We supply plain or ribbed PC Strand (pre-stressed concrete strand) material ranging from 2 wires, 3 wires, 7 wires and other sizes with high tensile strength and ductility. It's mainly used in civil construction, energy source sea transportation, and so on.

One PC Strand is made of three kinds of wires. The biggest one is in center, 9 smallest near it, 9 outside.
PC strand made of different wires increases its tensile strength greatly. It can be used for bridge or road structure.Pre-concrete strands are bound with straps in one big coil.
With high ductility PC (pre-concrete) strands are packed by straps in coils. PC strands are used in crane beams, floor slabs and stadiums.

Advantage
High tensile strength & low relaxation: Several wires combine together which makes the whole strand high tensile strength.
High bonding force & saving materials: Compared with single reinforced steel bar, PC strand reduces material 40% in mass with high bonding force.
Stability: It maintains toughness for a long time except in strong acid and alkali environment.
High corrosion & crack resistance: Because it's made with steel bars with coatings.
Better performance at high temperature: During processing, it's treated at high temperature after a significant load.
There are many big rolls of PC strands, outside packed with blue film and strips.
PC strands are packed in big coils with film and strips.PC strands are used in railway. Many people are working on it.
With high tensile strength and low relaxation, PC strands are used in railway.
Application
Thanks to the advantage of high tensile strength and corrosion resistance, PC strands are suitable for use in many areas, such as:
Civil construction: bridge structures industrial and factory buildings, road structures, poles, dams, crane beams, floor slabs, foundations, stadiums.
Air space: atomic reactor buildings, rock anchoring components.
Large concrete vessels: gas tanks, such as ethyl tank, LNG tank, LPG tank.
A big bridge is hang by many pieces of PC strands.
With the character of corrosion resistance and high tensile strength, PC strands make the suspension bridge beautiful and stable.Two people are building a flyover bridge with PC strands.
The PC strands can make the flyover bridge stable for a long time.
