ZSJH
ZSJH Steel manufactures customized anchor bolts designed to securely connect steel columns, equipment bases and structural frames to reinforced concrete foundations. Our anchor bolt systems provide reliable load transfer and help maintain the stability, alignment and long-term performance of steel structures.
We supply L-shaped, J-shaped, U-shaped, straight, plate-ended and fully threaded anchor bolts. Dimensions, materials, thread lengths, surface treatments, nuts, washers and positioning templates can be customized according to project drawings.
Our anchor bolts are widely used in steel structure workshops, warehouses, factories, logistics centers, power plants, equipment foundations and other industrial construction projects.

L-shaped anchor bolts feature a 90-degree bent end that provides strong anchorage inside concrete. They are commonly used for steel column bases, light industrial buildings and general foundation connections.
J-shaped anchor bolts have a curved embedded end that improves resistance to pull-out forces. They are suitable for structural foundations, equipment bases and prefabricated steel buildings.
U-shaped anchor bolts are used to secure pipes, steel frames, machinery and structural components. Bolt spacing, leg length and thread length can be manufactured according to drawings.
Straight anchor bolts can be fully or partially threaded and are often used with anchor plates, sleeves or chemical anchoring systems. They are suitable for heavy structural and equipment foundations.
Plate-ended anchor bolts use a welded or forged end plate to increase the bearing area inside concrete. They are suitable for applications requiring higher pull-out resistance.
