When steel manufacture, steel processing table to review the design, cutting table checking for errors and omissions. When the construction of reinforced substitution if necessary, we must fully understand the design intent and the substitution material properties 12mm rebar rod, strict compliance with the various provisions of the existing reinforced concrete design specifications, and not to the area of ??high-strength steel, such as the substitution of low intensity reinforced. Where important parts of steel wire rod substitution 12mm rebar manufacturing plant, must obtain Party, agreed to design units, and only when there is a written notice substitution. Reinforced by rolling contour points: smooth steel: I grade steel (Q300 steel rebar) are rolling smooth circular section for 12mm rod rebar supplier, in the form of a round plate 12mm rebar wire rod plant, a diameter not greater than 10mm, a length of 6m ~ 12m. Ribbed steel: a spiral-shaped, herringbone and crescent are three general Ⅱ, Ⅲ grade steel rolling herringbone, Ⅳ grade steel rolled into a spiral and crescent. Steel wire (min two kinds of low carbon steel and carbon steel) and the Strand. Cold-rolled and twisted bars: cold-rolled and cold-twisted shape. 12mm rebar wire rod mill | 12mm rod rebar | Ding Ding Ding Ding cold rolled by Industrial Co., Ltd., Henan Province.
