bonded post tensioning system

what is post-tensioning

post tensioning is a technique for reinforcing concrete. post-tensioning tendons, which are prestressing steel cables inside plastic ducts or sleeves, are positioned in the forms before the concrete is placed. afterwards, once the concrete has gained strength but before the service loads are applied, the cables are pulled tight, or tensioned, and anchored against the outer edges of the concrete.

post-tensioning is a form of prestressing. prestressing simply means that the steel is stressed (pulled or tensioned) before the concrete has to support the service loads. most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed.

FuHua Systems’ Unbonded Monostrand System utilizes the latest extrusion technology to produce unbonded tendons with a uniform coating of abrasion resistant, high density polyethylene sheathing over a low friction, corrosion inhibiting lubricant. All unbonded post tension tendons are fabricated according to the governing ASTM and PTI Standards in our PTI Certified Plant.

Fabricated tendons are tagged, bundled and delivered by construction sequence for ease of field placement.

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。
