Hunan bridge finishing rebar psb830psb930

Hunan finishing rebar (Scres-thread steel bars for the prestressing of concrete) is: prestressed concrete with rebar is on the whole root of large diameter steel rolling straight discontinuous external threads, high strength, high dimensional accuracy Article reinforcement. The bars at any cross section of the connector can be screwed with an internal thread on the nuts with threaded connection or screwed anchored. 1: strength grade prestressed concrete with rebar yield strength division level, code-named "PSB" plus the minimum specified yield strength expressed. P, S, B respectively Prestressing, Scres-thread, Bars English first letter. For example: PSB830 indicates the standard value 830MPa yield strength steel. 2: size steel nominal diameter range of 18mm ~ 50mm, this recommended standard steel nominal diameter 25 mm, 32 mm. The Company reserves all models. 3: Technical requirements for the analysis of reinforced steel smelting, sulfur and phosphorus content of not more than 0.040%. The manufacturer should choose and use the chemical composition and alloying elements, in order to ensure the process of working through different finished steel to meet the mechanical properties specified in Table 3 requirements. Analysis of the chemical composition of finished steel tolerances shall comply with the provisions of GB / T222's. Companies able to do random checks, please rest assured customers to buy used.
