F1554 Grade36 Threaded Rod Manufacturers in China

Ningbo Teng Qi Fasteners Co., Ltd is a leading F1554 grade36 threaded rods manufacturer in China. F1554 Grade 36 threaded rod is a specification established by ASTM International (formerly known as the American Society for Testing and Materials). This specification covers straight and bent, headed and headless, carbon, carbon boron, alloy, or high-strength low-alloy steel anchor bolts and threaded rods for use in concrete structures.

F1554 Grade 36 specifically refers to the steel material with a minimum yield strength of 36,000 psi (pounds per square inch). These threaded rods are commonly used in construction applications where a lower-strength fastener is suitable, such as in light to moderately loaded structural steel connections, as well as in various concrete anchoring applications.

The designation “F1554” represents the ASTM standard number, and “Grade 36” indicates the specific grade of steel, specifying its mechanical properties. The threaded rod designation implies that the steel is formed into a rod shape with threads cut into its surface, allowing it to be used with nuts and other threaded components for fastening purposes.

Quality Control of F1554 Grade36 threaded rods:

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.
