to its low ductility, concrete alone cannot support the structure. The concrete is prone to damage and cracks due to its brittleness. The concrete structure often suffers more damage due to natural elements like heat, rain, and snow.
The moisture present in the air bubble in concrete can break down the whole structure. The ductility of rebar makes the concrete resistant to bends and compression that often break the concrete structure. Its ductility has also proven beneficial while cutting rebar as it allows it to be cut in longer lengths without breaking.
3. They Are Easy To Assemble
The ease of assembly makes steel rebar the first choice of contractors. It can be easily installed into different structures like pavings, columns, foundation slabs, and drainages.
Rebar installation involves two methods- tying and welding. The contractor must ensure that the rebar they use is suitable for any of these two stages. For example, if the contractor decides to go with the welding method for assembling the rebar, the rebar must be labeled with a “W” mark. It ensures that the rebar is suitable for welding with other rebar.
From these two methods, tying is preferred for assembling the rebar. The materials required for tying are readily available on construction sites. That means the work can be done faster with minimum materials and less hassle.
4. It Makes The Structure Impact-Resistant
The structure must sustain itself against any impact that can affect its appearance and its strength. Along with other durable materials, steel rebar makes the structure resistant to any impacts.
The strength of the rebar is often tested in natural disasters. Natural calamities like floods and earthquakes can severely damage the concrete structure. The rebar frames make the concrete structure strong enough to resist the impact of rapidly flowing water as well as earthquake shocks. The rebar protects the structures by distributing the impact into different parts of the structure to absorb it easily.
5. It Is Recyclable
According to a survey, 95% of the rebar is made from recycled material. That means it not only strengthens your structure but saves you a lot of money. The rebar is recycled multiple times without losing their strength and elasticity.
As rebar strengthens the concrete structures, choosing the right rebar for your construction is essential. It’s also important to pay close attention while cutting rebar as it affects its assembly. Make sure you choose only top-quality rebar to make your construction last for decades.
