Expansion Shells Assembly Right Hand Thread ,Plug Zinc Elect+Gold Passivate

This expansion anchors provide strong, consistent tension and anchorage for a wide range of strata conditions. Expansion anchors can be used with smooth bar for a high performance conventional bolting system. This expansion anchors can be combined with deformed bar and specific resion to make an instal bolt system, a high performance primary bolting system.

Able to achieve tension to 50kN in competent ground

Parallel contact of the expansion shell leafs in bore hole allows for excellent load transfer. Load testing should always be performed to determine the suitability of the anchor.

Over drilling of the hole depth by a minimum 50mm ensures the expansion shell is correctly engaged with the bore hole

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。
