Particularities of production of goods The surface of wire should be clean and smooth, without cracks, delaminations, captured, sunsets, shells, dents, scale, rust, oil and other contaminants. On the surface of the wire allowed the risks (including covered), scratches, local Rabina and individual dents. The depth of these defects shall not exceed tolerances for the wire diameter. Wire comes in etched and bleached condition.
