The core value of pull-out anchors lies in transferring structural loads to deep, stable strata. However, many purchasers only focus on the pull-out force value, neglecting:
Deformation compatibility: Excessive deformation differences between the anchor and the surrounding soil can lead to stress concentration.
Corrosion tolerance: The erosion rate of metal anchors by underground chemical environments can vary by more than 10 times.
Construction error tolerance: Drilling deviations have drastically different effects on the bearing capacity of different types of pull-out anchors.
For example, in water-rich strata, using mortar pull-out anchors with anti-corrosion coatings can extend the lifespan by 3-5 years compared to ordinary steel strand anchors. These hidden costs are often only recognized after an accident occurs.

Hello, I am glad to see your purchase requirements for anchor bolts. We have anchor bolt products. There are no standardized values for the yield strength and tensile strength of anchor bolts; they depend primarily on the specific product standard, material grade, and specifications.
Please be assured. Considering your request for a factory test report (MTR) and traceability for each batch number, a proper MTR document will always include a unique heat number, which is crucial for material traceability. We can provide documents that meet these requirements.
You can tell us the specific standards and grades of the anchor bolts you need to purchase, as well as any other purchasing requirements, so we can provide you with a specific response based on your needs.

Q195 is a low-carbon structural steel. Finding a suitable alternative depends on the specific application.
Some common alternative materials are listed below for reference only:
Q215 has slightly higher strength than Q195, and its applications are largely the same.
DC01 corresponds to the national standard Q195/Q215, with a tensile strength of 270-410 MPa and a yield strength of 130-260 MPa.

When selecting an alternative material, the most crucial factor is to clearly define the specific application, processing method, and minimum requirements for mechanical properties.
The carbon and manganese content of alternative materials may differ from that of Q195, which will affect their welding, forming, and other process properties, requiring corresponding adjustments to the manufacturing process.
