Foundation Anchor Bolts Manufacturer in China

Ningbo Teng Qi Fasteners Co., Ltd is a leading foundation anchor bolts manufacturer in China. Foundation anchor bolts, also known as anchor rods or anchor bolt, are essential components used in the construction industry to secure various structures to concrete foundations. These bolts are typically made of steel and have a threaded end to which nuts and washers can be attached.

The primary purpose of foundation anchor bolts is to provide a secure connection between the building or structure and the foundation, preventing lateral movement and ensuring stability during earthquakes, high winds, or other forces that could potentially cause the structure to shift or collapse.

During the construction process, the anchor bolts are embedded into the concrete foundation before it sets and hardens. Once the foundation is ready, the building’s structural elements, such as walls, columns, or steel frames, are positioned over the anchor bolt. Nuts and washers are then tightened onto the exposed threaded ends of the bolts to create a strong and reliable connection.

Properly installed foundation anchor bolt play a crucial role in the overall structural integrity and safety of the building, making them a critical component in construction projects.

Specification of foundation anchor bolts:

Foundation anchor bolts are critical components used to secure structural elements to a concrete foundation. Their specifications can vary depending on the specific application and structural requirements. However, here are some common specifications for foundation anchor bolts:

Product NameFoundation anchor bolts
Type:1.Double-ended anchor bolt
2.J tyle anchor bolts
3.L type anchor bolts
4. T type anchor bolts
Material:SS400 S355 ASTM A36 A307
ASTM A193B7
Length:The length of foundation anchor bolts is usually determined by the thickness of the concrete foundation and the height of the structure being anchored. The bolts need to extend sufficiently above the concrete surface to allow for the attachment of nuts and washers while securely anchoring the structure.
Diameter: The diameter is chosen based on the load requirements and the structural design.
Metric: M6-M100
Imperial:1/4"-4"
Thread Length:The threaded portion of the anchor bolt that extends above the concrete surface allows for the attachment of nuts and washers. The thread length is usually several inches long to provide enough thread engagement for a secure connection.
Bend or Hook:A bent or hooked end to increase their anchoring capacity by providing additional resistance against upward forces.
Class/Grade:F1554 GR. 36, 55, and 105-ksi
Class 4.8/8.8/10.9
Manufacturing Process:wire drawing, bending, thread rolling, surface treatment
Surface treatment:Black Oxide Coating/Zinc Plating (Electroplating)/Hot-Dip Galvanizing/Mechanical Galvanizing/Dacromet Coating/Painting or Powder Coating
Application Industry:Construction/Machinery/Infrastructure/Electrical

It’s essential to consult with a structural engineer or follow local building codes and regulations to ensure the proper selection and installation of foundation anchor bolts for a specific construction project. Additionally, the use of appropriate materials and proper installation techniques is crucial to ensure the bolts perform their intended function effectively.

Quality of foundation anchor bolts:

Control MethodDetail
Material Inspection:Verify the material's composition, heat treatment, and quality upon receipt. Conduct metallurgical analysis to ensure the material properties meet the standards.
Process Control:Implement strict process control measures for heat treatment, machining, threading, and any other manufacturing steps. Maintain consistent process parameters to ensure uniform quality.
Inspection Points:Introduce inspection points at various stages of manufacturing to check for defects, dimensions, and quality. Inspect threading, dimensions, surface finish, and other critical parameters.
Sampling and Testing:Regularly sample products for testing, such as tensile testing, hardness testing, and metallurgical analysis, to ensure they meet the required specifications.
Thread Inspection:Thoroughly inspect threading using proper thread gauges to ensure accurate dimensions and fit with mating components.
Traceability:Implement a traceability system to track each fasteners journey from raw material to final product. This aids in accountability and recalls if necessary.
