For example, PP2 10 1 stands for 10, a PP futures contract that expires in October. 0 1 The expiration date of the contract is 1 month, and the last transaction time of retail investors is the end of one month before the delivery month, that is, the end of 65438+February. (Individual investors) must close the contract that is about to enter the delivery month of 0 1 month.
1. Rebar futures are futures varieties with rebar as the subject matter. The steel futures that Shanghai Futures Exchange can trade are rebar futures and wire futures. The transaction unit of the rebar futures standard contract is per lot 10 ton, and the delivery unit is 300 tons per warehouse receipt. The delivery shall be an integral multiple of each warehouse receipt.
2. Steel bars are ribbed bars, which are divided into hot-rolled ribbed bars and cold-rolled ribbed bars. Rebar is also called deformed steel bar or special-shaped steel bar. Different from ordinary round steel, there are longitudinal bars and transverse bars on the surface, which are usually evenly distributed along the length direction. Rebar is a kind of small steel, which is mainly used for the skeleton of reinforced concrete building components. It is required to have certain mechanical strength, bending deformation performance and process welding performance in use. The billet used to produce rebar is carbon structural steel or low-alloy structural steel after calming and melting, and the finished rebar is delivered in hot-rolled shape, normalized or hot-rolled state.
3. There are two commonly used classification methods for steel bars: one is to classify according to the geometric shape of steel bars, and the other is to classify or classify according to the cross-sectional shape and spacing of transverse bars. For example, in British Standard (BS4449), steel bars are divided into type I and type II. This classification mainly reflects the grip performance of steel bars. Secondly, rebar is classified according to performance (grade). For example, in China standard (GB 1499), rebar is divided into three grades according to strength grade (yield point/tensile strength). According to Japanese industrial standard (JISG3 1 12), rebar can be divided into five categories according to its comprehensiveness. British Standard (BS446 1) also stipulates several grades of steel bar performance test. In addition, steel bars can also be classified according to their uses, such as ordinary steel bars for reinforced concrete and heat-treated steel bars for prestressed reinforced concrete.
