- Standards: Primarily custom-made; can be manufactured according to drawings or GB/T 799
- Common Strength Grades: Grade 4.8 / Grade 5.8 / Grade 8.8
- Common Materials:
Shank: Q235B, Q355B (Q345B), 45# steel
Base Plate: Q235B steel plate
- Surface Treatment: Natural finish, blackening, electrogalvanized, hot-dip galvanized (preferred for outdoor corrosion protection)
- Structure: One end of the shank is threaded, while the other end is welded to a square or rectangular steel plate; embedded in concrete to form a strong anchorage
Key Product Advantages
- The welded anchor plate structure provides exceptional anchoring strength. The solid steel plate at the base of the product interlocks extensively with the concrete, offering far superior resistance to pull-out, overturning, and vibration compared to hook-type anchor bolts. It is a standard component for heavy-duty equipment and high-rise steel structures.
- The fully welded construction is robust and reliable. The threaded rod is reinforced by welding to the steel plate, ensuring even load distribution and resistance to pull-out or breakage, thereby providing safe and stable long-term load-bearing performance.
- Precise positioning and easy installation: During pre-installation, the steel plate can be directly secured to the formwork, ensuring high positional accuracy. For subsequent equipment installation, simply attach the nut and washer.
- Corrosion-resistant and durable, suitable for harsh environments. Hot-dip galvanization provides rust and corrosion protection, making it ideal for outdoor, coastal, humid, and chemical environments, ensuring a longer service life.
- Dimensions are fully customizable. The bolt diameter, length, steel plate dimensions, and thickness can all be customized according to drawings to accommodate various foundation types.
Typical Applications
- Heavy-duty steel structures, high-rise steel columns, and foundations for overhead cranes and hoists
- Large machine tools, fans, pumps, compressors, and motor bases
- Power transmission towers, wind turbine towers, tower cranes, and construction elevator foundations
- Bridge bearings, port machinery, solar panel mounts, and billboards
- Projects with extremely high requirements for anchoring precision, pull-out resistance, and stability
