Formwork Tie Rod

• Low carbon steel Q235--Break loading capacity about 90KN
• Highly strength Grade 45 steel---Break loading capacity about 140KN
• Grade 830 for highest loading capacity---Break loading capacity about 180KN

Formwork tie rods are widely used in various construction projects including residential buildings, commercial structures, bridges, and other civil engineering works where concrete is poured into forms. Their ability to maintain uniform wall thickness and structural stability makes them indispensable in achieving high-quality concrete finishes.

WRK only offers high quality formwork tie rod for safe construction fields.

Producing formwork tie rods from steel involves several key steps, including material selection, fabrication, and finishing processes.

Steel Type

WRK always choose the appropriate type of steel for the tie rods. Weatherlow-carbon orhigh-strength steel, We test the chemical composition and mechanical properties of each batchof raw materials to ensure that the materials we use strictly comply with normal standards

Forming the Tie Rods

Threading: Use a threading machine to cut threads on both ends of the tierod, ensuring they are compatible with the tie rod nuts and washers. Alternatively, for tierods with a smooth end, a specific end shape (like a hook) may be formed. Bending (if required): If the design calls for bends, use a hydraulic bender or similar equipment to achieve the desired angles.

Finishing Process

Coating: Apply a protective finish to the tie rods to enhance corrosion resistance. Common coatings include:
Galvanization: Electro-galvanizing to provide a robust protective layer,color can be golden or sliver.

Quality Control

Inspect the finish for uniformity and adherence to specifications.

Assembly (if applicable)

If the formwork tie rod system requires additional components like nuts, washers, or couplers, assemble these parts together with the tie rods.

Testing

Conduct tensile strength tests on sample tie rods to ensure they can handle the expected loads. This step is crucial for verifying the structural integrity of the finished product.

Packaging and Shipping

Once the tie rods are produced and tested, package them appropriately for transport to job sites or storage, ensuring protection against damage during transit.

Documentation

Maintain documents detailing the production process, quality checks, and test results, which can be important for quality assurance and compliance with construction standards.
