Foundation Anchor Bolt

Energet Solar focuses on the production and customization of Solar Foundation Anchor Bolt, fully compliant with international photovoltaic foundation construction codes and outdoor steel structure safety standards. This series of anchor bolts is specially developed for solar foundation fixing scenarios, widely used in concrete foundation embedding, ground bracket anchoring, steel base fixing and large-scale PV support system grounding construction, being an indispensable primary fastener for all ground photovoltaic projects.

Manufacturing Design

Unlike standard assembly fasteners, foundation anchor bolts are primarily designed for embedment in concrete foundations. They are suitable for applications requiring long-term load-bearing capacity, such as solar mounting systems, steel structures, and equipment foundations. Manufactured using integral forging and one-piece bending processes, the bolts feature a stable structure that resists deformation under sustained loads.

The tail section features a hook or L-shaped design, ensuring secure anchorage within the concrete. This enhances pull-out resistance and minimizes the risk of foundation displacement, making them ideal for connections subject to long-term static loads as well as external forces like wind and snow loads.

Material

The bolts are manufactured from high-quality carbon steels such as Q235B and Q355B, offering excellent tensile strength, shear strength, and fatigue resistance. Threads are produced via a rolling process, resulting in precise profiles and consistent dimensions; they are fully compatible with nuts, washers, and other fasteners, ensuring reliable connections and smooth installation.

Surface Treatment

To suit various operating environments, we offer surface treatments such as hot-dip galvanizing and ZAM (Zinc-Aluminum-Magnesium) coatings. These finishes enhance corrosion resistance in humid, coastal, and outdoor settings, thereby extending the service life of the foundation connectors.

Quality Inspection

Our facility is equipped with forging machinery, automated bending equipment, thread-rolling machines, and testing instruments, enabling standardized production from raw material processing to final product inspection. Each batch undergoes dimensional, thread, tensile, and coating quality checks to ensure compliance with engineering drawings and project specifications.

Customization

We offer customization of foundation anchor bolts to meet specific project requirements, including length, diameter, thread specifications, bending configuration, embedment depth, and surface treatment. We can tailor production plans based on solar mounting foundation types, concrete grades, and installation requirements to satisfy the needs of diverse engineering projects.

How to Select the Right Foundation Anchor Bolt

1. Select According to Load Requirements

For projects with higher wind pressure, snow load or heavier structures, higher-strength materials and larger diameter bolts are recommended.

Common options:

- M12: Light-duty structures

- M16: Standard PV applications

- M20: Heavy-duty structures

2. Select According to Foundation Type

Different concrete foundation designs require different:

- Embedment depth

- Bolt length

- Bending configuration

The anchor bolt should match the foundation drawing before installation.

3. Select According to Environment

For normal outdoor environments:

- Hot-dip galvanized anchor bolts are commonly used.

For coastal or high-humidity areas:

- ZAM coated anchor bolts provide enhanced corrosion protection.

Installation Precautions

Proper installation directly affects the anchoring performance and service life.

1. Confirm embedment depth according to engineering drawings.

2. Maintain correct bolt spacing and vertical alignment during concrete pouring.

3. Protect exposed threads from concrete contamination and mechanical damage.

4. Avoid unauthorized cutting, welding or bending modifications on-site.

5. Select appropriate corrosion protection according to local environmental conditions.
