Reinforced according to different kinds of steel, grade, grade, size acceptance ?? manufacturer batches before use to confirm eligibility. Reinforced in the transport, storage, processing should Textile rust, contamination and deformation. Grade steel, type and diameter design requirements should be adopted, when the need to substitute cold rolled straight bars suppliers, should make changes to the original design of the unit design. Before pouring concrete response acceptance cold rolled steel were hidden spot straight bars, confirm compliance with design requirements. Steel connection: Direct structural components to withstand dynamic loads in cold-rolled steel prices straight, longitudinal reinforcement shall not use banding connector. There are requirements for seismic reinforcement of the joint force, should give priority to the use of welding or mechanical connections. Steel banding lap joint connecting sections of the lap length is 1.3 times the length of the lap joint where the lap joints connecting the midpoint of the segment length located within the zone belong to the same connection, the connection within the same segment longitudinal reinforcement lap .
