Bundle and coil sizes Reinforcing steel bars are manufactured in 6 to 12 m length and with maximum deviation of -0/+100 for standard length. Upon agreement with the customer steel rebar can be manufactured of other length. The bundle weight is up to 5 t. Steel rebar in coils is produced with weight up to 600 kg and kg. The products are bound with wire rod of 5.5 to 7.0. The products are marked with label containing the following data: - Name and (or) trade mark of the manufacturer; - Name of the customer; - Contract/specification number; - Country of destination; - Dimension of the steel products (size length); - Heat number; - Batch number; - Weight. Note. Content of marking may be changed as per agreement between the customer and manufacturer. Deformed reinforcing steel can be marked with identification to state the manufacturing company strength grade etc. 7
