Product Description

YUANXIAN HIGH-TECH MATERIAL 

Best Quality 7-Wires PC Strand 9.3mm Prestressing Strand for Subway Construction

1x7 Prestressed Steel Strand

Introduce 1x7 prestressed steel strand, low relaxation pre-stressed steel strand is composed by 7 wires, it has the features of high tensile strength and very low relaxation, which make it could replace traditional deformed steel bar well, and save a lot of steel material. Meanwhile ,it make long span concrete construction be possible.

ADVANTAGES

-Primary advantages 

High Tensile Strength

Surface is Clean, and with phosphating layer

Strands distributed neatly on the reel.

 

-Why should I buy this 1x7 prestressed steel strand ?

In the whole process of manufacturing, the test is no less than 10 times, and all details can be traced.

 

-What makes this product different to other factory's 1x7 prestressed steel strand ?

Prestressed steel strand's surface is clean, no grease, no anti-rust oil, this makes the steel have very good bonding performance with concrete.

PC Strand With phosphating layer, it makes the steel be not rust for long time under normal stock condition.

Strands distributed neatly on the reel, this make the strands released very easily, which can reduce the construction time a lot, save cost. 

 

USE

-Where can our 1x7 prestressed steel strand be used?

Our pc strand products are mainly used in construction of long span bridge, hydropower dam, nuclear power plant. And it also could be used long span building, such as large airport, wide cast-in-place floor.

Other use: pole and pile manufacture; hollow core slab manufacture; rock stabilization, slope support, slope reinforcement and other geotechnical engineering; silo construction;

 

-Some common attentions in using of our 1x7 prestressed steel strand.  

Before using, the steel must be tested, only and just only the quality is conform with the requirement from project design party, then the steel can be used.

A high attention must be paid when the PC strand is trucked on very bad road condition or mountain path, a proper fixing and reinforcement to strand coil must be done so that skewed packing coil will not be caused.

 

-How to use?

Fix the coil in the frame, remove all steel strips, find the end of steel strand which is inside of the coil and in the coil eye, pull out this end of pc strand.
