Welcome to inquire! Contact: Liu. Cold-rolled ribbed steel Measure: horizontal rib height is measured by measuring the same section height of each column is the mean value of transverse ribs; transverse rib spacing distance by measuring the average method, which measure taken in the same column with the first transverse ribs 11 a transverse ribs straight from the center of 8mm cold rolled steel stock, divided by the average value of 10 is the transverse rib spacing. Size measurement accuracy is accurate to 0.02mm. When measuring weight deviation 8mm cold rolled steel rebar straight specimen length should not be less than 500mm. Length measurements accurate to 1mm, weight measurement should be accurate to 1 g. Reinforced by the production process points: hot-rolled, cold-rolled, cold-drawn steel cold-rolled straight 8mm rebar producers, as well as to Ⅳ grade heat-treated steel made of heat-treated steel, higher strength than the former. According to the role in the structure of the points: compression reinforcement, tensile reinforcement, erect steel, distribution of steel bars, stirrups and so on. Many different types of steel, usually by the production process according to the role in the structure of the use of sub-classification.
