difference between plastic corrugated ducts and metal corrugated ductes

What Is the Difference Between Plastic Corrugated Ducts and Metal Corrugated Ductes?

In engineering, the main function of prestressed corrugated ducts is to protect the steel strands from contamination when pouring concrete and ensure the quality of the tensioning. Prestressed corrugated ducts are divided into two types, metal one and plastic one. When using metal corrugated ducts, corrosion resistance is the most troublesome problem for users. However, plastic […]

Introduction of Prestressed Anchorages for Bridges

YJM15 series, YJM13 series stressing anchorages are also called circular anchorages. YJM13 series anchorages can anchor Φ12.7 steel strands, and YJM15 series can anchor Φ15.24 steel strands. This anchorage has good anchoring performance and self-anchoring performance. Tensioning these anchorages generally use YDC series multi-strand jacks. The stressing-end anchorage is composed of four parts: anchor head,
