Unbonded Prestressed Concrete Strand
Silver Dragon hasrevolutionized the way the unbondedprestressed concrete strandis packed. The large tray-type packaging method is replaced by the smallcoil-type packing. This new type of packing facilitates containertransportation. Our company is the earliest to export unbonded prestressed concrete strand to overseas customers.Up till now, it has exported products to a dozen or so countries.

Our company not only emphasizes the product qualitybut also the packaging method and transport. The new-type roll packaging methodis adopted in the packing of the unbounded prestressedconcrete strand. It not only meets the requirement of container transportationbut also reduces the damage caused during the transportation. The unbounded PCstrand can be used to make concrete slabs. It can reduce the slab thickness andgreatly improve the construction speed and structural performance of the slab. It is especially suitablefor making unbondedpost-tensioned concrete, featuring light weight, good quality, and savingmaterial. Recent years have seen its increasing application in civilengineering projects with large permanent loads, large span workshops, andhigh-rise buildings. The product is coated with anticorrosive grease and packedin polythene covers. Its diameter comes in 12.5mm, 12.7mm,15.2mm, 15.24mm, and 15.7mm. It can be suppliedwith tensile strength of 1770MPa or 1860MPa.
