Integrated Strata Control: The Synergy of Friction Bolts and Galvanized Mesh
As shown in our production facility, we specialize in the high-volume supply of the industry's "Golden Duo": High-Tensile Split Set Bolts and Galvanized Welded Wire Mesh.
1. Point Support: The Friction Stabilizer (Split Set)
Our Split Set bolts are engineered from high-grade strip steel to provide immediate, full-length frictional anchorage. By exerting constant radial pressure against the borehole wall, they accommodate rock mass movement while maintaining structural integrity.
2. Surface Support: Galvanized Welded Mesh
Bolting alone cannot prevent smaller rock fragments from falling between support points. Our galvanized wire mesh provides the necessary "areal support." The high-strength welds and superior galvanization ensure:
Corrosion Resistance: Essential for high-humidity or acidic environments.
Load Distribution: Effectively transferring surface pressure to the primary bolting system.
Operational Safety: Creating a secure "skin" for the protection of personnel and machinery.
FAQ
Q: What international standards do your self-drilling anchor bolts comply with?
A: Our SDA systems (including R-thread and T-thread) are manufactured in strict accordance with ISO 10208 and ASTM standards. We use high-strength seamless steel tubing to ensure superior tensile and yield strength for demanding mining and tunneling projects.
Q: Why are SDA bolts more efficient than traditional rock bolts in fractured ground?
A: Traditional bolts require a pre-drilled hole which often collapses in loose ground. The SDA system combines drilling, grouting, and anchoring into a single operation. This eliminates the need for casing pipes and prevents borehole collapse, saving up to 50% of installation time.
Q: How do your spherical nuts handle uneven rock surfaces?
A: Our precision-engineered spherical nuts (dome nuts), when paired with domed plates, allow for 7 to 10 degrees of angular compensation. This ensures that the bolt maintains a secure, perpendicular load distribution even when the tunnel face is irregular or uneven.
