Advantages of Expansion Bolts

Expansion bolts offer significant advantages in construction, machinery installation, and equipment fixing, primarily due to three characteristics: structural stability (high load-bearing capacity and strong tensile strength), wide applicability (suitable for various substrates such as concrete/brick walls), and convenient construction (ready to use immediately after installation). Their mechanical locking design provides a tensile strength of over 51.4kN, making them suitable for high-strength applications such as bridges and tunnels. The multi-piece expansion sleeve and tapered structure further enhance seismic resistance (up to seismic grade 8). Installation requires only three steps: drilling, insertion, and tightening, saving over 30% of construction time, and eliminating the need for pre-embedded parts.
