Product introduction
Our modular expansion joints are engineered for rapid installation and long-term performance, designed to absorb thermal movement and live-load deflections. Fabricated from high-strength Q345 steel, our joints comply with JTG D64-2015 standards. We utilize advanced welding techniques, including CO2 Gas Shielded Welding and Robotic SAW, to ensure a perfect bond between the steel profiles and the rebar anchors, guaranteeing durability under heavy traffic.
