It is seemingly a very small thing, but it plays a crucial role in the construction. Yes! Binding wire is an indispensable item in construction, yet the facts about it are little known. Before diving into the details of binding wire, let us first know what it is and importance of binding wire!
What is the binding wire? How are they made?
Binding wire is used for tying purposes in the construction industry. It is used primarily for tying rebars right at the joints to keep the entire structure intact and maintain buildings’ integrity. The steel used for making these wires is annealed to become flexible and easily tied.
This steel is known as mild steel, and the wires made from them are MS wires. Binding wires are manufactured and annealed in such a way that they get the required adaptability for their multiple applications and can gain the tensile strength needed for making knots without breakage.
Annealing of MS binding wire makes them supple, which is why they remain unaffected in any weather conditions. These wires help the rebars and secondary frame models like space bars and chairs remain intact during construction.
Binding wire for construction is indispensable as it has multiple usages that cannot be accomplished with other things. Whether it is about binding the reinforcement slabs with metal mesh processing or keeping beams and columns intact, its usage cannot be avoided in any concrete construction.
What should be the right guage?
16-22 gauge is the range of binding wire used in civil construction, and the amount used depends on the material of the binding wire, grade, and surface treatment. The most commonly used binding wire in construction is 18 gauge.
What affects the quality of binding wire?
Different factors that affect the quality of binding wire in construction are spacing between the rebars, their diameter, type, and gauge of binding wire used, and tying ways or methods used (like manually by hooks or mechanically by using rebar tying tools.)
Importance of Binding Wire in Construction
Although the main purpose of binding wire is to tie rebars right at their joints to maintain their integrity, there are several other benefits of binding wire that go unnoticed like:
Apart from tying the reinforcement bars, binding wires are used primarily for creating a metal mesh for constructing beams, columns, walls, and more. Without binding support, wire reinforcement can move freely, and the entire mounting would be flexible. In addition, support space in one portion widens, and the other gets narrower without binding wire. This makes the entire structure unstable and vulnerable to collapse.
Here are the different purposes of wire binding:
- It provides the proper spacing between the reinforcement bars.
- It helps keep the lapped bars closer so that forces can be transferred precisely.
- It keeps bars in place while concrete is poured.
- To keep the secondary structures, like spacer bars, chairs, etc., right in their position during construction.
Also, binding wires are used for different types of construction-related activities, like transportation and grouping, etc.
What makes binding wire suitable for construction?
- The elasticity of these wires allows them to get tied easily without breaking.
- They are annealed, which makes them fragile and easy to use.
- They are used for maintaining the integrity of lapping bars and for keeping them in the proper place.
- Space bars in the building systems are meant to support the secondary frame designs.
- They aid in emptying solids in the margins while minimizing the disruption of reinforcement bars.
Factors determining how much of it should be used
Several elements determine how much binding wire will be used in the construction. Like the following:
- The diameter of the reinforcing bars.
- Spacing of reinforcement bars from each other
- Type and gauge of the binding wire used.
- Which type of wire binding methods and tying methods are used?
- Kind of the structural part.
- Whether it is manual hook tying or mechanical tying with equipment.
- Design of the structure for which it is being used, like buildings, bridges, dams, etc.
Different Types of Binding Wires Used in Construction
Though MS wire binding is one of the most popular forms, various other binding wires are used in construction, like black annealed baling wires, PVC-coated binding wires, black annealed baling wire, etc.
- Constructional binding wires, which is made by straightened cut wire
- Black annealed binding wires, which is used for daily tying, uses
- A round bar is a steel bar with a smooth surface used for construction works where high-strength reinforced concrete works are not required.
- Loop tie wire is also called tie wire or binding wire. These wires are made up of good quality low carbon steel used in construction, just like binding materials or baling wires.
- Galvanized wire
- Brass wire, aluminum wire
- Stainless steel wire
- PVC-coated binding wire
We would like to discuss a few of these in detail for you to have a better idea:
Black Annealed Baling Wire
The most popular size for this wire ranges from 16-22 gauges. These wires are made up of more flexible material. If you need a versatile type of binding wire for construction, black annealed baling wire will be the right choice.
It is more flexible and versatile and is resistant to corrosion, oxidation, and other forms of damage. Also, they are made up of high-quality material, and the most popular size of this wire ranges from 16-22 gauges.
Stainless Steel Binding Wires
Stainless steel wires are highly preferred for the harsh environment. Stainless steel reinforcement is used to prevent the problems linked with steel rusting.
PVC Coated Binding Wire
This type of binding wires is used primarily for tying epoxy-coated reinforcement. The epoxy coating acts like a barrier, preventing reinforcement bars’ corrosion.
Which binding wire will be the best for construction?
The binding wire used for the reinforcement of bars should be at least 18 gauge annealed wire conforming to IS 280 and free from oil, paint, grease, rust, etc. Also, it is important to choose a wire of high tensile strength of 250-430 N/sq.mm.
Conclusion:
In short, binding wire is meant to provide a secure hold to the different diameters of reinforcing bars and is used for a variety of purposes.
You need to buy only the high-quality binding wires for construction as it will be safe, versatile, and can be used for different purposes. Be very cautious about choosing the right quality and marketplace.
