T111 Large-Diameter Self-Drilling Anchor Bar
T111 features a large bar diameter and robust overall structure, making it suitable for reinforcement projects requiring extra-long anchoring, deep anchoring, and high structural stability beyond the capabilities of conventional anchor bolts.
T111 Large-Diameter Self-Drilling Anchor Bar Overview
The T111 Large-Diameter Self-Drilling Anchor Bar is designed for high-capacity ground reinforcement and heavy-duty anchoring applications. With a 111 mm outer diameter, the T111 is available in configurations with ultimate load capacities of up to 3,650 kN and yield capacities of up to 2,750 kN. Its large hollow section supports drilling and grouting through the bar, helping form an integrated anchoring and ground reinforcement system.
