Details about unbonded steel strand and PE coated PC strand
1. Unbonded Prestressing Steel Strand(Unbonded P. C. Strand) has a good corrosion-resistance and less friction of un-bonded tendons and can be easily bended into curve shape.
2. It is suitable for making cast-in-place concrete of long-span and wide building cover, heavy load prefabricated beam and other special structures.
3. It has a lot of characters such as no need of grout hole and grouting, convenient to use, material-saved, bending easily and so on.
Other:
All the production process are made under the ISO 9001-2000 strictly;
Special design according to requirement;
We can provide FE and different diameters and mechanics pc strands according to customer's requirements.
