Rebar form factor: the surface shape and size ribbed steel tolerances. Ribbed steel horizontal rib design principles should meet the following requirements: the angle β transverse ribs and reinforced axis of not less than 45 degrees 12mm rebar manufacturer, when the angle of not more than 70 degrees, on opposite sides of the cross rib reinforcement direction be contrary; transverse ribs is not greater than the nominal spacing l reinforced 0.7 times the nominal diameter; transverse ribs and reinforced side surface of the angle α of not less than 45 degrees; reinforced the gap between the ends of adjacent transverse ribs (including a longitudinal rib width) on both sides should not be greater than the sum of the nominal 20% reinforced perimeter. Ribbed steel usually with longitudinal ribs, or without longitudinal ribs. Steel specification: steel factory quality due certificates of inspection report 12mm rebar model, in accordance with regulations for the mechanical properties of the sample batch extraction test, qualified before use. Steel surface or each bundle (plate) steel shall have identification; steel surface without cracks, scars, creases and corrosion phenomena. Steel manufacture in the field, configure steel bending machine, steel cutting machine and winches for steel processing. 12mm rebar much money | Dingding cold rolled | 12mm rebar by Ding Ding Industrial Co., Ltd., Henan Province.
