The hot rolled square sectioned steel bars inside the scope of this standard must be delivered according to the dimensions shown on Figure 1 and Table 1. The edges must be as sharp as the hot rolling production suffices.

Table 1 - Preferred dimensions and theoretical weights of hot rolled square steel bars for general purposes.
 

Upon order request, all the acceptable deviations can be determined as plus tolerance.
Density: 7,85 kg/dm³ Uyar Çelik’s square production range is between 16mm-100mm.

The customer must inform about the desired length, length type and length range.
Upon request, the production can be made with plus tolerance.
