In modern underground construction and slope stabilization, efficiency isn't just a goal — it's a necessity. The H22 Hollow Hexagonal Anchor Bolt represents an advanced all - in - one geotechnical solution that seamlessly integrates drilling, grouting, and anchoring into a single, high-performance process.
The standout feature of the H22 system is its hexagonal geometry. Unlike standard round rods, the H22 profile offers superior contact surface for drilling rigs, ensuring:
Deep hole drilling often faces two critical challenges : heat and chip accumulation. The H22's longitudinal hollow channel allows for high pressure air or liquid cooling. This " internal artery " flushes out rock chips in real - time , protecting your drill bits from overheating and extending the service life of your equipment.
Crafted from premium high-strength alloy steel, each H22 rod undergoes rigorous quenching and tempering (Q/T) heat treatment. The result is uniform internal stress distribution that delivers:
The versatility of the H22 hollow bolt makes it the preferred choice for demanding applications:
No two geological sites are the same. That's why we offer customized geotechnical services, including specialized anti-corrosion coatings for acidic soils, bespoke lengths, and reinforced thread connections for ultra-high-stress zones.
