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.
