R25 R32 R38 R51 T76 Threaded Hollow Anchor Rod System with ISO10208 ISO1720 Certification for Concrete Reinforcement

Zhengde hollow anchor system combines anchoring and grouting functions in a single integrated solution. The system consists of five main components: hollow drill pipe, plastic drill bit, grout stopper, backing plate, and nut. The engineering plastic drill bit features slurry holes and dust removal capabilities.

Hollow anchors replace traditional mortar anchors for radial reinforcement, eliminating common construction defects such as incomplete grouting and inability to achieve pressure grouting, ensuring superior project quality.

Ideal for stabilizing unstable slopes with simple processes, low costs, quick construction, and remarkable effectiveness.

Used for reinforcing building foundation pits with simple processes that enable pressure grouting and improve surrounding rock conditions.

The hollow anchor system features a fully threaded rod body, anchor head, grout stopper, backing plate, and nut. Each component is engineered to maximize grouting efficiency and density, with mortar capable of penetrating surrounding rock cracks under pressures up to dozens of kilograms (specific parameters subject to design requirements).

• Hollow design functions as grouting pipe, eliminating mortar loss from grouting pipe removal
• Full grouting capability with pressure grouting implementation for enhanced project quality
• Superior centering with complete mortar coverage along entire anchor length, preventing corrosion and ensuring long-term support
• Easy installation with backing plates and nuts requiring no on-site thread processing
• Compatible with specialized grouting pumps and anchor rod grouting technology

Manufactured in compliance with ISO10208 and ISO1720 international standards, ensuring consistent performance and reliability.
