Equipped with advanced machinery and a skilled team, we maintain strict quality control to deliver superior products for various building projects.
At Sinodrills, ensuring the safety and reliability of our self-drilling anchor systems (SDA) is our top priority. Through strict adherence to international standards and robust internal quality control processes, we deliver superior products that meet the demands of complex engineering projects.
The self-drilling anchor system is an advanced anchoring solution on the market. It provides stability in soil or rock formations and is a key anchoring system in rock reinforcement projects, ensuring safety and structural rigidity.
Our self-drilling anchor is equipped with different parts. At the drilling end is the anchor bit, which creates the borehole while facilitating grouting. The anchor bolt, serves as the primary support structure. The anchor coupler extends the bolt's length when necessary, while the anchor plate distributes surface loads to ensure stability. Finally, the anchor nut locks the system securely in place, completing the setup for optimal performance.
