What are the Differences Among Different Grade of Reinforcing Bar Sleeve?
The reinforcing bar connection sleeve are used to connect two independent reinforcing bars together. According to the differences in their own tensile strength, compressive strength and other properties, the reinforcing bar sleeves are divided into first-class steel, second-class steel and third-class steel. What is the classification standard of the grades of reinforcing bar sleeves, and what are the differences among different grades of reinforcing bar sleeves? First, the reinforcing bar sleeve with a tensile strength greater than or equal to 1.1 times the ultimate tensile strength of the reinforcing bar is a first-class reinforcing bar connection sleeve. The tensile performance of the first-class reinforcing bar sleeve is the best and is suitable for the parts with relatively high tensile strength requirements. Second, the reinforcing bar sleeve with a tensile strength greater than or equal to the standard value of the ultimate tensile strength of the reinforcing bar is...
