Product Description
Anchor bolts are essential pre-embedded fasteners used in steel structure engineering, equipment foundations and civil engineering projects. Unlike standard post-installed expansion bolts, anchor bolts are embedded in concrete during construction, providing greater anchoring force, higher stability and excellent resistance to overturning and pull-out. They are the core fastening components for large-scale equipment, steel structures in industrial buildings and tower foundations.
Structural Principles
Anchor bolts are pre-embedded anchoring components. During construction, they are positioned and secured in advance within the formwork; once the concrete has been poured, they become an integral part of the foundation. Through the interlocking action of the bolt shank, hook and anchor plate with the concrete, they provide strong load-bearing capacity and resistance to slippage and overturning, with a load-bearing capacity far exceeding that of ordinary post-installed expansion bolts.
Product Categories

L-shaped anchor bolts
A classic, widely used design featuring a simple structure and excellent value for money. The hooked end grips firmly into the concrete, making them suitable for embedding in foundations for light-duty equipment, small steel structures and pole supports; they are extremely versatile.
9-shaped anchor bolts
These offer greater anchoring depth and stronger grip, with superior pull-out resistance compared to the 7-shaped variety. Suitable for medium-duty equipment, factory columns and standard steel structure foundations, they are the mainstream choice in civil engineering projects.


Welded-plate anchor bolts
The shank end is welded to a thickened steel plate, providing a large contact area and uniform load distribution, thereby preventing loosening and deformation. With exceptional load-bearing capacity, they are specifically designed for heavy-duty steel structures, tower cranes, large machinery units and high-load infrastructure applications.
U-shaped anchor bolts
Featuring a double-threaded design, these are specifically used for securing pipes, cable trays and circular components, and are widely applied in plumbing, municipal pipework and equipment positioning applications.

Standard product specifications range from M16 to M30, with lengths from 500 mm to 1,000 mm. We also offer customisation for extra-long, extra-thick and non-standard dimensions, ensuring full compliance with the specifications required by all types of construction drawings.
Product Advantages
- Embedded anchoring, offering far greater stability than post-installed bolts: Cast as a single unit with the concrete foundation, it ensures even load distribution and delivers excellent resistance to pull-out, shear and overturning. It is resistant to loosening and displacement over the long term, making it suitable for permanent structural fixings.
- High load-bearing capacity, suitable for all applications from light to heavy duty: With a wide range of styles available—from lightweight brackets to heavy-duty steel structures and large-scale equipment—it covers pre-embedded scenarios involving low, medium and high loads, offering exceptional adaptability.
- Compliant with standards, ensuring hassle-free project acceptance: Manufactured in accordance with national standards, these products feature precise dimensions, standardised threads and mechanical properties that meet all requirements, perfectly satisfying site supervision acceptance and engineering audit standards.
- Flexible customisation to suit all types of drawings: We support customisation for any length, diameter, bend dimensions and welded plate specifications, and can process orders on a one-to-one basis according to construction drawings, resolving challenges associated with non-standard embedded fittings.
Applications
Anchor bolts are essential embedded components in infrastructure projects, with applications spanning a wide range of industrial and construction projects: column foundations for steel-framed workshops, embedded bases for machinery and equipment, foundations for tower cranes and hoists, bridge supports, municipal street lamp poles, CCTV poles, foundations for canopies and curtain walls, water conservancy pipeline equipment, mining equipment, boiler equipment, and foundations for large-scale warehouse racking systems—in short, any engineering scenario requiring permanent, load-bearing anchoring.
