Metal Building Material steel Semi Grouting Coupler
Main Features
1. Use solid 45# carbon or 50# steel as raw material.
2. Tensile Strenth is more than 540MPa.
3. There are 2 types, one is full grouting coupler(connected with rebar by concrete-based grouting material), and the other is semi/half grouting coupler(which one end is connected by threaded screw, and the other is connected by concrete-based grouting material).

| Note: 1. The bottom dimension in the table is the value of the sleeve raw material that meets the mechanical performance requirements of No. 45 steel in GB/T699-2015 (the measured yield strength and ultimate strength should not be less than J355-2015 Rebar Sleeve Grouting Connection Application Technology The standard specified in the regulations), the minimum size that can be selected when the sleeve manufacturer has a good level of quality control. 2. The minimum size of the measured sleeve should be measured in at least two directions, and the minimum value should be used for judgment. 3. The customer's special customized sleeve must meet the mechanical performance parameters (strength requirements) of the sleeve as a premise, and the size can be flexibly controlled. |
