Specification

SEODescription

The Φ43-45 expansion fittings with Ordinary expansion 8x100mm configuration are heavy-duty 8x100mm mechanical anchors designed for structural fastening in concrete and masonry substrates. These fittings feature a 43-45mm borehole compatibility range and utilize an 8mm diameter expansion bolt with 100mm embedment depth, delivering up to 25kN tensile strength in C30 concrete. The galvanized steel construction supports operation in -20°C to +80°C environments, requiring precise 45mm diameter drilling for optimal performance. Commonly applied in construction, infrastructure projects, and industrial equipment installations, their key advantages include high vibration resistance and corrosion protection. Limitations include strict borehole tolerance requirements and reduced efficiency in low-density substrates. The system operates without electrical interfaces, relying purely on mechanical expansion principles for load transfer.

SEOQandA_Product

question:What if the expansion tube doesn't fit the drilled hole?
answer:Verify hole diameter matches specifications and ensure proper drilling tools are used for alignment.
question:Why does the expansion tube fail to expand properly?
answer:Check material hardness and installation torque; use high-strength tubes or torque wrenches if needed.
question:How to prevent corrosion in humid environments?
answer:Opt for corrosion-resistant materials like stainless steel or galvanized tubes and assess environmental conditions.
question:What causes loosening under load?
answer:Reinstall with correct pre-tension or apply thread-locking adhesive to secure connections.
question:Why does the expansion tube crack during use?
answer:Ensure applied load is within rated capacity and replace tubes with visible defects immediately.
