Robust Corrosion ProtectionWith zinc plating or hot dip galvanization, Expansion Shell Bolts offer exceptional resistance against corrosion, ensuring durability and reliable performance in harsh environments such as mines or construction sites. This makes them suitable for long-term anchoring solutions even in exposed or damp conditions.
Engineered for Secure AnchoringThe unique expansion shell design ensures superior grip and high tensile strength. When installed in substrates like concrete or rock, rotating the bolt expands the shell, distributing force effectively and providing solid anchorage for heavy-duty applications. Their cylindrical shape and slotted shells further enhance stability.
Versatile ApplicationsExpansion Shell Bolts are widely used across industries including mining, tunneling, civil engineering, and construction. Their reliability and adaptability to various substrates and sizes make them a preferred choice for securely anchoring supports, brackets, equipment, and structural components.
FAQs of Expansion Shell Bolts:
Q: How are Expansion Shell Bolts installed in construction projects?
A: Expansion Shell Bolts are inserted into a pre-drilled hole matching the nominal bolt size. Once positioned, the bolt is rotated, causing the shell to expand and firmly anchor against the substrate, such as concrete, rock, or masonry.
Q: What benefits do zinc plating or hot dip galvanization provide?
A: These finishes significantly enhance the bolts corrosion resistance, making them ideal for environments exposed to moisture, chemicals, or harsh outdoor conditions, thus extending the longevity and reliability of the anchor.
Q: Where are Expansion Shell Bolts most commonly used?
A: They are extensively used in mining, tunneling, civil engineering, and general construction for anchoring supports, brackets, or other structural elements into hard substrates.
Q: Are Expansion Shell Bolts reusable after initial installation?
A: No, for maximum safety and performance, Expansion Shell Bolts are designed for single-use only and should not be reused after removal.
Q: What is the recommended drill hole diameter for these bolts?
A: The drill hole diameter should match the nominal bolt size. For instance, an M20 expansion shell bolt requires a 20mm hole for optimal fit and anchorage.
Q: Why is metric thread type used in these anchor bolts?
A: Metric threads, either standard or coarse, align with international standards and facilitate easy compatibility with other hardware commonly used in engineering and construction projects.
Q: What safety factors should be considered during installation?
A: Recommended torque values must be followed as per manufacturer guidelines, and only suitable substrates and matching hole sizes should be used. Proper installation ensures high pull-out resistance and reliable anchorage.
