Expansion Bolts & Anchors
Understanding Expansion Bolts & Anchors: Types and Applications
Chemical Anchors
Chemical Anchors are a modern anchoring technique using a resin-based adhesive to secure the anchor into place. Their exceptional holding power in both cracked and uncracked concrete makes them ideal for high-load applications. Chemical anchors are widely used in the construction and civil engineering industries, particularly for attaching structural supports, machinery bases, and façade elements.
Chemical Stud Nuts
Chemical Stud Nuts function similarly to chemical anchors but are designed specifically for attaching threaded rods. This method combines the chemical adhesion properties with the mechanical strength of studs, providing a robust solution for heavy-duty anchoring. They find their application in large-scale construction projects, including bridges, highways, and industrial facilities, where precision and strength are paramount.
Drop-In Anchors
Drop-In Anchors are designed for anchoring into concrete with a pre-drilled hole. Upon insertion, the anchor expands, securing itself. They are commonly used for mounting pipes, sprinkler systems, and electrical conduits. Industries such as mechanical, electrical, and plumbing benefit greatly from the use of drop-in anchors for their easy installation and reliability in overhead applications.
Eye Expansion Bolts
Eye Expansion Bolts are expansion anchors with an eye head for hooking or tying down objects. They are typically used in construction for temporary anchoring, scaffolding, and in electrical installations for hanging cables. Their versatility makes them suitable across various industries, including construction, utilities, and telecommunications for lightweight anchoring solutions.
Hook Expansion Bolts
Similar to Eye Expansion Bolts, Hook Expansion Bolts feature a hook-end design, making them ideal for hanging and support applications. These bolts are particularly useful in commercial and residential construction for hanging signs, lights, and decorative elements. They offer a secure and removable anchoring solution, which is highly valued in the interior design and renovation sectors.
Loose Expansion Bolts
Loose Expansion Bolts are versatile anchors designed for medium-duty anchoring in concrete, stone, and brick. Their expansion mechanism secures the bolt as it is tightened. Common uses include mounting frames, brackets, and machinery. This type of bolt is favored in the manufacturing and construction industries for its flexibility and strength in various substrates.
Projecting Expansion Bolts
Projecting Expansion Bolts are similar to loose expansion bolts but are designed for applications where the bolt projects from the wall or surface. They are chosen for projects requiring a protruding bolt for the attachment of items such as barriers, guide rails, and signage. These bolts are particularly applicable in the construction and transportation industries.
Shield Expansion Bolts
Shield Expansion Bolts use a shield (usually metal) that expands against the material for anchoring. These are particularly useful for heavy-duty anchoring in concrete and masonry where high load capacity is required, such as in securing heavy machinery, structural supports, and industrial shelving.
Sleeve Anchors
Sleeve Anchors offer a reliable solution for anchoring into concrete, brick, and block. Their sleeve expands upon tightening, creating a secure hold. Applications include fixing radiators, shelves, and cladding to walls. They are versatile and widely adopted in construction, renovation, and mechanical industries due to their general-purpose nature.
Wedge Anchors
Wedge Anchors are heavily relied upon in the construction industry for high-strength anchoring into concrete. The anchor expands as the bolt is tightened, ensuring a strong hold for supporting structural frames, facades, and other heavy elements. They are indispensable in construction projects requiring maximum reliability and load-bearing capacity.
