Dome Headed Ball Rock Anchor Bolts M24 Hot Forged Corrosion Resistance

Dome Ball Rock Bolts-Bolt fittings

Hot forged dome ball washer to suit M24 rock bolts

Key Features

• The use of a Dome Ball, with compatible Domed Plate, generally ensures better alignment of the bolt to the roof and together will maximise load transfer from the bolt to the surrounding rock.
• Without the use of the Dome Ball, bending of the bolt at the collar can occur causing local abnormal loading of the bolt and potential early failure.
• Similarly, without the use of a Dome Ball thread, binding can be a problem during installation, limiting the tensioning of the bolt.
• The Dome Ball is suitable for angles of tilt up to 18° with a compatible plate.
• Corrosion protection may be provided by hot dip galvanizing.

Cangzhou Fuhua Prestressing Technology Co., Ltd. was established in 2002. It mainly produces post tension flat anchorage system for housing construction. The company has a research and development center for anchorage, which integrates design, production and sales services. Our products are exported to more than ten countries and regions such as USA, UK, Australia, Dubai, etc. Our products are mainly used in large prestressing projects such as housing construction, high speed railway, bridges and tunnels. At present, we are the first manufacturer in China that can independently produce anchor plates, anchor block and wedges.

Now our factory has various metal forming processes such as casting, forging, cold heading, machining and heat treatment.

The company has a full range of prestressing inspection equipment, from spectrometers and tensile machines for metal forming to metallographic microscopes and hardness testers for the inspection of prestressing clips, as well as static load testing machines. We are able to meet the quality inspection of complete prestressing systems。
