Steel strand test machineis a test machine for testing the mechanical properties of prestressed steel strand, which can be used to determine the tensile strength of steel strand, the provisions of non proportional extension strength, elastic modulus, elongation and other mechanical properties. Main points for the computer screen display a strand test machine, microcomputer control electric hydraulic servo steel wire testing machine, vertical (horizontal) steel strand relaxation testing machine etc., the common type SDL-300/500 steel strand relaxation testing machine, WEW-600L/1000L computer screen display steel strand test machine, microcomputer WAW-600L/1000L control electro-hydraulic servo steel strand test machine. Is an industrial and mining enterprises, scientific research institutes, colleges and universities, engineering quality supervision station and other departments of the ideal test equipment.
