On-site, steel rebars are commonly subjected to cutting and shaping using a variety of tools and techniques. The typical process entails the following steps:
1. Measurement: Prior to anything else, the rebars are measured to determine their required length and shape. Measuring tapes, rulers, or other measuring devices are employed for this purpose.
2. Marking: Once the measurements have been taken, the rebars are marked at the appropriate points using chalk or a marker. These markings serve as guidelines to ensure accurate cutting and shaping of the rebars.
3. Cutting: Mechanical or hydraulic cutting tools are then utilized to cut the rebars along the marked lines. Rebar cutters, angle grinders with cutting discs, or portable band saws are some commonly employed tools. These tools are specifically designed to handle the high strength of steel rebars, resulting in clean and precise cuts.
4. Shaping: After the rebars have been cut to the desired lengths, they can be further shaped as required. This shaping process involves bending the rebars to specific angles or curves. Manual rebar benders or electric rebar bending machines are commonly used for this purpose. These tools enable accurate shaping of the rebars, ensuring compliance with the necessary structural design.
5. Tying: Once the rebars have been cut and shaped, they are often bound together using wire or rebar tying machines. This binding process aids in securing the rebars in their designated positions within the concrete structure.
It is important to emphasize that the cutting and shaping of rebars on-site necessitate skilled workers who possess the necessary training to handle the tools and observe appropriate safety measures. These workers must also possess a solid understanding of the structural requirements and be capable of interpreting construction drawings to accurately cut and shape the rebars in accordance with the project specifications.
Steel rebars are commonly cut and shaped on-site using various tools and techniques. The process typically involves the following steps:
1. Measurement: The rebars are first measured according to the required length and shape. This is done by using measuring tapes, rulers, or other measuring devices.
2. Marking: Once the measurements are taken, the rebars are marked at the appropriate points using chalk or a marker. These marks serve as guidelines for cutting and shaping the rebars accurately.

5. Tying: Once the rebars are cut and shaped, they are often tied together using wire or rebar tying machines. This tying process helps to secure the rebars in place and maintain the desired positioning within the concrete structure.
It is important to note that the cutting and shaping of rebars on-site require skilled workers who are trained in handling the tools and following proper safety precautions. These workers must also have a good understanding of the structural requirements and be able to interpret construction drawings to accurately cut and shape the rebars according to the project specifications.
Steel rebars are typically cut and shaped on-site using handheld tools such as rebar cutters and benders. Rebar cutters are used to accurately cut the rebars to the required length, while rebar benders are used to shape the rebars into various configurations such as bends, hooks, or stirrups. These tools allow construction workers to customize the rebars according to the specific needs of the project, ensuring a precise and efficient installation.
