Half grout sleeve coupler - a revolutionary product in the coupler industry. Made with special customized material, it meets the requirements of "Grouting sleeve for steel connection" JG/T 398-2019. The performance index of the joint meets the Grade I joint standard specified in JGJ 355 of the "Technical Specification for Mechanical Connection of Steel Bars"

1. Precision and Accuracy: The half-grout filled coupler eliminates the hassle of location deviation that can occur with whole grout-filled couplers. Say goodbye to wasted time and effort.

2. Efficient and Cost-effective: By reducing the length of the coupler by 1/3 and cutting the grouting work in half, our sleeve guarantees a high-quality joint without compromising on time or resources.

3. Exceptional Strength: With high tensile and yield strength, half-grout filled coupler meets the JGJ107, JG/T397 Standard, ensuring robust and reliable connections.

4. Versatile Connection: half-grout filled coupler is compatible with reinforcing bars of the same or different diameters, making it suitable for a wide range of construction projects, including buildings, roads, and bridges.
