The rebar for futures trading is suitable for HRB400 or HRBF400, which is grade 3 rebar for construction, which is different from the threaded pipe. Rebar for delivery is a brand designated by the exchange, but it does not meet the quality requirements, which is why many steel mills want to register delivery brands. Can be used as a sales channel. It should be noted that only corporate customers can deliver, and individuals can't. Guo Xin Futures Agency Department
