1. Used for cutting materials and shaping rebar; the length of each rebar bar is determined through calculations to facilitate shaping. 2. Used for project cost settlement; it shows how much rebar was actually used based on the material lists.

1. The dimensions indicated in the reinforcement layout diagram of a component are generally the outer dimensions of the rebar, that is, the dimensions measured from the outer surface of the rebar to another outer surface, and these are referred to as the external dimensions. When processing steel bars, acceptance is generally also carried out based on the external dimensions. Before processing, the steel bars are cut in a straight line; if the cutting length is calculated based on the total outer dimension of the bars, the dimensions of the processed bars will be larger than the required outer dimensions as per the design, or the straight section of the hooks will be too long, resulting in waste of material. This is because when the rebar bends, its outer surface stretches while the inner surface shortens, with only the length of the central axis remaining unchanged. There is a difference between the outer dimension of the rebar and its axial length; cutting according to the total outer dimension is inaccurate. Only by cutting according to the axial length of the rebar can the shape and dimensions of the finished rebar meet the design requirements. 2. The dimensions of the rebar framework specified by designers in the construction drawings often do not include the hook sections at the ends of the rebar members that have been bent into shape. The size requirements for these hook sections are usually clearly defined in the standards of various industries. When preparing the rebar at the construction site, if the rebar is cut according only to the dimensions given in the construction drawings, then there will be no need for those hook sections at the ends of the rebar members; therefore, this additional length must be included when cutting the rebar in a straight line.
