Product Introduction

Foundation anchor bolts provide the critical connection between a concrete foundation and the steel structure installed above it. They are used to secure columns, machinery, pipe supports and structural equipment while transferring loads safely into the foundation.

ZSJH Steel supplies project-specific anchor bolts manufactured according to foundation drawings, bolt schedules and column base plate details. Customers can select different bolt shapes, materials, thread configurations, coatings and accessories to meet the installation and environmental requirements of each project.

Anchor bolts can be supplied separately or packaged together with nuts, washers, anchor plates, positioning templates and related steel structure components.

Product Range

L-Type Foundation Bolts

L-type bolts feature a right-angle embedded end that helps resist pull-out forces after the concrete has cured. They are commonly used for steel workshops, warehouses and light industrial structures.

Hooked Anchor Bolts

Hooked anchor bolts use a curved embedded section to create mechanical anchorage inside concrete. Hook radius, embedment depth and exposed thread length can be customized.

Straight Anchor Rods

Straight threaded rods are suitable for use with bottom plates, sleeves or other anchoring systems. They are frequently selected for heavy steel columns and machinery foundations.

Plate Anchor Bolts

A steel plate is welded or assembled at the embedded end of the rod to increase its anchoring area. Plate dimensions and thickness are produced according to the design.

U-Type Bolts

U-type bolts are suitable for fixing pipes, supports, frames and equipment. The distance between the two legs can be customized to match the connected component.

Standard Product Information

Corrosion Protection Options

Plain Steel

Plain steel anchor bolts are suitable for embedded applications or projects where protective treatment will be completed at the jobsite.

Electro-Galvanized Finish

Electro-galvanizing creates a clean and uniform surface suitable for indoor environments and applications requiring moderate corrosion protection.

Hot-Dip Galvanized Finish

Hot-dip galvanizing provides a thicker protective zinc coating and is recommended for outdoor, humid, coastal and industrial environments.

Project-Specified Coating

Alternative protective systems can be provided when required by the project specification. Coating selection should consider exposure conditions, service environment and required durability.

Matching Positioning Templates

Positioning templates help contractors maintain the correct spacing, orientation and projection height of anchor bolts before concrete placement.

We can fabricate single-layer or multi-layer steel templates based on the column base plate dimensions. Template holes are manufactured to match the specified bolt layout, helping reduce installation errors and improving the efficiency of steel column erection.

FAQ

Can you produce anchor bolts without a detailed drawing?

Yes. You may provide the basic dimensions, base plate layout and application information. Our team can help organize the information into a production drawing for confirmation.

What is the difference between plain and galvanized anchor bolts?

Plain bolts have no zinc protective layer, while galvanized bolts have a zinc coating that improves resistance to corrosion. The appropriate finish depends on the installation environment.

Can the thread length be customized?

Yes. Partial thread, extended thread and full thread designs can be manufactured according to installation requirements.

Can you supply replacement nuts and washers?

Yes. Additional nuts, washers and related accessories can be included in the order when required.

Are positioning templates available for large column bases?

Yes. We can manufacture customized templates for different bolt quantities, spacings and base plate dimensions.
