II. Introduction to PC steel Wire induction heating treatment production Line
The whole line of equipments to produce the PC wire with the
capacity of 15,000tons annually.
The product is smooth, screw-tread or three sides indented surface
of PC wire and the diameter range is from φ5.0 to 9.0mm.
The quality standard of the production will meet GB/T5223 China and
relative international standards.
The supplier is responsible for the production process, the quality
of product, the function of machines and production capacity in
guarantee period.
