Key Features
1. Patented Water-Activated Expansion Mechanism
Core material: High-strength Q235/Q355 threaded steel rod
Outer layer: Premium water-swellable polymer sleeve
Expansion ratio: ≥300% within 5–10 minutes upon moisture contact
Anchoring force: 8–12 Tons per anchor
Working principle: Moisture (groundwater, construction water, or manual spraying) activates radial expansion, creating a tight friction lock with the drill hole walls for stable bonding in rock, soil, and concrete.
2. Certified Quality & Customizable Specifications
Certifications: ISO9001, ISO 898-1, ASTM A325, EU CE
Diameter: Standard 12mm(PM12),14mm,16mm; customizable 10–20mm
Length: Standard 100/200/300mm; extendable up to 800mm
Polymer sleeve: Standard(0–60℃), heat-resistant(up to 80℃), low-temperature(down to -40℃)
Surface treatment: Hot-dip galvanizing(430–600g/㎡), epoxy coating(coastal anti-corrosion), bare steel(dry environments).
3. Performance & Installation Advantages
Tool-Free Installation: No hydraulic pumps or heavy machinery; cuts labor cost by ~40%
Rapid Anchoring: 5–10 min curing; ideal for fast-track overseas projects
High Safety: Shear resistance 110–240kN; stable load, zero material loss
Wide Adaptability: Works in soft rock, broken zones, desert, coastal & permafrost regions
Cost-Effective: Lightweight for low freight; service life ≥10 years; minimal maintenance.

Step-by-Step Installation Guide
Preparation
Drill & Clean
- Drill holes per drawing; use spiral bits for soil/soft rock, diamond bits for hard rock
- Clean dust/debris with compressed air or brush
Moisturize & Insert
Dry areas: Spray 2–5ml water into hole; coastal/humid areas: no extra water
Insert anchor gently; avoid hammering to protect polymer sleeve
Set & Cure
Tighten nut lightly (torque ≤30N·m)
Cure 5–10 minutes (15min in low temp); no loading during curing.
Regional Installation Notes
Dry/Desert: Increase water spray; store in a shaded, cool place
High-Temp Mines: Use a heat-resistant sleeve; install in shade; cool holes
Coastal/Humid: Choose epoxy-coated for salt-spray resistance
Permafrost: Preheat hole to 5–10℃; use low-temp sleeve; spray warm water(15–20℃).
