产品简介：There are two common classification methods for threaded steel: First, it is classified according to the cross-section shape of the cross-rib and the spacing of the ribs. For example, in the British standard (BS4449), threaded steel is divided into type I and type II. This classification mainly reflects the gripping performance of threaded steel. The second is based on performance classification (grade). For example, in the current implementation standard in China, threaded steel is (G B1499.2-2024), and threaded steel is divided into three grades according to strength level ( yield point/tile strength).

There are two common classification methods for threaded steel: one is to classify or classify according to the geometry, according to the cross-sectional shape of the ribeam and the spacing of the ribeams. For example, in the British Standard (BS4449), threaded steel is divided into Type I and Type II. This classification mainly reflects the gripping performance of threaded steel. The second is performance classification (grade), for example, in China's current implementation standard, in which threaded steel is (G B1499.2-2024), the threaded steel is divided into 3 grades according to the strength level (decreed point/tensile strength); in the Japanese industrial standard (JI SG3112), the threaded steel is divided into 5 categories according to comprehensive In addition, threaded steel can be classified according to the purpose, such as ordinary steel for reinforced concrete and heat treated steel for prestressed reinforced concrete.
