Rebar anchor bolts are critical components in construction, providing unmatched stability for concrete-to-steel connections. With a global market projected to grow at 6.2% CAGR through 2030, demand for high-performance 20 mm anchor bolts has surged, driven by infrastructure expansion. These bolts are engineered to withstand tensile loads exceeding 50 kN, making them indispensable for seismic-resistant structures. Their ribbed design enhances bonding with concrete, reducing slippage risks by up to 40% compared to smooth variants.
20 mm anchor bolts dominate heavy-load applications due to their optimal balance between strength and adaptability. Key advantages include:
Advanced galvanization processes extend service life to 50+ years in harsh environments, outperforming standard epoxy coatings by 3:1 in accelerated aging tests.

Specialized configurations address unique project requirements:
Precision CNC threading ensures ±0.05 mm dimensional accuracy, while robotic welding systems maintain consistent throat thickness across batches.
All rebar anchor bolts
undergo rigorous quality checks:
Emerging smart anchor bolts integrate strain sensors, providing real-time structural health monitoring. Recent trials in California bridge retrofits demonstrated 92% accuracy in stress prediction, enabling proactive maintenance. Sustainable manufacturing techniques now reduce CO₂ emissions by 18% per ton of production, aligning with UN Sustainable Development Goal 9.

A: Rebar anchor bolts secure structural elements to concrete foundations. They are commonly used in construction to reinforce connections between steel and concrete. Their threaded design ensures high load-bearing capacity.
A: 20 mm anchor bolts provide greater tensile strength and load capacity than smaller diameters. They are ideal for heavy-duty applications like bridge supports. Size selection depends on structural requirements.
A: Common types include wedge anchors, sleeve anchors, chemical anchors, drop-in anchors, expansion anchors, adhesive anchors, screw anchors, undercut anchors, strike anchors, and rebar anchor bolts. Each suits specific materials and load conditions.
A: They are embedded into wet concrete or secured via drilling and epoxy in cured concrete. Proper alignment and curing time are critical. Installation often follows engineering specifications for structural integrity.
A: Key factors include load requirements, base material (concrete strength), environmental conditions (moisture, temperature), and project design. Consulting engineering guidelines ensures optimal performance and safety.
