FLAT SMOOTH BAR ALLOY TENSION BAR SCREW THREAD BAR
In addition, post-tensioning rod systems provide engineers with greater flexibility in bridge design and construction. Traditional construction methods often require joints to be placed regularly to accommodate expansion and contraction caused by temperature changes. However, the use of a rear tension rod system reduces the occurrence of cracks and minimizes the need for joints, resulting in a smoother and safer ride for commuters. This uninterrupted surface also reduces maintenance effort and costs.
In addition, post-tension rod systems enable a more efficient and faster construction process, minimizing traffic disruptions and shortening project durations. With the ability to prestress bridge sections off-site, builders can significantly reduce on-site construction time and logistical challenges. This advantage is particularly important in densely populated areas where traffic congestion is a major problem.
