PC strand production GCR Eurodraw designs and installs complete PC strand production plants. PC strand is used as a reinforcement material in pre-stressed concrete beams and other applications for the construction of concrete structures such as bridges and buildings.

A PC strand plant includes: The wire rod batch pickling • and coating plant The wire drawing equipment • The stranding and stress- • relieving line Pickling and coating is the first step in the production of pre-stressed concrete strand. This step is necessary to clean and coat the wire rod surface, so that it can then be drawn down efficiently and economically.

The plant is composed of wire rod storage stalls, followed by tanks containing the chemicals and rinse water to clean and coat the rod. An automatic bridge crane picks up the coils and dips them in sequence in a rinsing tank, a sulphuric acid tank, a zinc phosphate tank and finally into a lime coating tank. This environmentally friendly plant is equipped with all the fume abatement devices, acid regeneration and effluent water treatment equipment to assure that there are no hazardous emissions.

Coating for construction Italian company, IFP manufactures patented steel wire and wire rod (galvanised and Zn/Al alloy coated). Top quality, and with a diameter range of 1.4mm to 16mm, cables and ropes are supplied to end users for offshore cable, bridge ropes and in high tensile structures.

The main plant includes two continuous lines from Belgium’s FIB, with a patented heat treatment and lead cooler system; also pickling, phosphate and galvanising systems to suit the highest international technical standards. The galvanising line can process rod diameters up to 16mm and wires up to 10mm with a wiping system using nitrogen calibration. Final wire tensile strength can be higher than 2160Mpa. Since 2007, IFP has used a Zn/Al (95% Zn / 5% Al alloy) coating for high wire corrosion protection on wires from 2mm to 8mm diameter.
