When it comes to structural integrity and safety, Keyed Expansion Mechanical Anchors stand out as a critical solution for demanding construction and engineering applications. These anchors are specifically designed for use in concrete and other masonry materials, offering exceptional load-bearing capacity, fire resistance, and compliance with stringent building codes. Manufactured by HEBEI HEX IMP. & EXP CO., LTD., a company with over two decades of global export expertise, these anchors combine advanced engineering with reliable performance to meet the needs of modern infrastructure projects.
The Keyed Expansion Mechanical Anchors are a type of post-installed fastener engineered for high-strength applications. Unlike traditional adhesive anchors, these mechanical anchors rely on a physical expansion mechanism to secure components to concrete surfaces. The M12 carbon steel variant is particularly suited for heavy-duty use, offering durability and resistance to corrosion. These anchors are fire-rated and IBC (International Building Code) compliant, making them ideal for use in critical structural and seismic applications.
The anchors utilize a single-tube undercut mechanism, which involves drilling a hole, undercutting the base cavity with a specialized drill bit, and inserting the anchor assembly. When tightened, the cone expansion mechanism activates, creating a secure mechanical interlock with the surrounding concrete. This design ensures maximum load capacity and long-term stability, even under dynamic loads.
These anchors are certified for fire-rated applications, meaning they maintain structural integrity during high-temperature events. This feature is critical in environments where fire safety is a priority, such as industrial facilities, commercial buildings, and infrastructure projects.
Compliance with the International Building Code (IBC) ensures that these anchors meet the minimum safety standards for construction in the United States and other regions that adopt IBC guidelines. This compliance is essential for projects requiring official approval from regulatory authorities.
From steel-to-concrete connections to seismic bracing, these anchors are designed for a wide range of applications. They are commonly used in bridge bearing assemblies, precast wall connections, and pipe/tray supports in earthquake-prone areas. Their adaptability makes them a preferred choice for engineers and contractors working on complex projects.
