7-9 L-type umbrella anchor bolts are several specially designed pre-embedded parts, including 7-type 9-type L-type umbrella, which are widely used in construction projects for firmly connecting equipment or structural parts to concrete foundations.

Material: including carbon steel, alloy steel, stainless steel (such as 304, 316, 316L, etc.) and other materials, the specific selection depends on the working environment and application requirements.

Grade: The product grade is different mechanical properties grade (such as 4.8 grade, 8.8 grade, 10.9 grade,A2-70, etc.), these grades reflect the tensile strength, yield strength and other mechanical properties of the bolt. Different grades are suitable for different load bearing requirements and working environments.

Advantage:

HIGH Bearing Capacity: The design provides a large contact area, which helps to spread the load, thus providing a higher bearing capacity. Good Stability: Vertical curved hooks can penetrate deep into the concrete, providing additional stability and reducing the possibility of structural movement. Easy to install: can be pre-built before the concrete is poured, simplifying the installation process. Customizable: Anchor bolts can be customized in different lengths and diameters according to project requirements. Corrosion resistance: surface treatments such as hot-dip galvanizing or Dacromet are usually applied to improve the corrosion resistance of the bolts.

Scope of 

application

Building construction: steel columns and concrete foundations used to connect buildings. Bridge construction: for fixing support structures for bridges. Industrial equipment installation: for fixing generators, pumps and other heavy machinery. Infrastructure: for fixing traffic signals, street lights and road signs.
