General Description
Cold roll steel wire machines are used to produce cold roll steel wire in coils and bars.
Cold roll steel wire machines manufactured by Promostar are complete lines or just single unit able to cold roll the wire rod reducing the diameter to the desired size improving the mechanical properties according to the requirements requested by the market in terms of tensile strength, yield strength and final elongation normally called Agt. In the final step of the process of rolling, if requested, they add the positive ribbing or negative indentation to the wire for concrete reinforcing.
The final product applications are normally reinforcing mesh, stirrups, cages and lattice girders for the civil and industrial construction, foundations and precast industry.
Due to the continuous improvement made by our internal research and development department, we are able to supply machines that, depending on the quality of the entry wire rod material, can produce exit wire material compliant to the worldwide norms for the concrete application like for example (but not only): ASTM A82, ASTM A706, ASTM A1064, DIN 488, SFS1300, IRAM/IAS U500, NCH1173, NBR7480, NCT2289, AS/NZS4671, NTP339 for the production of material according to the grade B500A, B500B, grade 60, grade 80, CA-50 and CA-60.
details
Thanks to more than 40 years of experience in the field of process of rolling, we manufacture high performances automatic turn key plants, that are tailor made on the needs of our customers in terms of layout, products sizes, mechanical properties, level of automation and which allow to finally reduce the transformation costs for each tons of steel wire produced.
Our offer is not limited to the construction of machines and equipment. If required, we are also able to supply valid training, technical assistance and consulting to improve the production of the cold roll process; These services are the keys to reach the target and maintain it over time in terms of efficiency and performance of the plant as well as in terms of correct mechanical properties of the wire produced.
