Anchor bolts are special fasteners used to firmly fix components, equipment or structures onto base materials such as concrete, walls and rocks. They achieve high-strength anchoring through expansion locking, chemical bonding or mechanical interlocking, featuring stable connection, strong pull-out resistance, convenient construction and wide applicability. They are widely used in building curtain walls, steel structure installation, equipment fixing, bridge guardrails, decoration engineering, pipeline supports and other scenarios. Common types include expansion anchors, chemical anchors, wedge anchors, ceiling anchors, foundation anchor bolts and so on, serving as key components to ensure structural safety in modern construction and equipment installation.
