PC BARS
Screw thread steel bars for the prestressing of concrete are used for permanent works:
Such as it is widely used in large water conservancy projects, industrial and civil
construction of continuous beam and large frame structure, road, rail and anchor engineering of large and medium span Bridges, nuclear power plants. It is well established for its connection,
anchor, strong adhesion, tensioned anchorage safe and reliable, construction is convenient wait
for an advantage, but save steel, reduce component size and weight.
Such as temporary steel pedestal anchoring, and support the dam templates, etc.
These reinforced with sufficient strength to withstand the structure features of heavy load, and the applying prestress and balance structure in the later of the external load.
We have a professional design team, provide technical support to our customers.
